// ============================================================================
// The purpose of the following FD* rules are to wrap the flop (which, when
// called with the `_ABC' macro set captures contains only its combinatorial
// called with the `_ABC' macro set captures only its combinatorial
// behaviour) with:
// (a) a special $__ABC_FF_ in front of the FD*'s output, indicating to abc9
// the location of its basic D-Q flop
// (b) a special TECHMAP_REPLACE_.$currQwire that will be used for feedback
// the connectivity of its basic D-Q flop
// (b) a special TECHMAP_REPLACE_.$currQ wire that will be used for feedback
// into the (combinatorial) FD* cell to facilitate clock-enable behaviour
