gives a list of opening heights, as expected. In a case of multiple gate groups defined for a structure, one gets the same result: a single list of openings.
In my case, I have a different rules sets for each gate group in a structure, so they behave in a different way and I would like to obtain simulation results separately for each group.
I was playing with the updn, but that doesn't relate to gate groups, unfortunately.
If anyone hit the same problem and found a solution, please let us know!
