class FirrtlTerp extends SimpleLogger

This is the Firrtl interpreter. It is the top level control engine that controls the simulation of a circuit running.

It coordinates updating of the circuit's inputs (other elements, nodes, registers, etc can be forced to values) and querying the circuits outputs (or optionally other circuit components)

This mainly involves updating of a circuit state instance by using a expression evaluator on a dependency graph.

    Creates a concrete based on current circuit and the value and poisoned state It uses the type of any existing value for name and if it can't find that it looks up the type in the dependency graph this handles setting SInts with negative values, from positive bigInts when sized appropriately
