16858bbb9d Register signals explicitly
These were previously inferred latches, but now that they are not, we
need to register them explicitly, otherwise they will be 0

6bf7fee64b Increase TCP count to 2
After removing all the inferred latches, we have enough space to have 2
TCP streams instead of just 1. Also we have way more timing slack.

Lesson learned, inferred latches are *really* bad and you should remove
them first before anything else.
