`delay_mode_zero (and related) are non-normative definitions in the LRM but are widely supported. Does anyone have opinions on whether input and output skews for clocking blocks should be impacted by delay modes? In particular, should clocking block drives to wires be considered to be more "structural" or "behavioral" in nature? My (very weak) opinion is that for regs, the delays should almost certainly be "behavioral" and thus not be impacted by delay mode specification. For nets, I have no opinion at this point since it isn't clear to me whether non-zero output skews to nets are normally being used to model structural net delays (and therefore probably should be impacted) or whether there are other factors in play. So, particularly from the users, any opinions on what you would expect?
