I have been using the Constraint manager to change the default behavior of things like Auto via etc.(changing via spacing from tech default for example) and it has been working well but I find that as I don't have permission to edit tech file I have to set this up each time I do a new design.
I'd like to apply my custom rules by default for every bit of layout I do, can anyone help me with any skill pointers or tricks to do this, seems like it should be quite simple but i'm failing :(
I've attempted to use techSetParam to do this but am not having much luck with it, perhaps some syntax incorrect I guess. I am using IC 6.1.4
I use this to check the rule, having already set techID
techGetSpacingRule(techID "minEdgeAdjacentLength" "VIA")
this returns a list of the min values, how do I change these values on startup automatically?
