about 64 - 32 bit binaries (ultrasim64)

Thodoros

 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

  •  No, because you're setting CDS_AUTO_64BIT to ALL, it will try to run Ultrasim in 64 bit mode.

    So either do:

    unsetenv CDS_AUTO_64BIT

    or

    setenv CDS_AUTO_64BIT EXCLUDE:ultrasim

    No need to worry about the verilog part, because VerilogXL is only available in 32 bit mode anyway.

    Its nothing to do with LD_LIBRARY_PATH - it's just that you're running Ultrasim in 64 bit mode despite it telling you not to.

    Note that you can run 32 bit applications on 64 bit operating systems - just not the other way around.

    And yes - AMS has all the features of Verilog (or SystemVerilog, or VHDL) - so you can assign busses.

    Kind Regards,

    Andrew.
