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

(Since version firrtl-interpreter 1.5.0) firrtl-interpreter is end-of-life. Use treadle instead.
