FPGA & HDL — question 7 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
Your testbench achieves what you consider full functional coverage and passes cleanly in simulation. When you load the same bitstream onto the board, the design fails right after power-up but then, if you press the manual reset button, it runs correctly from then on. What would you suspect first, and how would you verify it without just guessing?
