I spent most of this week debugging the RTL. I compiled the finished portion of the RTL and resolved all the lint issues with my portion of the code. I then traced through the most basic test case I wrote INCR.agc. This test case branched then incremented a few addresses in memory before ending. Getting this test case to work required me to catch several bugs. One with the reset value of the pipeline registers, one with reading from ROM, a couple misconceptions in the addressing unit and in the pipeline and some issues in the decoder. According to the schedule Donny and I have one more week till we pass all the test cases. We are on schedule but need to stay work hard next week to stay on schedule.
