Set PI control codes in tests through normal JTAG debug signals #64

Open sgherbst opened 4 years ago

sgherbst commented 4 years ago

Right now PI-related tests set the PI code through a signal that is not part of the JTAG debug interface. Once issue #62 is resolved they can be set directly through normal JTAG debug signals, which is a better representation of what we would actually be able to do in the lab.

This still doesn't appear to be resolved in the following tests:

  1. cpu_system_tests/pi
  2. cpu_system_tests/pi_pm

The glitch test also has an unusual way of setting the PI control code, but I think that's what we want in that case, since it makes it easier to create different timing scenarios.
