spectre 32 bit or 64 bit?

 By default, all tools get invoked from 32-bit.  To enable 64-bit tools, I place the following in my start up file:

          setenv CDS_AUTO_64BIT  "EXCLUDE:si.exe"

This invokes everything as 64-bit except for si.exe, which is the tool that exports schematics to CDL netlists. 

Regards, Zach

 Thanks Zach. I will give it a try.

What will happen if I don't add  "EXCLUDE:si.exe" ? Will si.exe work or will not work at all or will it work in 32bit mode?

Please let me know. Thanks again.

If using IC614, setting it to "ALL" will be OK because everything is supported in 64 bit mode. Before that, you'll probably find that CDL netlisting will fail, because whilst "si" itself (the standalone netlister) is supported, the contexts for creating auCdl netlists are not supported on 64 bit. 

Regards,

Andrew.

 Thanks Andrew. I believe we are using latest version of IC61x

  virtuoso -V
@(#)$CDS: virtuoso version 6.1.4-64b 12/02/2010 23:19 (sjfdl064) $

  virtuoso -W
sub-version  IC6.1.4-64b.500.10

 It's the version of the IC tools that matters here - so what "virtuoso -W" tells you. The simulator is from the "MMSIM" stream, and virtuoso/si are from the "IC" stream.

Best Regards,

Andrew.

 hello Andrew!

        I am a beginner of Cadence,please tell me how to set spectre to 64 bits detailly,because I do not know where to enter the commands.  best have some pictures,thank you very much!

  best wishes!

In ADE use Setup->Environment and you'll see a form like below. Check the Run with 64 bit binary checkbox, or if that's not there in the version you're using, type "-64" in the usrCmdLineOption field.

Andrew.

 Hey Andrew,

I am facing a similar issue with my ADE, i am not able to run simulation due to these errors.  i am running ubuntu 13.1, Please help me fix the issue. I have tried the above methods to run in 64bit mode but didn't work, i tried changing the bin/sh file from DASH to BASH yet the issue persists.

As I have said a number of times on these forums, Ubuntu is not a supported OS. So the way to "clear this error" is to use a supported OS. We cannot realistically provide support on every single distribution of Linux that people feel like using (I'm always amazed that companies want to use expensive professional IC design software, but don't run it on an OS that we say the software has been tested on).

Anyway, it looks from the messages above as if "cdsPerl" is not running for some reason. If you try running:

/home/abhinand/edatools/mmsim/tools.lnx86/perl/bin/cdsPerl

and then type (say):

print 1+1;

and enter ctrl-D, what happens? Or does it fail when you run cdsPerl? You didn't say which version of MMSIM you are attempting to use either. The fact that you have a cannot execute binary file is a bit suspicious. What kernel version are you using (what does "uname -a" output)?

Realistically it would be much better if you used a supported OS.

Andrew.
