Using DC operating point calculated from spectre in APS Simualtion over Corners

Johanny Saenz

Hi all.

I have found that Spectre has a better convergence on DC analysis for my specific case. So I'm planning to use DC information from Spectre and then pass it to APS simulator which has better transient performance. 

It could be done easily using writefinal DC value and then read it on APS transient analysis as a node set file. In order to force the sequence of analysis, I have created a dummy variable for a calVal() pass.

However, this approach doesn't work fine when I 'm running corners, because my file is overwritten by each corner run.

How could I read the specific DC operating point for each corner case?

Thanks
