This gives us complete coverage of Virtex 6+ and Spartan 6 flip-flop capabilities (though not latch capabilities). Older FPGAs also support having both a set and a reset input, which will be handled at a later data.

|/ / / / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code for rerouting wires when inserting tristate buffers was overcomplicated and didn't handle all cases correctly (in particular, only cell connections were rewired — internal connections were not).
