Vl-primitive-mkwire

Convenient way to generate an internal wire for a primitive.

Signature

(vl-primitive-mkwire name) → (mv expr vardecl)

Arguments

name — Guard (stringp name).

Returns

expr — Type (vl-expr-p expr).

vardecl — Type (vl-vardecl-p vardecl).

This is similar to vl-occform-mkwire, but our primitives are all one-bit things so we leave out the ranges to make them prettier.
