About OpenSPARCT1.1.4 simulation

Hi,
We have tried running regression of OpenSPARCT1.1.4 with follow command:
sims -sim_type=ncv -group=thread1_mini -novera_build -novera_run
It runs correctly. But when we check the file $pwd/2007_05_29/config.v,
there is no any information like `define FPGA_SYN_NO_SPU
`define FPGA_SYN_1THREAD
`define FPGA_SYN
Can we believe it runs in the thread1_mini envirement instead of core1 envirement?
shall we write like this:
sims -sim_type=ncv -group=thread1_mini -novera_build -novera_run -config_rtl="FPGA_SYN_NO_SPU" -config_rtl="FPGA_SYN_1THREAD" -config_rtl="FPGA_SYN" ?
Who can help us ? Thanks!

-config_rtl="FPGA_SYN_NO_SPU"
-config_rtl="FPGA_SYN_1THREAD"
-config_rtl="FPGA_SYN" ?Yes, this is the way to build single thread model specifically for FPGAs. Notice that these three flags are orthogonal. In other words, FPGA_SYN_1THREAD creates single thread model. FPGA_SYN_NO_SPU removes SPU from the model and FPGA_SYN is primarily to replace custom implementation for some logic with FPGA synthesizable code. If you are targeting FPGA technology, and are concerned about the size of the design, then enabling all three flags gives the lowest possible area.
Also note that the correct syntax of the sims command is -
sims -sim_type=ncv -group=thread1_mini -novera_build -novera_run -vcs_build_args=+define+FPGA_SYN -vcs_build_args=+define+FPGA_SYN_1THREAD -vcs_build_args=+define+FPGA_SYN_NO_SPU

Looking for opensparcT1 slowest rate simulation

Hi,
I've downloaded and ran opensparcT1 chip8_mini regression.
According to the regression report.log file, slowest rate simulation was *~190[Hz]*:
"./iob_int_disp_9:chip8_mini:chip8_mini:0/status.log:Cyc= 107199, Sec= 563.730, C/S= 190.2"
I'm looking for a slower rate testcase, *30[Hz]* and less. It should Probably be a chip testcase where all Interfaces are toggled extensively at the same time.
Is it available in opensparc T1 env?
what is the testcase name?
and finally,
How can I ran single testcase instead of full/mini regression?
Thanks for your help,
Yaniv.

Hi CalebC,
Using the PULSE_VOLTAGE component (Sources»Signal Voltage Sources), you can generate a pulsed source as you describe. The three attributes that sound of interest to you are:
Initial value: This is the "zero level" as mentioned in your question
Pulsed value: This is the "one level"
Delay Time: This is the turn-on delay.
The rest of your queries, such as those regarding photon density, sound contextual to your problem rather than a function that Multisim performs, I can't really help you there!
I hope this helps, good luck!

How to use the functionality of Simulation for the Transaction MIRO

Hi Group,
I have a requirement to call SAP from MS Excel and check for the SImulation option as under:
The Excel will pass the values of Invoice Number, Posting date, PO number, PO Item number, Company code and etc., through the call of BAPI   -   'BAPI_INCOMINGINVOICE_CREATE' in order to create Invoice in the SAP system.
But the above BAPI is creating the Invoices in SAP system. Rather, I need to just check(thru SIMULATION) the records and come back to MS Excel with the MIRO numbers that will be created and the errror messages that will be returned back.
In summary, I have to add two Buttons as:
   POST : this has to create MIRO(invoice Numbers) in the SAP System(populating the Success/Error Messages by calling
               the above BAPI   - This functionality is working fine now
   SIMULATE: this has to do same functionality of "POST" option but should not create MIROs in the SAP system
                      Currently I am not able to achieve this as the above BAPI is creating MIROs in SAP.
Kindly provide your inputs on how to go about incorporating the above SIMULATION functionality, by giving some simulation BAPIs that can be used for my functionality.
Thanks for your help in advance.
Regards,
Vishnu.

Hi Group,
In continuation to my previous posting, I would like to give more inputs as under:
when I was using the BAPI - BAPI_INCOMINGINVOICE_CREATE (unless I commit the transaction), MIRO would not be created in the system.
Now, when I run the BAPI again with a different set of data, the Invoice Number is getting incremented by one.... this I dont need, if the Invoice is not committed and if I run the next time, I need to get the same Invoice Number....
How can I achieve this task?
Kindly let me know your inputs on this.
Regards,
Vishnu.

