Marcelina Kościelnicka 347dd01c2f xilinx: Fix srl regression. 
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.

  buffer

Merge pull request #2244 from antmicro/logic 
Add logic type support to parameters
 2020-07-09 18:39:30 +02:00
Marcelina Kościelnicka 03e28f7ab4 clk2fflogic: Consistently treat async control signals as negative hold. 
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).
 2020-07-09 18:12:47 +02:00
Marcelina Kościelnicka e9c2c1b717 dfflegalize: Add special support for const-D latches. 
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.
