I want to run hspice.But it say no free disk.But I see that I still have 14 GB.
I think may be convergence.
How do I do that I can run smoothly?
Thanks.
 

spice .option probe

Hi ilter.
I can't understand your problem exactly. Did you open the sp file from your hard disk? Or maybe there's a problem with addressing. All your addresses should be in DOS format, i.e. no space in your file address. But I have never had any error like yours.
If you still have the same problem, please send your netlist and/or your output lis file.
Good luck.

Regards,
EZT
 

.unprotect hspice

I run in work station or pc hspice.
The result is the same.
Thanks.
 

.options probe hspice

what's the error message u got ?
I had check ur an.lis file, but it seem that the final error were not listed yet.
1. u can reduce the file size by probe some node first, i.e.
remove/comment the line
* .option post = 2
and a a line
.option probe
2. reduce the *.lis file by
.protect
.lib '.\rf018.l' tt
.unprotect


try it again!
