Marcin Kościelnicki	aff6ad1ce0	xilinx: Improve flip-flop handling. ... This adds support for infering more kinds of flip-flops: - FFs with async set/reset and clock enable - FFs with sync set/reset - FFs with sync set/reset and clock enable Some passes have been moved (and some added) in order for dff2dffs to work correctly. 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.	2019-12-18 13:43:43 +01:00
