In the execution this is an array write, but the logical definition is just a thin wrapper for update-nth:
Function:
(defun update-vcdwires$ai (stobjs::i stobjs::v vcd-wiremap$a) (declare (xargs :guard (and (vcd-wiremap$ap vcd-wiremap$a) (integerp stobjs::i) (<= 0 stobjs::i) (< stobjs::i (vcdwires$a-length vcd-wiremap$a)) (vcd-wire-p stobjs::v) (stobjs::typep$ stobjs::v t)))) (ec-call (update-nth stobjs::i (vcd-wire-fix$inline stobjs::v) vcd-wiremap$a)))
