This is particularly important for the latest high-speed DDR3/4 memory devices. The new "relative signal propagation" feature of the ICD Cascade plan not only allows you to race the long bus, but this step requires a further complete match by automatically simulating the appropriate length of delay required. qq:16264558 tel:13963782271Icd. stackup.planner.v
