Recent Advancements in Circuit Simulation Technology Presented by Xavier Le Goaer Ansoft France
Circuit simulation that supports emerging electronic design trends Trend: Bridging the gap between system to component design Simulation flexibility to handle: • Models from different vendors and description languages (Verilog, Spice, IBIS, TSTONE,…) • Varying levels of model abstraction (physical, circuit to behavioral)
S-parameter algorithms Frequency domain models Time domain models Time Frequency Mixed Frequency-Time Engine What does this mean for circuit simulation?
Direct sparse solution for large circuits • Transient Simulation on digital AND analog section of DDR SDRAM • Nexxim: 3 hours • SimulatorB: 12 hours • Fast Spice: Wrong results
Conclusion Capacity, Speed, Accuracy for increasingly large and complex circuits
