VerilogA Problem in MMSIM-7.1

gokce

Hi,

 I am having a problem to simulate my verilogA files under MMSIM 7.1. They work fine under MMSIM-6.0. In spectreout, I get:

ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. Check the log file input.ahdlSimDB/3821_soi12so_Test_Tapeout_Sept09_BinarySearch_veriloga_veriloga.va.BinSearch.ahdlcmi/Linux2.6.11.4-21.9-smp+gcc/ for details. If the compiler ran out of memory, use 'setenv CDS_CMI_COMPLEVEL 0', and try again. If the reason for the failure was a syntax error, contact your Cadence Customer Support representative with the netlist, log files, behavioral model files, and any other information that can help identify the problem.

 In  ahdlcmi.out, I get:

/usr/cds/mmsim-7.1/tools.lnx86/systemc/gcc/4.1/bin/gcc  -march=i486 -ffast-math -O3 -DSYSV -DSVR4 -D_REENTRANT -fPIC   -DconfigSPECTRE -I. -I/usr/cds/mmsim-7.1/tools.lnx86/spectre/ahdlcmi/include -c BinSearch_DcFuncDerLoad.c -o obj/optimize/5.0/BinSearch_DcFuncDerLoad.o || rm -f -f obj/optimize/5.0/BinSearch_DcFuncDerLoad.o;
gcc: error trying to exec 'cc1': execvp: No such file or directory

I attached the log files. Does anyone have an idea?

 

Thanks,

Gokce

    Hi,

     after the installation of MMSIM 7.1, did you configured all packages? During this process veriloga and vhdlams libraries will be compiled and some links will be defined. Maybe this causes problem?

     Kind regards

     I am not sure what you mean by configuring the packages? How do I do this configuration step after installation?

     InstallScape should prompt you automatically at the end of the installation - select all products it offers you, and go through answering the questions.

    Otherwise hit the "configure" link on the main InstallScape page, pick the installation directory, select all the products it gives you the choice of, and answer the questions...

    Regards,

    Andrew.

     I have tried this for MMSIM-7.10.103 Hotfix version. When I select the installation directory /mmsim-7.1 for configuration, I get:

     No Products available for configuration.

     If I check if everything installed correctly, I see OK next to all Spectre products. So I cannot configure anything.

  • Andrew Beckett

    Er, sorry. For some reason I was mixing this up with another question, and was really talking in terms of IUS streams, which definitely do need configuring.

    The one thing that you might have to do with MMSIM71 is to create a link called "tools" in the MMSIM71 installation, pointing to tools.lnx86 . In theory it's not needed, but I always have it there. Normally configuration creates this for most streams, but MMSIM71 does not need configuration, as you've found.

    Regards,

    Andrew.

    Hi Andrew,

     Thanks, for the reply, but I already have that tools->tools.lnx86 link. I believe the problem is that ahdl cannot find the C++/g++ compiler inside the spectre.

     Maybe you aren't setting LD_LIBRARY_PATH to include lib folders from whichever stream(s) you're working with?

  • Andrew Beckett
    In fact you should not do this. It's unnecessary with MMSIM, definitely - it is set by the wrapper scripts for each executable in the tools/bin dir.

    Hi,

    another idea:

    have a look at your environment variable PATH and enshure, that the path to gcc points to the correct directory in the correct MMSIM installation tree. Maybe this causes trouble.

     Good luck

  • Andrew Beckett
    The path to gcc should be set automatically by spectre, to ensure that it picks the version of gcc shipped with the software. So it should be unaffected  by having gcc in the path.

    You might want to check the output of "env" to see if you have any gcc-related variables set though.

    Regards,

    Andrew.
