InterpretiveTester

class InterpretiveTester extends AnyRef

Works a lot like the chisel classic tester compiles a firrtl input string and allows poke, peek, expect and step

pokes invalidate the underlying circuit peek, expect and step, recompute (re-validate) the circuit before executing

Important note: port names in LoFirrtl have replaced dot notation with underscore notation so that io.a.b must be referenced as io_a_b
