hsim error: segmentation violation, aborting…

[rhearao]

Hi guys,

"error: segmentation violation, aborting… " happens when I use hsim to run flash memory fullchip simulation. Has anyone ever met this issue before?
if I set the global precision to 1) hsimspeed=3 hsimspice=0 hsimanalog=0 It will use up all memory and terminate at ~90%
2) or set: hsimspeed=3 hsimspice=1 hsimanalog=1 The output is "error: segmentation violation, aborting… "
3) otherwise set: hsimspeed=4 hsimspice=0 hsimanalog=0 or lower precision The simulation would finish but the function is not accurate enough.

Looking forward to any kindly reply!
Thanks.

Segmentation violation usually also means "short of memory" (data segment runs into code segment). Try to spend more memory -- if only virtual memory -- for your sim. process!

while simulating it only used about 5% memory (total 74G ), I think memory is enough for the simulation.
It's wield that I can run FF corner seperately, but if I use .alter in the .sp file the simulation will`` terminate.
for example
: xxx.lib tt
xxx
.alter
xxx.lib ff
xxx
.alter
xxx.lib ss
xxx

When you want to change the LIB within an .ALTER block, you should first delete the old LIB, AFAIR:
