3225bfb984 Add help for "-sat" option inside opt_rmdff. "opt" can pass "-sat" too 2019-06-27 22:06:23 +02:00

35fa7b3057 Fix memory leak when one of multiple DFF cells is removed in opt_rmdff 
When there are multiple DFFs and one of them is removed, its reference lingers
inside bit2driver dict. While invoking handle_dff() function for other DFFs,
this broken reference is used isnside sat_import_cell() function.

891ea6512e Improvements in muxcover 
- Slightly under-estimate cost of decoder muxes
- Prefer larger muxes at tree root at same cost
- Don't double-count input cost for partial muxes
- Add debug log output

8767ec3fbd Add a few more filename rewrites 
This now allows a full pipeline to work, something such as:
yosys -p "synth_ecp5 -json ~/work/fpga/prjtrellis/examples/ecp5_evn/blinky.v"

Otherwise, you will get something along the lines of:
ERROR: Can't open output file `~/work/fpga/prjtrellis/examples/ecp5_evn/blinky.v' for writing: No such file or directory
