Hi All,

What constraints might be (should be) used in the DC-Topological, which don't exist in a regular DC?

Are there any special settings?

Thank you!
 

Constraints?? Are you referring to SDC file or any other constraints like swicthes used during optimization?

I think SDC wise they should be same with minor changes in pessimism to ensure that the modelling is more accurate
