Cascade 2 PLL_ADV in spartan-6 FPGA and dynamic configure

Can I cascade 2 PLL_ADV in spartan-6(XC6SLX25T) FPGA and dynamic configure them?

Hi, , Of course the two PLL_ADV meet the requirements for VCO frequency. The output of first PLL_ADV connect to a BUFG and then to the CLKIN of the second PLL_ADV.
You mean that if change the first PLL_ADV output with dynamic reconfigure, I must reset the second PLL_ADV and then dynamic reconfigure it ?

Variable Substitution and Dynamic Configuration

Hi All,
In Variable Substitution , the name that should be given the the receiver payload should be part of the Source Payload unlike the Dynamic Configuration wherein the file name can be generated dynamically during mapping.
I have the following questions
1.Dont we need to write the UDF for the Variable substitution?
2.Cant we do the Dynamic configuration without writing UDF?If so then how?
3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
Thanks in advance

Hi Shwetha,
1.Dont we need to write the UDF for the Variable substitution?
No. Here we are accessing the contents of the payload to the target. So no UDF required.
2.Cant we do the Dynamic configuration without writing UDF?If so then how?
Yes and No.
Because we can set only few Dynamic configuration values without UDF.
If both source and target are File, then check ASMA on both sender and receiver. Then u can get the source directory name and source file name for target also without any UDF.Also some other parameters.
3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
The file name comes along with the source in the payload as a attribute in header. U can view this in SXMB_MONI, and Dynamic Configuration.
In Dynamic Configuration the file name is generated dynamically.
No the file name is taken as it is from the source, if u want to change dynamically that u have to do in a UDF.
I hope this will clear all doubts,
If nt pl post

Multi-Mapping and Dynamic Configuration

Hello,
Is it possible to use dynamic configuration in mulltip-mapping? (message split?)
in a proxy-mail scenario I am using a multi-mapping. The message gets splited by a specif field.
(Field of source message-SplitByValue(Value Change)-CollapseCOntext->Target Message(1..N)
WIthin the graphical mapping I have a dynamic configuration for the "Mail Subject"
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keySubj = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/Mail", "THeaderSUBJECT");
conf.put(keySubj, pSubject);
return pSubject ;
I have mapped this field to a field in the target message.
The messages are being splitted as expected and the value of pSubject is also correct.
BUT when receiving emails the subject field has the same value for all splitted messages.
My Question is "conf.put(keySubj, pSubject);" overwitting all splitted outgoing messages?
Thanks for the Help
EMW

As stated in http://help.sap.com/saphelp_nw70/helpdata/EN/43/09b16006526e72e10000000a422035/frameset.htm
Adapter-Specific Attributes and Multi-Mappings
In multi-mappings, there are multiple message headers with adapter-specific attributes. The mapping API can only access one message header. This has the following consequences depending on whether there are multiple source or target messages:
●     1:n Transformation
If there are multiple target messages, the header for the adapter-specific attributes is copied for each message. This means that you can only create one header for all adapter-specific attributes, and not individual headers.
●     n:1 Transformation
This variant is only possible for multi-mappings in integration processes. If there is more than one source message, read-access to the adapter-specific attributes of the various message headers is not possible at runtime.
●     m:n Transformation
All afore-mentioned restrictions apply here. Developers can at most write the same adapter-specific attributes for all target messages to the header, without read-access to the attributes of the source messages. m:n transformations are only supported within integration processes.

Henrique.

