Title: Error launching ncvlog
Post by dinac on Sep 21^st, 2008, 10:09am

Hi all,

I was trying to simulate a verilog-AMS, and make a symbol, but i occured error. (using version: ius_v5.7_qsr1)
---------------------------
ncvlog(64): 05.70-s001: (c) Copyright 1995-2006 Cadence Design Systems, Inc.

ncvlog: *E,AMSN64: Verilog-AMS not supported in 64-bit mode.

-----------------------------------
I guess the tool is automatically invoking 64bit, where do i locate this file, is there a Environment variable to be set?

Thanks
dinac

the variable is either INCA_64BITS
or CDS_AUTO_64BITS
it might be easiest to use
printenv | grep "64"

--
there are versions that support 64bits for ams

Thanks...

i found that by default the ncsim calls from the 64bit directory of $AMSHOME/tools/bin/64bit/

And i see no ncsim.exe.. files in /32bit directory, i see them only in /64bit directory

But i found the version " ius_v6.11" I read that this supports 64bit. so now i am using this version in a 64bit machine. To use this i dont even have to set the 64 bit.

But i am using icfb in 32bit . hope that is ok?

I think the programmer of this tool must misunderstand the Cadence environment variable CDS_AUTO_64BIT.
In order to run 32 bit ncvlog, you need to unset this variable, i.e.
unsetenv CDS_AUTO_64BIT

BTW, set it to NONE or any other value does NOT work.
Just unset this variable.
