* | / Ensure \A_SIGNED is never used with $shiftxXiretza2020-08-181-0/+4
| |/ |/| | | | | | | It has no effect on the output ($shiftx doesn't perform any sign extension whatsoever), so an attempt to use it should be caught early.
* | Replace opt_rmdff with opt_dff.Marcelina Kościelnicka2020-08-072-9/+17
|/
* Add dffunmap pass.Marcelina Kościelnicka2020-07-312-0/+108
| | | | | To be used with backends that cannot deal with fancy FF types (like blif or smt).
* opt_expr: Remove -clkinv option, make it the default.Marcelina Kościelnicka2020-07-312-14/+14
| | | | | Adds -noclkinv option just in case the old behavior was actually useful to someone.
* synth_ice40: Use opt_dff.Marcelina Kościelnicka2020-07-302-247/+86
| | | | | | | | | 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.
* synth_xilinx: Use opt_dff.Marcelina Kościelnicka2020-07-305-861/+200
| | | | | | | | | The main part is converting xilinx_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the 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.

* opt_expr: Fix handling of $_XNOR_ cells with A = B.Marcelina Kościelnicka2020-07-291-1/+1
| | | | Fixes #2311.
* equiv_induct: Fix up assumption for $equiv cells in -undef mode.Marcelina Kościelnicka2020-07-271-1/+3
| | | | | | | | | | | | | | | | Before this fix, equiv_induct only assumed that one of the following is true: - defined value of A is equal to defined value of B - A is undefined This lets through valuations where A is defined, B is undefined, and the defined (meaningless) value of B happens to match the defined value of A. Instead, tighten this up to OR of the following: - defined value of A is equal to defined value of B, and B is not undefined - A is undefined

* memory_dff: recognize more dff cellsMarcelina Kościelnicka2020-07-231-11/+112
|
* techmap: Add _TECHMAP_CELLNAME_ special parameter.Marcelina Kościelnicka2020-07-211-0/+6
| | | | | | | 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.
* qbfsat: Add `-solver-option` option.Alberto Gonzalez2020-07-202-1/+15
|
* opt_merge: Dedup one more use of FF cell type list.Marcelina Kościelnicka2020-07-151-3/+1
|
* proc_dlatch: Remove init values for combinatorial processes.Marcelina Kościelnicka2020-07-121-0/+33
| | | | Fixes #2258.
* dfflegalize: Gather init values from all wires.Marcelina Kościelnicka2020-07-121-1/+1
| | | | Skipping non-selected wires is unsound in an obvious way.
* dfflibmap: Refactor to use dfflegalize internally.Marcelina Kościelnicka2020-07-091-211/+78
|
* clkbufmap: improve input pad handling.Marcelina Kościelnicka2020-07-091-17/+39
| | | | | | - allow inserting only the input pad cell - do not insert the usual buffer if the input pad already acts as a buffer
* clk2fflogic: Consistently treat async control signals as negative hold.Marcelina Kościelnicka2020-07-091-57/+51
| | | | | | | 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).
* dfflegalize: Add special support for const-D latches.Marcelina Kościelnicka2020-07-091-0/+18
| | | | | | Those can be created by `opt_dff` when optimizing `$adff` with const clock, or with D == Q. Make dfflegalize do the opposite transform when such dlatches would be otherwise unimplementable.
* dfflegalize: typo fixMarcelina Kościelnicka2020-07-071-1/+1
|
* Naming fixes.Marcelina Kościelnicka2020-07-052-2/+2
|
* dfflegalize: Prefer mapping dff to sdff before adffMarcelina Kościelnicka2020-07-051-1/+1
| | | | | | This ensures that, when both sync and async FFs are available and abc9 is involved, the sync FFs will be used, and will thus remain available for sequential synthesis.
* opt_expr: Fix crash on $mul optimization with more zeros removed than Y has.Marcelina Kościelnicka2020-07-051-0/+8
| | | | Fixes #2221.
* abc9: only techmap (* abc9_flop *) modulesEddie Hung2020-07-041-1/+1
|
* abc9: techmap from user design to allow abc9_flop modules to be composedEddie Hung2020-07-041-1/+1
| | | | from other primitives
* Add newlines to help text for dfflegalizeRupert Swarbrick2020-07-031-11/+11
| | | | | | | | | | | | | I think these were probably missed by accident. Spotted because GCC spits out lots of messages like this: passes/techmap/dfflegalize.cc:114:7: warning: zero-length gnu_printf format string [-Wformat-zero-length] 114 | log(""); | ^~ (because we tell GCC that the first argument to log() looks like a printf control string in log.h, and a zero length such string triggers a warning).
