| * | coolrunner2: Separate and improve buffer cell insertion passR. Ou2020-02-164-54/+163
| |/ | | | | | | | | | | | | The new pass will contain all of the logic for inserting "passthrough" product term and XOR cells as appropriate for the architecture. For example, this commit fixes connecting an input pin directly to another output pin with no logic in between.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The if(str == node->str) is in fact necessary (otherwise causes generate for in Multiplier_2D in tests/simple/multiplier.v to fail with error message "Right hand side of 3rd expression of generate for-loop is not constant!"). Note: in PeterCrozier's implementation, the break only breaks out of the switch-case, not the outer for loop.
