FPGA & HDL — question 8 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.
After place-and-route, your timing report shows setup timing comfortably met with 2 ns of margin at your target frequency, but the same report flags a hold violation of 0.15 ns on a path between two adjacent flip-flops, FF_A driving FF_B directly through a single buffer with almost no logic delay. The report shows clock insertion delay to FF_A is 0.3 ns and to FF_B is 0.6 ns. Explain what's actually being violated here and why it has nothing to do with your clock frequency, then describe how you'd confirm and fix it.
