class TreadleTester 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

Advance time in ticks of the treadle2.chronometry.UTC wallTime, the default is picoseconds, but can be read by the scaleName of the wallTime.
Advance time in ticks of the treadle2.chronometry.UTC wallTime, the default is picoseconds, but can be read by the scaleName of the wallTime. One should probably be advancing by some simple factor of a clock period. The clockInfoList of the options should define this (could be more than one).
- interval
units are in units of the wallTime scale.
