| * Fix FIRRTL to Verilog process instance subfield assignment.Jim Lawson2019-02-251-8/+20
| | | | | | | | | | | | Don't emit subfield assignments: bits(x, y, z) <= ... - but instead, add them to the reverse-wire-map where they'll be treated at the end of the module. Enable tests which were disabled due to incorrect treatment of subfields. Assume the `$firrtl2verilog` variable contains any additional switches to control verilog generation (i.e. `--no-dedup -X mverilog`)
