whitequark e54c7e951c opt_lut: refactor to use a worker. NFC. 2018-12-05 16:30:37 +00:00
whitequark ea4870b126 synth_ice40: add -relut option, to run ice40_unlut and opt_lut. 2018-12-05 16:30:37 +00:00
whitequark 9e072ec21f opt_lut: new pass, to combine LUTs for tighter packing. 2018-12-05 16:30:37 +00:00
whitequark 1719aa88ac Extract ice40_unlut pass from ice40_opt. 
Currently, `ice40_opt -unlut` would map SB_LUT4 to $lut and convert
them back to logic immediately. This is not desirable if the goal
is to operate on $lut cells. If this is desirable, the same result
as `ice40_opt -unlut` can be achieved by running simplemap and opt
after ice40_unlut.
