1. 1 MULTIBOARD SIMULATION Emmanuel LEROUX Chief Application Engineer

2. 2 of 10 AN EXAMPLE OF A MULTIBOARD SYSTEM

3. 3 of 10 Effects taken into account in the simulation: Reflections (Signal Integrity) Crosstalk Ground Bounce MULTIBOARD SIMULATION

4. 4 of 10 SIMULATION TIME Based on Digital Signal Processing technique Works in Time Domain, with fixed Time step Simple algorithm Speed Robustness Simulation time grows proportionally with complexity of network  permits to simulate a whole system made of PCBs Circuital Simulator: SPRINT
