Title: need help:ncvlog error
Post by pk9617 on Dec 13^th, 2011, 4:57am

i was trying to simulate a verilog-AMS, 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 went through the /32bit directory... the files of ncvlog,nclaunch ...
did not existed. I dont know why. i run the executable "ncvlog" in directory "install_dir/tools/bin", but it is still 64-bit mode.

is there anything wrong in my installation of ius?
how can i resolve this problem? :(

thanks

pk9617,
IUS 5.7 is very old. Try updating to a recent version.
Also check if option -64bit is somewhere set as default.

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.

Code:

unsetenv CDS_AUTO_64BIT

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