HyperLynx Signal Integrity/Power Integrity (SI/PI) adds power-aware SI simulation capabilities for accurate modeling and signal performance of high-speed parallel links such as DDR3 and DDR4. Is for high-speed printed circuit board designs. Power-Aware IBIS v5.0 modeling reportedly ensures accurate simulation of simultaneous switching noise and power effects of timing and signal integrity. DDRx Wizard supports the latest JEDEC standards to verify all DDR and LPDDR memory types. Integrated S-parameter extraction and simulation is reportedly accurate and 5 to 10 times faster. High-performance DC drop/thermal co-simulation predicts voltage drop, high current areas, and temperature changes. Addresses high-speed system design problems throughout design flow. Provides tools for pre- and post-layout signal integrity, timing, crosstalk and power integrity analysis to generate accurate simulation results to prevent design re-spins. Models supply currents, including pre-driver effects, switching slowdown due to sagging supply voltage, and better buffer capacitance modeling.
