On-the-Fly Hardware Accurate Simulation, New Meridian CDC, ASICON Tutorial

Thursday, October 8th, 2015

In this blog, we are presenting the highlights from Real Intent’s Fall 2015 Verification Newsletter. First are some thoughts from Prakash Narain, CEO, followed by an introduction to the new 2015 release of Meridian CDC for clock-domain and reset-domain crossing sign-off, and finally a review of our fall events including an ASICON tutorial.

Thoughts From Prakash Narain, President and CEO…

Most functional verification for SoC and FPGA designs is done prior to RTL hand-off to digital synthesis, since gate-level simulations take longer to complete and are significantly harder to debug.  However, gate-level simulations are still needed to verify some circuit behavior.  Unfortunately, X’s in gate-level simulations can cause differences in the RTL simulation output and the gate-level simulation output.  X’s generally exist in all designs – it can be difficult to prevent this for practical reasons.  Simulation results may be different because of X’s that are hidden in the RTL simulation by X-optimism, or additional X’s may exist due to X-pessimism in gate-level simulations. Pessimism can be fixed by overriding the simulator because you know that real hardware would always resolve to a deterministic value. The challenge is confirming that the X value is a result of X-pessimism and not simply X-propagation, and then forcing it to the right value at the right point in time so the simulation matches that of real hardware.
