Hi,

Is it possible to use HSPICE optimization for a non-monotonic function?
I am planning to do some optimization by sweeping all values within limits and find the best results.
 

Use random optimizer.
However it could result in local minimum or maximum not global.
Initial guess value is important.

Hi, can provide more infos about this?
I am new to this random optimizer. Thanks

Read HSPICE documents and learn optimization method.

A little similar.

Yes. I did go through HSPICE documents. But seem like it takes bisec method which might not suitable for a nonmonotonic function.
Could you provide me with some examples?
