* Replace opt_rmdff with opt_dff.Marcelina Kościelnicka2020-08-071-3/+1
|
* opt_expr: Remove -clkinv option, make it the default.Marcelina Kościelnicka2020-07-311-1/+1
| | | | | Adds -noclkinv option just in case the old behavior was actually useful to someone.
* synth_xilinx: Use opt_dff.Marcelina Kościelnicka2020-07-301-17/+12
| | | | | | | | | 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.
* Remove EXPLICIT_CARRY logic.Keith Rothman2020-07-233-150/+2
| | | | | | | The symbiflow-arch-defs tool chain no longer needs the EXPLICIT_CARRY within yosys itself. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>
* xilinx: Fix srl regression.Marcelina Kościelnicka2020-07-121-2/+2
| | | | | | | Of standard yosys cells, xilinx_srl only works on $_DFF_?_ and $_DFFE_?P_, which get upgraded to $_SDFFE_?P?P_ by dfflegalize at the point where xilinx_srl is called for non-abc9. Fix this by running ff_map.v first, resulting in FDRE cells, which are handled correctly.
* xilinx: Use dfflegalize.Marcelina Kościelnicka2020-07-096-484/+131

| | | | Fixes #2058.

* Use default parameter value in getParamMarcelina Kościelnicka2020-04-211-3/+3
| | | | Fixes #1822.
* Get rid of dffsr2dff.Marcelina Kościelnicka2020-04-151-2/+1
| | | | | | 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.
* Merge pull request #1648 from YosysHQ/eddie/cmp2lcuEddie Hung2020-04-031-2/+1
