Hello,
I have had similar issues with large netlists in Hspice. I found that
running the simulations on a Linux box with 16GBytes of 1333Mb DDR3 memory
solved the issue. Since Windows XP can only access 3GB of memory (32 bits),
it is very likely you are requesting more memory. You would have to go to
Linux, etc., versus Windows 7, to be able to access more memory because even
on a 64 bit Windows 7 system, the Hspice application is still run in 32 bit
mode. Although, I believe Synopsys will be fixing this soon...
Best regards,
Steve

Subject: [SI-LIST] Problem about Hspice, .sp file too big to import?
Hello all:
I can't import my netlist into my hspice,when i did it, the Hspice would be
no response state. The Hspice software would run all the time and make the
cpu 100%. Is it because my .sp file too big? it is 15M. when i make my .sp
file smaller,reduce component,Hspice can simulate correctly. So my Circuit
description in .sp file should be ok.
My Hspice version is <Hspice A-2008>. System is WinXP 32, 2G Memory.What is
the problem? if I have to describe a huge circuit netlist, if the .sp
netlist have to be so big,what can i do?
Thanks a lot in advance.
