*	simcells: Fix reset polarity for $_DLATCH_???_ cells.	Marcelina Kościelnicka	2020-06-30	1	-4/+4
\|
*	Add new builtin FF types	Marcelina Kościelnicka	2020-06-23	1	-0/+1984
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	The new types include: - FFs with async reset and enable (`$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).
*	Fix the truth table for $_SR_* cells.	Marcelina Kościelnicka	2020-04-15	1	-20/+16
\| \| \| \| \| \| \| \|	This brings the documented behavior for these cells in line with $_DFFSR_* and $_DLATCHSR_*, which is that R has priority over S. The models were already reflecting that behavior. Also get rid of sim-synth mismatch in the models while we're at it.
*	simcells.v: Generate the fine FF cell types by a python script.	Marcin Kościelnicki	2020-04-02	1	-19/+31
\| \| \| \| \| \|	This makes adding more FF types in the future much more manageable. Fixes #1824.
*	Add $_NMUX_, add "abc -g cmos", add proper cmos cell costs	Clifford Wolf	2019-08-06	1	-0/+19
