Analyzing the DDR SIMULATION RESULTS

摘要

In the last two articles (June 2016 and July 2016, respectively), we discussed critical signal integrity concerns that engineers face designing the DDR bus, and points to consider while setting up the simulation. We covered how understanding the requirements, and then simulating correctly, increases the odds the board will be functional from the start. This results in reducing the number of spins required for the design, while shortening the time to release. In this third part of the series, we bring the first two parts together by discussing what to look for in the results of the simulation.
