about 64 - 32 bit binaries (ultrasim64)

 Hello,

At the tool path "..../MMSIM101/tools/ultrasim/bin" I see the link to executable ultrasim64.

However I have to exclude ultrasim from the 64bit tools in order to run (my machine is i5 and tools run on centOS).

Is there a way to use 64bit binaries for ultrasim ?

 

Another question:

I use the following in order to simulate with spectreVerilog

setenv CDS_AUTO_64BIT EXCLUDE:spectreVerilog

However I remember the tool to argue about not supporting spectreVerilog in 64bit execution.

The simulation did not seem to stop but I ended it as it was too slow. Could not even see the first spectre pass. 

Is the key  spectreVerilog OK to use this tool in 32bit execution? Should I use UltraSim-Verimix or anything else instead?

 

Thanks for your time,

Thodoros

    Thodoros,

    I don't really understand your question. I don't see why you can't use the 64bit binaries for Ultrasim? If you're running on a 64 bit OS (although the OS you're using is not a supported one), you should be able to run 64 bit version. Note that 64 bit doesn't make it faster - it just increases the memory capacity and so the ability to run larger designs.

    You can't use the word spectreVerilog in the CDS_AUTO_64BIT because this has to be the name of an executable, and there is no executable called spectreVerilog. I also believe that running 32 bit only makes sense if you are really using spectreVerilog.

    I would in general advise using AMS Designer (simulator "ams" in ADE) rather than spectreVerilog, because spectreVerilog is ancient and has had no significant work on it in many years (it uses Verilog-XL rather than the "NC" (INCISIVE) digital simulators); AMS Designer is our mainstream mixed-signal simulation solution, and supports spectre, APS, and Ultrasim as the analog solvers, and supports more languages, and also will work in 32 or 64 bit modes.

    Regards,

    Andrew.
