constructs an instance graph from a Circuit
the Circuit to analyze
Finds the absolute paths (each represented by a Seq of instances representing the chain of hierarchy) of all instances of a particular module.
the name of the selected module
a Seq[Seq[WDefInstance]] of absolute instance paths
A list of absolute paths (each represented by a Seq of instances) of all module instances in the Circuit.
A directed graph showing the instance dependencies among modules in the circuit.
