Vl-gatearglist-delayredux

Signature

(vl-gatearglist-delayredux delaymod x loc delta) 
  → 
(mv new-x delta)

Arguments

delaymod — A VL_1_BIT_DELAY_N module.
    Guard (vl-module-p delaymod).

x — Gate instance arguments to rewrite.
    Guard (and (vl-plainarglist-p x) (vl-gateargs-ok-for-delayredux-p x)).

loc — Guard (vl-location-p loc).

delta — Guard (vl-delta-p delta).

Returns

new-x — Type (vl-plainarglist-p new-x), given the guard.

delta — Type (vl-delta-p delta), given the guard.
