* | | | xilinx: Fix srl regression.Marcelina Kościelnicka2020-07-121-0/+41
|/ / / | | | | | | | | | | | | | | | | | | Of standard yosys cells, xilinx_srl only works on $_DFF_?_ and $_DFFE_?P_, which get upgraded to $_SDFFE_?P?P_ by dfflegalize at the point where xilinx_srl is called for non-abc9. Fix this by running ff_map.v first, resulting in FDRE cells, which are handled correctly.

| | | | | | | | | | | | | | | | | | - allow inserting only the input pad cell - do not insert the usual buffer if the input pad already acts as a buffer

* | | | clk2fflogic: Consistently treat async control signals as negative hold.Marcelina Kościelnicka2020-07-097-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes some dfflegalize equivalence checks, and breaks others — and I strongly suspect the others are due to bad support for multiple async inputs in `proc` (in particular, lack of proper support for dlatchsr and sketchy circuits on dffsr control inputs).
* | | | dfflegalize: Add special support for const-D latches.Marcelina Kościelnicka2020-07-091-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | Those can be created by `opt_dff` when optimizing `$adff` with const clock, or with D == Q. Make dfflegalize do the opposite transform when such dlatches would be otherwise unimplementable.
