| * | dfflegalize: Refactor, add aldff support. | Marcelina Kościelnicka | 2021-10-27 | 1 | -1/+16 |

| * | FfData: some refactoring. | Marcelina Kościelnicka | 2021-10-07 | 1 | -448/+24 |
| | | | | | | | | | | | - 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 | ||||
| * | Hook up $aldff support in various passes. | Marcelina Kościelnicka | 2021-10-02 | 1 | -2/+41 |

| * | kernel/ff: Refactor FfData to enable FFs with async load. | Marcelina Kościelnicka | 2021-10-02 | 1 | -114/+211 |
| | | | | | | | | | | | - *_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 | ||||
| * | simplemap: refactor to use FfData. | Marcelina Kościelnicka | 2021-10-02 | 1 | -3/+6 |
