VCD 1.3.2 - treadle.vcd.VCD

Accumulates changes to wires in a running circuit. If a wire is changed that it doesn't know about it will add it to the list. Only actual changed values will be seen in final output. This version only supports a single top level scope because right now that is what the firrtl-engine supports. It probably is not too too hard to add, all wires are initialized to 'x' in this version.

version: this software version, but I suppose this could be a DUT version
comment: could be a comment
timeScale: seems to be more text (I like to work in picoseconds)
scope: Not really used here except as the name of the top level module