Input for CD Linear Simulation.vi in a Simulation Loop

Hi I'm new to LabView and I was trying to implement a real time estimator for a linear system, so a steady
state gain is acceptable (estimator doesn't need to be adaptive). It will be
implemented in real time target (cDAQ). The estimator will get the acquired
data (there are 2 inputs and 1 output) from the real system.
I have learned and tried few different ways to do it but finally decided to try using CD State
Estimator.vi (standalone) in a Simulation Loop. My questions are:
1. I found that the only way to use the estimator model with the acquired input is by
using CD Linear Simulation.vi. Is there another alternative to do the
estimation?
2. However, with CD Linear Simulation.vi I had problem: According
to the LabView help, if the input signals are more than 1, we have to specify
the input as 2D array with smaller dimension as the number of channels and the
larger dimension as number of points in each channel.
While for every execution in the loop I will get only 2 x 1 data (see appended array 3 in the
attached example file). How can I be able to use the measured data as the two
inputs for the CD Linear Simulation.vi?
Thank you.

Hi Mike,
Thanks for the reply.
I browsed through some examples and tried some things; here are the updates, maybe useful for others in the future.
About the CD Linear Simulation.vi; In the example finder I found CDEx Kalman Filter.vi which uses CD Linear Simulation.vi to compare the estimation with real system states for two inputs. The number of samples of the inputs was given as a constant (e.g. N samples), from which the array of N x 2 data is built and fed to CD Linear Simulation.vi. So up to now I can’t see a way of using CD Linear Simulation for feeding input to the estimator model built from CD State Estimator.vi in a “real time “ way.
I look forward to hearing from anyone if it can be done.
So, from here I tried another alternative to implement this real time estimator: using Discrete State Space Function. So I generate the estimator state space model in Mathscript and feed it to that function.
I use kalman (mathscript) function to generate the estimator model.
Interesting thing is, (although irrelevant with my original enquiry), that this kalman command seems not generate correct estimator model with multiple input (e.g. if in the original system there are inputs u1 and u2 with one output y, I expect the generated estimator model would have three inputs i.e. u1, u2, and y. But the generated estimator only has one input (??)).
I remember that the kalman command from Matlab has the same problem which I neglected at that time.
So this time in labView I also did the same thing as the last time, which is taking the gain generated from the same kalman command and build manually the A and B matrices of the estimator.
I haven't browsed though to see if someone has used this kalman command for multi input system and noticed this.
Nevertheless, this alternative seems working well so hopefully it works well too with the RT target.
Thanks.

IOS Simulator failed to install the application

I just installed OS X Mavericks then downloaded XCODE. Just to test it, I created a Single View Controller application. I went to the storyboard and added a label just so I could see something come up when I would run the app. I did not add any code. I ran the app which builds fine, but I then get a IOS Simulator failed to install the application. Rememer, this is a clean install of Mavericks, a clean install of XCODE and the first app created. I repeated this for a Master-Detail application and get the same result. I did not change any settings in XCODE from that which is installed by default. Just wanted to go through a build and run to verify things before I start writing a real app.
I checked the forums which talk about telling the IOS Simulator to Reset Content and Settings. This does not resolve it. I get a black simulator screen. There was other talk about removing a file: ~/Library/Application Support/iPhone Simulator
but that file does not exist. The forums also talk about building IOS 6 apps and then having a problem after building for IOS 7. But again, no default parameters were changed and it is building an IOS 7 app for the first time and has only been generating IOS 7 apps.
Any ideas why the simulator won't load any of the simple apps?

Since everything else I tried had failed, I uninstalled XCODE, reset the Mac then re-installed XCODE and the apps all started loading properly into the simulator. After I installed OS X Mavericks the first thing I did was install XCODE and made no configuration changes to it. Yet I had the issue reported. But now with reloading XCODE all seems fine.

Simulation problem

I'm asking about wrong SW after Simulation processing.
First I wrote a .scr file run with SW=0x9000 with jcwde
but after converting to .cap file and generating an APDU script file by using scriptgen iused this file as input to the apdutool while running cref but the in the output file the SW becomes equal SW1: 64, SW2: 44, this is in creating the applet, and all APDUs also return with SW = 0x9000, I hope to give me a solution for that, and I will be thankfull.

I think you forget add header and trailer in *.scr file
you NEED scr file be like this IF U USE "CREF",(no need if use jcwde)
// start of scr file
powerup;
// Select the installer applet
0x00 0xA4 0x04 0x00 0x09 0xa0 0x00 0x00 0x00 0x62 0x03 0x01 0x08 0x01 0x7F;
// 90 00 = SW_NO_ERROR
//text from scriptgen
original text
original text
original text
original text
//end of text from scriptgen
// "create" with correspond AID

How to send concurrent xml request to Soap service.

