I'd like propose a new term.
"cost-based constraints"
It particularly applies to high speed differential... especially after
reading all the comments on "Diff Pairs." There are very few hard and
fast if-you-do-this-it-breaks rules any more. Hence the job is to come
up with a cost function for all your design constraints and develop an
optimized solution. I think I just described what seasoned SI engineers
do in our heads. I'd like to see a tool help with this. One problem I'm
having trouble with is that I haven't discovered a layout tool that is
cost based rather than enforcer based. Maybe some of y'all have come
across one that does this.
