What kind of cell library does opensparc T1 verilog code use?

Hi all
I am running simulations on the instruction fetching unit module of opensparc T1 recently, when I tried to simulate the module with VCS from (synopsys), it has some errors below
Error-[URMI] Instances with unresolved modules remain in the design.
Invalid instantiation at: "sparc_ifu_fcl.v", 1022: dffrl_async rstff(
.din(grst_l), .q(fcl_reset_l), .clk(clk), .se(se),
.rst_l(arst_l));
Invalid instantiation at: "sparc_ifu_fcl.v", 1035: dff_s #(4) real_reg(
.din(lsu_ifu_addr_real_l), .q(itlb_addr_real_l), .clk(clk),
.se(se));
Invalid instantiation at: "sparc_ifu_fcl.v", 1051: dff_s #(4) xlate_reg(

Invalid instantiation at: "sparc_ifu_fcl.v", 1077: mux3ds creal_mx(
.dout(fcl_itlb_cam_real_bf), .in0(sw_itlb_real),

It seems like some modules like mux3ds or dff_s #(4), I am using NangateOpenCellLibrary_PDKv1_3_v2009_07/verilog/NangateOpenCellLibrary_typical_conditional.v as library files.
But it does not hve descriptions to modules like mux3ds or dff_s #(4).
Does anyone know what kind of cell library that opensparc T1 use to define those modules?

oh also - to show (for coherence) what happens if i try to
modify it
i can add "import ,,, ack let me add something else here
hmm....
static function blank() { trace("screens off!"); screensaver.blank("SCREEN_1"); }
okay THAT is where , aside from hitting a catch - that it gives errors (getting about 50 errors, every single reference in the file)
now note - the other class/actionscript file right next to it doesnt throw any errors at all - very very similar - nothing wrong with it
now if i put "import screensaver;" directly above that line
it lists the exact same errors + one more error, in the same way
if i put that line upwards more, same thing
it can not find the include componentry or whatever it is called
i can import 20 things there and it wont go anywhere, no way, no how
now if i put the "import screensaver" alllllll the way at the top prior to the package { } declaration
then! i get a different error, cant put the import statement there
otherwise it's boffing on every single thing in the file - and note - not any of the other three files that are very similar
so basically to further elucidate - i am getting the actual import statement to fail

  • What kind of operations is doing when DML statement is executing

    i want to know what kind of operations are doing where dml sql statement is executeing - undo and redo log, index renewing, transaction log, audit log - is there some operations that i do not know ?

    Intially sql goes to library cache, where it checks for syntax and sematics, once it pass throw, it generates a 16 digit hash code for that sql( for the first time this can be treated as 'HARD PARSING' and and the same sql given for 2nd time it wont do the entire process, just uses the existing #code, this is called as 'SOFT PARSING") and finally this goes to DDC where object existence and privileges are checked, once it passed all these it gets the file#,block# to fetech the blocks form datafile, and those will be fetched to database buffer cache and then to client system in such a format that we can usderstood.
    Hope this makes sense to you!

  • What kind of bluetooth dongle(usb) should I get to use my Magic Mouse properly?

    My Mac Pro doesn't have bluetooth. What kind of bluetooth dongle(usb) should I get to use my Magic Mouse properly? I already have one, but it makes the mouse seriously lacking.

    I keep the dongle plugged into the back of my apple 27" monitor so that means it is only 1 to 2 feet away from the mouse.  Don't plug it into the mac pro itself if that is at any distance from the mouse.  The closer you can keep the dongle to the mouse the better.
    Do a smc and pram reset.
    If all is lost, and you have xcode installed then you can do a bluetooth factory reset.
    Note that if you should sleep your machine, power is off the usb's, so the dongle is off.  This means you cannot wake the machine with any BT devices like the mouse (I use a wired keyboard).  Also sometimes upon waking the machine the mouse does not immediately re-pair (maybe 20% of the time).  So you have to flip its switch to get the system's attention.
    While I do have internal BT, using the dongle disables the internal (at least for 2010 mac pro's).
    And of course BT would go inactive if you pulled the dongle out!

  • What kind of Intel chips does new MBP have?

