* xilinx: Improve flip-flop handling.Marcin Koƛcielnicki2019-12-181-1/+2
| | | | | | | | | | | | | | | | 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.
* Moved all tests in arch sub directoryMiodrag Milanovic2019-10-181-0/+31
