pub fn emit_sequencer_verilog(name: &str, pf: &ProgramCfgFabric) -> StringExpand description
Emit the autonomous block-walk sequencer for a whole-function CFG fabric: the per-block placed-grid
modules followed by a seq_{name} top that carries the register file + block-PC + terminator FSM +
cycle counter. One block step per clock; done pulses high with the return value on result and the
block-step count on cycles.