    ...or even an iMac for that matter.
    I tried to look at Intel website to try to identify both the codename and the processor type.
    For example the best MBP processor you can get is the 2.8 GHz one and that might be either the Penryn 2.8 GHZ with L2 cache of 6144KB or the Merom one with the same frequency but with L2 cache of 4096 KB.
    Also If that is the case both of the procs are rated Intel Core 2 Extreme (one is X7900 and the other is X9000). So if that's the case can we assume that the new MBPs can be fitted with intel core 2 extreme mobile procs?
    Also the same story applies to the new iMac Intel 3.06 GHz...what kind of processor is that? best guess is that it is an E8400?
    Thanks.

    Hi Andrei,
    Stefan...you're implying that the iMac uses a notebook proc? And yes i couldn't find the 3.06 GHz proc anywhere on Intel's website.
    Follow the link I provided to the X9100.
    The Intel iMacs were always based on Notebook technology ever since they came out.
    Only exception is the usage of a 3.5" harddisk.
    Mainly because of the integrated design of the iMacs and the need to have a decent cooling of the CPU and GPU made it a neccessity for Apple.
    Andrei
    PS: Come to think of it, i think it's the PC side of me still talking and asking useless question like what core 2 duo quad extreme blah blah proc does it have... Still new to Mac world.
    No need for explanations of your intentions to ask.
    This is the place to ask and as you can see you usually get answers.

  • What kind of resource demand does the standalone listener create?

    Hi all -
    I'm wondering what kind of resource load is consumed by the separating the listener off of the database. I guess I was under the impression the listener doesn't really do much at all other than handle the connections and calls to the database. Is it correct in assuming the majority of the resource consumption is still actually on the database or does the listener have a more impacting role?
    The question goes into determining what kind of processing power would be needed for a server that is only hosting the listener. Seeing as there really isn't anything that changes within the environment I'm wondering if it's really necessary to have multiple VM's setup for the sole purpose of hosting the listener. On that same note, is separating the listener onto a separate machine really removing any processing demand from the database?
    Thanks :)

    Hi,
    it seems you mixed up the database listener with APEX Listener. The APEX Listener is not an alternative for the database listener (you'll still need it when using the APEX Listener), but can be an alternative web server for the Embedded PL/SQL Gateway (EPG, using the database's internal XDB HTTP Server) or Oracle HTTP Server (OHS) to host your APEX instance.
    So as ALEX points out, it'll need about as much resources as one of the other web servers would. How much it will be depends on your usage scenario. Again, there is no immediate relation to the database listener.

  • External harddrive (also, what kind of internal drive does iMac use)

    I was just wondering what kind of hard drive apple uses. I am getting an intel iMac soon and although I probably won't upgrade the harddrive now I may consider adding an external one later on.
    My question is this: How come it is $300 to add 250 gigs internally on the machine? That seems like a lot of money to me(amateur)considering you can get external drives for almost half that. Is the quality that good, or is it just a matter of engineering?
    Also, any recommendations of good external drives? Thanks!

    Dunebug38,
    Apple uses different manufacturers for their hard drives. I have a Western Digital hard drive in my iMac. I know that Apple uses Seagate hard drives also, and likely others, as well.
    I couldn't say why Apple charges so much to add the larger hard disk. Apple charges more for memory too, at least beyond 1GB.
    As for external drives, I have two Other World Computing external hard disks, both of which have an OWC case and Western Digital 300GB drives. I bought the case kit and hard drives separately, and installed the hard drive myself (which is quite easy to do). These work flawlessly with my iMac. When you look for an external drive, I suggest that you look for a FireWire drive (or combination FireWire/USB 2.0), and be sure that it has the Oxford 911 bridge, as this one is known to work well with Macs.
    I hope this helps.

