11/21/2023, 3:10 PMCTS_MAX_CAP (which is expressly for clock-tree synthesis which benefits from a different constraint,) there is no way to set max capacitance with the default SDC file, like you can transition and fanout.
Proposal
A new PDK variable, MAX_CAPACITANCE_CONSTRAINT, to join MAX_TRANSITION_CONSTRAINT and MAX_FANOUT_CONSTRAINT.
