 // The purpose of the following FD* rules are to wrap the flop with:
 // (a) a special $__ABC9_FF_ in front of the FD*'s output, indicating to abc9
 //     the connectivity of its basic D-Q flop
-// (b) a special _TECHMAP_REPLACE_.$abc9_clock wire to indicate its clock
-//     signal, used to extract the delay target
+// (b) a special _TECHMAP_REPLACE_.$abc9_clock wire to capture its clock
+//     domain (used when partitioning the module so that `abc9' only
+//     performs sequential synthesis (with reachability analysis) correctly on
+//     one domain at a time) and used to infert the delay target
 // (c) a special _TECHMAP_REPLACE_.$abc9_control wire that captures the control
 //     domain (which, combined with this cell type, encodes to `abc9' which
 //     flops may be merged together)
