| * | Replace opt_rmdff with opt_dff. | Marcelina Kościelnicka | 2020-08-07 | 1 | -3/+1 |
| | | |||||
| * | synth_ice40: Use opt_dff. | Marcelina Kościelnicka | 2020-07-30 | 1 | -8/+4 |
| | | | | | | | | | | The main part is converting ice40_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the mux patterns on its own. The fsm call has been moved upwards because the passes cannot deal with $dffe/$sdff*, and other optimizations don't help it much anyway. | ||||
| * | ice40: Use dfflegalize. | Marcelina Kościelnicka | 2020-07-05 | 1 | -5/+4 |
| | | |||||
| * | Update dff2dffe, dff2dffs, zinit to new FF types. | Marcelina Kościelnicka | 2020-06-23 | 1 | -1/+1 |

| * | Get rid of dffsr2dff. | Marcelina Kościelnicka | 2020-04-15 | 1 | -1/+0 |
| | | | | | | | This pass is a proper subset of opt_rmdff, which is called by opt, which is called by every synth flow in the coarse part. Thus, it never actually does anything and can be safely removed. | ||||
