Marcelina Kościelnicka 4e70c30775 FfData: some refactoring. 
- FfData now keeps track of the module and underlying cell, if any (so
  calling emit on FfData created from a cell will replace the existing cell)
- FfData implementation is split off to its own .cc file for faster
  compilation
- the "flip FF data sense by inserting inverters in front and after"
  functionality that zinit uses is moved onto FfData class and beefed up
  to have dffsr support, to support more use cases

Marcelina Kościelnicka 63b9df8693 kernel/ff: Refactor FfData to enable FFs with async load. 
- *_en is split into *_ce (clock enable) and *_aload (async load aka
  latch gate enable), so both can be present at once
- has_d is removed
- has_gclk is added (to have a clear marker for $ff)
- d_is_const and val_d leftovers are removed
- async2sync, clk2fflogic, opt_dff are updated to operate correctly on
  FFs with async load

Marcelina Kościelnicka 1c903d3e47 sim: Add wide port support. 2021-05-25 02:57:32 +02:00
Marcelina Kościelnicka c4cc888b2c kernel/rtlil: Extract some helpers for checking memory cell types. 
There will soon be more (versioned) memory cells, so handle passes that
only care if a cell is memory-related by a simple helper call instead of
a hardcoded list.

qbfsat: Add `-solver-option` option. 2020-07-20 21:54:56 +00:00
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).
