Helped: Generating boilerplate testbench code and identifying registers.
Got in the way: Missed specific register write sequence requirements.
… There were some issues - for example, you can't write to certain registers in the design until you've set a particular bit in a particular register and it hadn't done that, but I was able to debug this pretty quickly in simulation. I figure that it saved me most of a day's work getting the testbench setup and the design simulating. My expectations were definitely exceeded.