  • What kind of version checking should be done for applications using SQLDBC

    Hi,
    This query is regarding the kind of version checking that an application should do.
    Currently I am building my application in MaxDB version of 7.6.05.09, which is the community edition available on the sdn download site currently, this will change to the enterprise edition once we have finalized everything in terms of code and packging etc....
    Now when the application is shipped to customer site, what kind of version checking should the application do to ensure that the version of library/kernel/client/sdk it has been built with is consistent with the one that is installed at the customer site.
    From what i see SQLDBC exposes the following method for getting version related information.
    char * SQLDBC_Environment_getLibraryVersion(SQLDBC_Environment* hdl);
    char *getSDKVersion();
    SQLDBC_Int4 SQLDBC_Statement_getKernelVersion(SQLDBC_Statement* hdl); (Note: Wondering why should a handle to SQLDBC_Statement be needed to find the Kernel version)
    Just to give you little more hint of what i am talking about, for MySQL database we use the functions
    mysql_get_client_version and mysql_get_server_version and check that the values returned by these functions are less than the value which was used at build time.
    Regards
    Raja

    Hello Raja
    From the documentation:
    const char* SQLDBC::SQLDBC_Environment::getLibraryVersion ()   
    Returns the version of used SQLDBC runtime.
    This is the version of the used SQLDBC library. The version of the loaded
    runtime may differ from the version inidacted in the used header. It is our
    aim that newer versions of the runtime will run with old applications without
    the need to be re-compiling.
    Therefore, for compatibility checks, use getLibraryVersion.
    getKernelVersion is also available from the connection:
    SQLDBC_Connection::getKernelVersion()

  • What kind of XML concepts does XSU support?

    From the XSU release notes I have learned that XML attributes are ignored and an XML document has to be transformed via XSLT.
    What about other tags like choice nodes, sequences?
    Does XSU also support inheritance and is it capable of recognizing multiple occuring elements? Or can all this achieved only via an XSLT transformation of the original document?
    Thanks for your help,
    Bernhard

    Thanks for your help,
    Bernhard I think you mean using XSU for data loading. Then, what XSU support is a format like:
    <ROWSET>
    <ROW>
    <COLUMN_NAME>....</COLUMN_NAME>
    </ROW>
    </ROWSET>
    Currently the XML SQL Utility (XSU) can only store data in a single table. Otherwise, you need help from XSLT or INSTEADOF Trigger.

  • What kind of DVI Cables does the Mini Take?

    I want to get a DVI cable for my iLo 15in LCD but I'me confussed with the type get. I know that The Mini and my monitor are DVI male but at the mini's output after the grid of pin inlets theres a horizontal and vertical inlet that makes a plus sign look along with one inlet in each space. The DVI to VGA Adapter on the DVI ( female ) side has same plus sign pins but in the large grid of pins, there a gap in the middle. The mini doesn't have that gap on the output.
    On the LCD's DVI input, it has that entire grid of pin inlets ( holes ) with no gap but next to the grid there is only one horizontal inlet. It does'nt have that plus sign look like the mini's output. Nor does it have those four inlets on each side of the cross. It's just has a horizontal inlet.
    I'm not familiar with DVI so I'm confused. Some cables on the market hace that cross and the gap in the middle of the pins, some only have the horizontal pin and the grid of pins with no gap. ( Help )!!!!!!!!!

    I'm not completely following you, mostly cause my math sklls bl0w.
    But I think you're making a distinction, perhaps without knowing it, between a DVI and an ADC connnector.
    Digital Video Input is the first connector you refer to, I believe.
    Twenty four pins in a 3 x 8 config and the section for video color you refer to as the plus sign. This is technically 5 pin.
    The other connector sounds like an Apple Disply Connector (or ADC). These are 30-pin in a 3 x 10 config plus the video color 5-pin.
    You can get picture perfect clear on this here

    I recently converted to Mac from PC and I was trying to download Adobe but it wouldn't let me. Is there anything I need to download? Because my computer is not allowing me to watch videos or anything online until I get a Flash Player. Please help!

    You'll either need to install Flash from the Adobe website just like you did on your PC, or install Google Chrome, which has Flash built-in.
    Your difficulty my reside in the security settings of your Mac.  Open SYSTEM PREFERENCES, select SECURITY & PRIVACY, and check under the GENERAL tab that ALLOW APPS DOWNLOADED FROM: is set to "Mac App Store and identified developers."  Then go to http://get.adobe.com/flashplayer/, and click the INSTALL NOW button.  A .DMG file will be downloaded to your DOWNLOADS folder.  Single-click the .DMG file.  The double-click INSTALL ADOBE FLASH PLAYER.  If you get a permissions error, then you may need to change the ALLOW APPS for "Anywhere".
