Simulation: the need for speed: establishing selection criteria can help determine the best simulation model for a specific task.
The jitter specifications for SerDes (Serializer/Deserializer) interfaces keep getting smaller, and the timing margins for memory interfaces, like DDR3, keep shrinking until they are almost gone. As design margins shrink, PCB designers need to be able to predict how designs are going to behave in order to avoid costly re-spins and rework.
The goal of any signal integrity simulation is to validate that the interfaces on the PCB design will meet timing and noise margin specifications. By using simulations at the right times in a PCB design flow, costly board spins and rework can be avoided, as illustrated in FIGURE 1. Simulations give the designer a window into what is happening in a system. A typical pro...See the full content of this document