White Rabbit module for NI's cRIO based on Spartan-6 FPGA: One clock makes you faster and one clock makes you slow

Many distributed networks including those used for 5G communications, power-grid monitoring, and particle physics research need precise time synchronization among the distributed network nodes. CERN’s White Rabbit Ethernet protocol is designed to provide sub-nanosecond accuracy while synchronizing more than 1000 network nodes connected via either fiber or copper. As reported at a status update meeting a week ago, the University of Zürich has developed a plug-in White Rabbit module for National Instrument’s CompactRIO (cRIO) control and monitoring system based on a low-end Xilinx Spartan-6 FPGA and it has been tested by EN-ICE group in CERN’s Engineering Department. Here’s an annotated photo of the board:
The module connects to the network via its optical SFP port and generates disciplined reference clocks that are used by the rest of the local node for network timing synchronization. With the Spartan-6 FPGA clocking at 160MHz, no output clock jitter was detected in the latest design tests.
Prior Xcell Daily coverage of CERN’s White Rabbit protocol:
White Rabbit: When Every Nanosecond (and Subnanosecond) Counts

I'd like to make a correction to the article. It's the University of Zürich who has developed the plug-in cRIO White Rabbit module. The EN-ICE-MTA section at CERN has tested the performance of the module and organised the meeting.

Erasing Flash Memory of Spartan 3E FPGA

Hello,
I'm programming a Spartan 3E FPGA, and I believe there are a few VIs left in the flash memory from the previous user of the board. I'd like to just clear out the flash memory. 've been playing around and can't seem to find how to clear it through LabView on a spartan.
I've already had a look at this.
http://digital.ni.com/public.nsf/allkb/4789525480C3B78C8625714000746BFD\
It should be pretty simple, anyone know how to go about it?
thanks in advance!

Are you referring to the platform flash (XCF04, this can be used to automatically-configure the FPGA on powerup) or the Strataflash (which cannot easily be configured to do so, but can be used for persistent storage)?
If it's the former, I would suggest using iMPACT to clear the flash part. For the later, there are a few examples that interact with the Strataflash, that's as good a starting point as any.

LV2012 crashes when opening LV2010 project containing OOP and dynamic FPGA references

I have a project that was written under LV2010 and has no problems that I am aware of. This project contains OOP and dynamic FPGA references. I am trying to upgrade this project to LV2012. When opening this project under LV2012 (or any subVI containing OOP) I get an error message, as shown in the attached screenshot. Has anyone else observed this problem? I haven't found any relevant postings on this forum yet.
My project is quite large, with many accessors.
Thank you for any assistance you can offer.

Thank you for your response, but the Discussion Forums link that you provided refers to a problem that occurs when exiting a running executable. My problem is different. I am simply opening up a LV2010 project using LV2012. No running of my program is involved.
Anyway, after several days of work, I narrowed down the cause of the LabVIEW crash. My code contained a Disable structure, and within that Disable structure there was a subVI that had an unwired object terminal (set to dynamic dispatch). Deleting the subVI in the Disable structure eliminated the LabVIEW crashing. Weird behavior.

Spartan-6 FPGA Dev Board plays Doom, a first-person shooter video game from 1993

Yesterday, I mentioned a port of Professor Nicklaus Wirth’s Oberon programming language and operating system to Saanlima's Pipistrello, a Spartan-6 FPGA development board. (See “Oberon System Implemented on a Low-Cost FPGA Board.”) There are many uses for a dev board however and one of the other ports to this board is the first-person shooter called “Doom,” which was originally developed to run on DOS PCs by id Software.
This FPGA-based implementation uses a recompilation of a source port called “Chocolate Doom” that runs on a 100MHz Xilinx MicroBlaze soft processor instantiated in the Pipistrello board’s Spartan-6 LX45 FPGA with additional HDL to handle the mouse, game controllers, video, and sound. Now running recompiled code for an x86 microprocessor on an FPGA-based, soft-core processor might not be the most obvious way to fully employ a Spartan-6 FPGA, but I think it’s a pretty cool demo nevertheless.
Here’s a short, 26-second video showing DOOM running in demo mode on the Spartan-6 LX45 FPGA:
Note: There are no sound effects in this short video because we didn’t hook up any speakers to the Pipistrello board.

