Wire

Change-wire

Modifying constructor for wire structures.

Syntax

(change-wire x 
             [:name <name>] 
             [:width <width>] 
             [:low-idx <low-idx>] 
             [:delay <delay>] 
             [:revp <revp>] 
             [:type <type>] 
             [:atts <atts>])

This is an often useful alternative to make-wire.

We construct a new wire structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by defprod.

Macro: change-wire

(defmacro change-wire (x &rest args)
  (std::change-aggregate 'wire
                         x args
                         '((:name . wire->name)
                           (:width . wire->width)
                           (:low-idx . wire->low-idx)
                           (:delay . wire->delay)
                           (:revp . wire->revp)
                           (:type . wire->type)
                           (:atts . wire->atts))
                         'change-wire
                         'remake-wire))
