fsm_expand - expand FSM cells by merging logic into it¶
yosys> help fsm_expand¶
fsm_expand [-full] [selection]
The fsm_extract pass is conservative about the cells that belong to a finite state machine. This pass can be used to merge additional auxiliary gates into the finite state machine. By default, fsm_expand is still a bit conservative regarding merging larger word-wide cells. Call with -full to consider all cells for merging.
