* techmap: Add _TECHMAP_CELLNAME_ special parameter.Marcelina Kościelnicka2020-07-211-0/+1
| | | | | | | This parameter will resolve to the name of the cell being mapped. The first user of this parameter will be synth_intel_alm's Quartus output, which requires a unique (and preferably descriptive) name passed as a cell parameter for the memory cells.
* Add new builtin FF typesMarcelina Kościelnicka2020-06-231-0/+3
| | | | | | | | | | | | | | The new types include: - FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`) - FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`) - FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`) - FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`) - FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`) - latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`) The new FF types are not actually used anywhere yet (this is left for future commits).
