hspice parametric
To wpchan05:
thank you for your help!have followed your method,i get the right curve that include the tran and dc curve.But i find little problem in the lis file: “**warning** unknown analysis mode: .. line ignored ”。
I don't know if this problem is important?
The full output lis file does as follows:
* hspice.ini
*
* use ascii only for initial pc hspice release
*
