Beyond Design: Postmortem Simulation
Often we find that PCB simulation is engaged too late in the design cycle. This results in the simulation process becoming more a post-mortem to uncover what has gone wrong with the design and how it can be resurrected to work as intended.
In my work as a high-speed analyst, I sometimes get called on to fix problems that could have been prevented. However, a total disaster can usually be avoided and final success achieved (providing the conceptual design has been validated).
Ideally, every high-speed design should be exposed to the preventative medicine of pre-layout simulation and proactive stackup and power-delivery optimization.Read the full column here.Editor's Note: This column originally appeared in the February 2013 issue of The PCB Design Magazine.
