Moddb-wireidx->path/decl

Convert a wire index to a path relative to the module it's in, and additionally return the wire declaation.

Signature

(moddb-wireidx->path/decl wireidx modidx moddb) 
  → 
(mv path wire)

Arguments

wireidx — Guard (natp wireidx).

modidx — Guard (natp modidx).

moddb — Guard (moddb-ok moddb).

Returns

path — Type (path-p path).

wire — Type (wire-p wire).
