Possible to mask out columns from constraint template?

Question asked by bjorn.nilsson on Jul 5, 2017

Is it possible to mask out or exclude certain columns from a constraint template so that the current value of this column is preserved when the template is applied to a net?


I have set up match-groups matching a lot of differentieal pairs against eachother. Then I realized I had to specify the topology for those nets as well and thought that using constraint templates would be a good idea. However, when assigning the template it also owerwrites my match groups with the value of the constraint template so that all diffpairs are matched in the same group, and that is not what I want.
