  1. On non-linear edges and over-clocking A response to AIs taken during the Open IBIS Forum Teleconference by David Banas on April 5, 2013.

  2. Definition/illustration of the “shelf”

  3. The shelf yields a rather interesting impulse response: How can we possibly represent this, using a Ramp-only model?

  4. That was at full output driver saturation. • What about a more realistic case? Would the shelf still occur, if I were driving 12.5 Gbps, for instance?

  5. Yes! Although, it’s not as pronounced.

  6. As is evidenced by the new effective impulse response:

  7. So, we need V/T tables, but…

  8. Parser errors are one thing; what about EDA tools? • Simulator A: PASS • Simulator B: PASS • Simulator C: (Stay tuned.) • Note: “PASS” simply means that the typical, gross errors, regarding over-clocked operation, were not observed.
