Title: Analysis Order Using Ocean
Post by Berti on Sep 21^st, 2010, 12:25am

Hi all,

I would like to run a transient simulation (tran) followed by a stability analysis (stb). The stability (stb) analysis should use the final operating point of the transient analysis (using the previous operating point option).

This works fine from the Design Environment (GUI). If I start the simulation from an Ocean-Script, the stb analysis always runs first (before the transient analysis).

This is clearly a bug. Does anybody know a work-around?

Cheers

Berti,

How about using actimes and acnames to run the stability analysis?
In your tran command add acnames=[stb] actimes=[final_time].
This functionality is intended to allow you to perform a specified small
signal analysis at a specified time. If you define multiple time points then
the analysis will be performed at each specified time point. BTW, you
won't need the independent stability analysis anymore.

Best Regards,

Sheldon

Indeed, that works.

Thank you Sheldon!