Hi
I am working in a scenario. where i need to send more than 10 concurrent xml request to soap service hosted in IIS.
and that service directly pools to biztalk recieve location. Presently i am sending a single request through soap ui.
Is there any tool available to send more than 10 xml request to service. If not then how we send through C#.code

Hi Anagh,
Microsoft BizTalk LoadGen 2007 Tool would be the perfect fit for your requirement where you need to send "Concurrent" request to SOAP.
Using LoadGen you can configure it use to number of concurrent threads to send messages. In its config file, it has a section called
<NumThreadsPerSection> which can be used to set the number of concurrent threads that LoadGen will use to send messages.
Read one of my old blogposts where I have talked about using LoadGen for simulating message load for SOAP services.

"Application Error" on Portal Connecting to MS SQL

Hello together,...
i'm very new to the SAP Portal.
I have build an application that uses the BI-JDBC Connector to connect to an MS SQL-Server. I have also build an application with VC that reads a tbale of the Database. These parts are working perfectly.
Now i have tried to build an iView that allows to change an entry in the Database. When i send the SQL Statement i get a pop-up Message:
TITLE: "Applicatione Error"
Message: "null"
Now the strange thing about this is, that the changes were actually made in the database, even though the error occurs.
The Problem must be the SQL Statement i've used. To prevent errors in this, i post the SQL Statement at this point:
"UPDATE Lieferanten SET Firma = '"&@Firma&"', Strasse = '"&@Strasse&"', Ort = '"&@Ort&"', Plz = '"&@Plz&"' WHERE Lieferantennummer = '"&@Lieferantennummer&"'"
Has anyone a small hint for me, how i can fix this Problem?

Is there a driver available to connect to MS SQL Server from a java application or servlet running on UNIX or Linux box? Quite probably. Go here to find out:
http://industry.java.sun.com/products/jdbc/drivers
Is there a way to create ODBC connection to it on UNIX?I've heard something about a Unix ODBC simulator, but I wouldn't bother with that. ODBC is not necessary in this situation.

Apple Hypervisor or OSX in virtual machine?

Hi there,
I think about buying a MBP but I need to run Linux as primary OS- this is not topic of discussion, believe me, I need it like that.
Two possible Solutions:
1) Run OSX as a virtual machine on linux: though technically possible, this is not officially supported by any host software: does anyone know about "inofficial" support?
2) Run OSX on a Hypervisor. IS there a hypervisor that runs on Macs (and supports OSX as guest)? I was unable to find infos on the net on that.
Any hints appreciated. I need to decide what laptop to buy next week, and this is the feature that would make me buy a MBP instead of a Thinkpad- so please answer quickly
Kind regards
Peter

You don't seem to be too much in IT guessing from your use of the term "to boot". Maybe someone else with a lot of expierience in vitualization is around here to provide a better answer.
And what other ways are you talking about? I run simulation software that is Linux only and needs all the performance it can get- so I can't see another solution that is as smooth to handle.

Clipping mask fail

Hi there, I have just received a poster back from the printer and have noticed the edge of the clipping mask of the artwork has printed. The graphics consisted of an image (placed as a CMYK tiff) and plain vector graphics over the top in some parts. I had a white rectangle (brought to the front) running from left to right (to edge of page) over the image, then I grouped the all the elements (white rectange still at front) and created a clipping mask (a rounded corner rectangle) about 1cm within the borders of the page to keep it all tidy. Where the white rectangle running over the image and the border of the poster come together there is a hairline of colour of the image. From the full view of the page I could see the line but when I zoomed in uber close it disappeared (same in the PDF). I have seen things appear a bit skewed in high res PDFs before even when you know they are aligned correctly so I didn't worry about it sure it was just previewing incorrectly. Anyhoo! hope I have explained this Ok... can anyone suggest why it happened or how to create the artwork correctly. Cheers, Sarah

I think I know what you're talking about. A little of the image leaked past the white box.
Shouldn't have caused a problem, but it did. Sorry about that.
I simulated your problem. When I did the following, none of the image showed past the white box, in Illustrator or in Acrobat:
1. Draw a big box surrounding the artwork
2. Select this and the white box, make a compound path
3. Select this and the image, make clipping mask.
4. Now bring your round corner rectangle to the front.
5. Select all, make clipping mask.
Hope this helps
