Got the DUT working (:

[rslawson]

Okay so maybe this commit is a bit more than that. Here's a list of the things that changed:

• Vivado logging directory is now configurable in the CI file. Currently, this is set to _build/hitl/. Moved to Allow setting of the Vivado logging directory #725
• Remove set -x from the OpenOCD start script, which I introduced in the head commit of the original demo DUT branch.
• Fixes to the TCL file for OpenOCD. Why do these fixes make it work? Great question.
• Fixes to the demo DUT. This includes:
  • Adding a whoami Circuit that allows reporting of a 32 bit identifier over Wishbone.
  • Adding a debugging ILA to both the DUT and testing wrapper.
  • Changing the reset on the FINC/FDEC pulse shaper to be on all the probe_all_programmed signal.
  • Adjusting the reduction of the FIFO overflow/underflow signals from and to or.
  • Changing noFifoOverflows and noFifoUnderflows to fifoOverflows and fifoUnderflows respectively, and adjusting their usage in the test wrapper.
• Changes to the demo DUT driver. This includes:
  • Deasserting probe_all_programmed in the case that more test cases are added later. This will prevent any issues from occurring should that happen, otherwise it's harmless.
  • Actually asserting probe_all_programmed once all devices are programmed.
  • Setting longer timeouts for OpenOCD and GDB to terminate.
  • Adding in device ID checks using GDB memory inspection of the new whoami Wishbone components.
  • Actually starting the clock control program on all devices.
• Added a setTimeout function to our GDB utility file. Moved to Add wrapper function around the set timeout GDB command. #726
• Added a catch to running the driver function in Shake, allowing execution to continue to downloading the ILA data. Moved to Add a catch to the driver function to allow ILA data to be downloaded. #727