Excellent!
Gotta try Pac-Man. It is so much like the arcade version from the 80's it's scary. Also, Magnus has the Pipistrello working so well you can re-flash to/from Oberon to Pac-Man (or whatever) almost instantly. I mean, flash and boot in under 2 seconds. Quite impressive.

Is the Nexys2 board (with spartan 3e FPGA) compatible with the FPGA module

Hi my name is DIego and I was wondering if anybody here knows if the NEXYS 2 board (with spartan 3e FPGA) from DIGILENT is compatible
with the LABVIEW FPGA module.
Thanks
Digilent is also the Manufacturer of the SPARTAN 3e STARTER BOARD

Diego:
The NEXYS 2 is not officially supported, but if you'd like to try it, you can attempt to follow the guide for the Spartan 3E here (substituting your NEXYS 2 for the Spartan 3E).
Again, the NEXYS 2 isn't officially supported, so if it doesn't work like the Spartan 3E starter kit board, then you won't be able to use LabVIEW FPGA with it.
Good luck!

Spartan 3e Fpga

Hi Guys,
I have a Doubt Regarding Spartan3e Xup Board,
Does Ni Supports Spartan 3e Fpga or Xup Board. The Driver which is released by ni only supports for Xup board or Fpga?
Regards,
Krish.

Hi,
For the Spartan-3E board (which is bought from Xilinx) to work with Labview FPGA, you need to install a driver which is provided on National Instruments site https://lumen.ni.com/nicif/us/infolvfpgaxilsprtn/content.xhtml ... The driver was developed by NI to make researchers and educators use the more available Spartan-3E boards without a need to buy NI-RIO boards (On which there is a xilinx virtex-5 FPGA).
Till now, I guess this is the only kit supported by NI to work with Labview FPGA, so your other choice is to buy a NI-RIO boards.
Note : The above driver works with Labview FPGA 8.6. You can search the forum to find the 8.5 driver.

Difference between Static SQL Query and Dynamic SQL Query.

Hi,
Please explain the basic difference between static and dynamic sql queries. Please explain with example.

Static: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/static.htm

AFAccountUpdate ArrangementsBroken1 dfsdff 1234 1234
AFAccountUpdate ArrangementsBroken2 dfsdff 1234 1234
AFAccountUpdate ArrangementsBroken2 dfsdff 12345 12345
AFAccountUpdate ArrangementsBroken1 addf 12345 12345
Create table test_pivot_dynamic
pagename varchar(200),
fieldname Varchar(200),
fieldvalue varchar(500),
N9_Router_Account_Number bigint,
TC_Debt_Item_Reference bigint
--Input
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken','addf',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken1','dfsdff',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken2','fder',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken2','dfdfs',12345,12345)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken1','dfdwe',12345,12345)
insert into test_pivot_dynamic Values('AFAccountUpdate1','Arrangements','addf',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate1','Test1','dfsdff',1234,1234)
--Expected output:
Select 1234,1234,'AFAccountUpdate','ArrangementsBroken','addf','ArrangementsBroken1','dfsdff','ArrangementsBroken2','fder','ArrangementsBroken2','fder'
Select 12345,12345,'AFAccountUpdate','ArrangementsBroken','addf','ArrangementsBroken1','dfdwe','ArrangementsBroken2','dfdfs'
Select 1234,1234,'AFAccountUpdate1','Arrangements','addf','Test1','dfsdff'
so basically we have to pivot and dynamic sql and insert the expected output to a common table which will have all the required fields

Credit Management: Difference Between Static and Dynamic Credit Check

Hi,
Could anyone tell the difference Between Static and Dynamic Credit Check?
According to website: http://www.sap-basis-abap.com/sd/difference-between-static-and-dynamic-credit-check.htm ... this is the answer:
====================
Simple Credit Check : Tr.Code - FD32
It Considers the Doc.Value + Open Items.
Doc.Value : Sales Order Has been saved but not delivered
Open Item : Sales Order has been saved , Delivered, Billed & Transfered to FI, but not received the payment from the customer.
Static Credit Check it checks all these doc value & check with the credit limit
1) Open Doc.Value / Sales Order Value : Which is save but not delievered
2) Open Delivery Doc.Value : Which is delivered but not billed
3) Open Billing Doc.Value : Which is billed but not posted to FI
4) Open Item : Which is transfered to FI but not received from the customer.
Dynamic Credit Check         1) Open Doc
                                            2) Open Delivery
                                            3) Open Billing
                                            4) Open Items
                                            5) Horizon Period = Eg.3Months
Here the System will not consider the above 1, 2, 3 & 4 values for the lost 3 months.
====================
Question 1: Could you further explain the above information, if there is any?
Question 2:: What is the Tcode to customize settings of:
a) Simple Credit Check (isn't this same with b) below?)
b) Static Credit Check
c) Dynamic Credit Check

Hi Tanish,
Diff between Static and Dynamic Filters.
Example One at report Level.
Create a variable for a Infoobject say ,Material .
1)In the Query Designer and if u restrict it to some 10 materials at query level, the report will display for only those 10 materials only.This is Static Filter.UR AHrdcoding it to those materials.You cant change them at Query Run time.i.e not changeable by user.
2)If u give the variable as input ,and when u run the query ,u can can choose the material,may 10 may be 1 or may 20 .It is dynamic.Changeable by user at run time
Example Two at DTP and Start Routine Level,say Document Type.
1)If u give filters in Start routine it is Static as u cannot change it in Production,not changeable by user.
2)f u give filters in DTP it is Dyanamic as u can change it in Production.U can give any doc type,Changeable by user at run time.
Hope it is Understood.

Perform static and dynamic check together on a customer?

Hello All,
Is it possible to perform static and dynamic check together on a customer?
I believe standard SAP does not allow both options together.
The scenario is: My client has customer who orders products 1 year in advance and create sales order with a future delivery date. The customer might have balance due on their account which is close to the credit limit. As a result the sale order should be blocked as if the automatic credit check is "Static". This would allow our customer service to call the customer and arrange for the payments.
Then 11 months later, a dynamic check should be performed on the customer to make sure the past due is under the credit limit. If the past due is over credit limit, the sales order must be blocked for delivery as if the credit check was "Dynamic" with 30 days horizon. This would again give our customer service time to settle the payment with the customer.
If anyone has implemented such a scenario, can you please give me an overview of how you did it?
Thanks very much in advance and Text Removed.
With Regards,
AM

Static and Dynamic Cannot be Performed together. They are mutually exclusive events.
Credit check can be performed either at Sale order level or at Delivery / PGI Level.
FCV3 is a good report to see whether a customer would fail a credit check. ( suitable for your customer service )
Coming to your Point , Assuming that the customer is eligible for a Credit of 50 Lacs. Now the Customer has placed an order for 60 Lacs. We set the Customer credit checking at order level . The Customers Sale order would get blocked.
The Customer service will follow up for the payment and see to it that it is made. Assume the customer has made a payment for 70 Lacs.
Now let us have a look at the account statement of the customer.
Account Statement : Customer Cr : 70 Lacs. Dr : 0. ( because no delivery and invoice so far has been made )
So we are supposed to deliver the Material worth value of 60 Lacs.
The First sale order worth 60 Lacs has been unblocked in VKM3. Now at the time of Delivery level why would you want to chekc the Credit limit again ? It has already passed the credit check.
It is not necessary to check credit limit . Because you have already performed the same at the order level.
Now the customer has come again and raised another sale order for 80 Lacs. The System would block him.
The system will never block the Previous delivery which you are, due for delivery to the customer.
If we keep on checking the Credits without delivering we would end up only raising in Sale orders and no Delivery to the Customer at all. The Debit side of his account will always be 0.
So i donot think Static and dynamic is needed . you can go for either Static or Dynamic.
