I've tried to run Allegro PCB SI 15.5.1 with Hspice 2004.03.
At first, it seems to work very well, but the job is aborted in a few minute.
In the file of waveforms.lis in the "sim" directory,
I can find following error message.
**error** internal timestep too small in transient analysis
time = 6.29875D-09; delta = 1.19326E-20; numnit = 535Originally posted in cdnusers.org by YSShin
Even I give a transition condition as follows,
.tran 0.010000ns 20.000000ns
It is changed.
If you have any experience about this issue or any advice,
Please let me know.
Thanks in advance.
