Power Integrity Modeling and Simulation
A robust power delivery network (PDN) is essential for the reliable operation of your high-speed electronics. Our power integrity (PI) simulation services are focused on optimizing your PDN by improving its impedance, allowing you to make informed decisions on Bill of Materials (BOM) and layout changes. We'll help you reduce power supply-induced jitter and model DC drop with electrothermal analysis to ensure your design functions as desired across all operating conditions.
​
We offer complete end-to-end PI modeling services, including everything from the VRM, PCB, package, and die, and we also maintain an extensive library of high-fidelity measurement-based SSAM models. Our PI modeling and simulation services provide the deep visibility required to ensure your PDN remains stable, efficient, and compliant under the most demanding dynamic loads. We guarantee your design meets its specified AC/DC voltage requirements, ensuring compliance and keeping your project on schedule.
The SI/PI Model Library
Unlike standard vendor models that are often encrypted, limited to small-signal analysis, or prone to inaccuracies in the high-frequency domain, our library of measurement-based models provides a unified ecosystem of high-fidelity, validated components.
Curated by our Keysight Certified Experts, these models capture real-world non-linear behaviors and complex transients, allowing you to perform end-to-end system simulations with uncompromised precision
PDN Impedance Optimization & BOM Efficiency
The heart of our PI service is the optimization of your PDN’s impedance. By accurately modeling the frequency-dependent behavior of your decoupling capacitors (including DC bias effects), planes, and vias, we help you identify the precise "sweet spot" for your design.

-
Informed BOM Decisions: We eliminate the guesswork of "over-designing" with unnecessary capacitors. Our analysis allows you to select the optimal quantity and value of components, reducing your Bill of Materials (BOM) costs without sacrificing performance.
​
-
Strategic Layout Changes: We provide actionable feedback on stackup and plane geometries, ensuring that your layout is architected for the lowest possible loop inductance.
DC Drop & Electrothermal Analysis
Modern high-current designs demand more than just a static DC analysis. Signal Edge Solutions provides comprehensive electrothermal modeling to visualize the relationship between current density and temperature rise.​
-
DC IR-Drop: We verify that your silicon receives the required voltage at the pin, accounting for every milliohm of resistance in the path.​
​
-
Thermal Co-Simulation: We ensure your design functions as desired across all operating conditions by modeling how heat affects copper resistivity, preventing localized "hot spots" that can lead to long-term reliability issues or board failure.

Reducing Power-Induced Jitter & Noise
A noisy power rail is the leading cause of timing errors in high-speed data lanes. We specialize in identifying and mitigating power supply induced jitter (PSIJ) by analyzing the interaction between your voltage regulators (VR), voltage regulator modules (VRM), power supplies, and the switching noise of your silicon.
To achieve this, we utilize advanced chip power models (CPMs) to bridge the gap between the PCB and the silicon die. By integrating these high-fidelity models, we can simulate the complex current signatures and parasitic impedances at the die level, allowing us to accurately predict voltage noise and its direct impact on clock and data timing. Our simulations ensure that transient step loads don't translate into signal integrity failures, keeping your eye diagrams open and your bit error rates low across the entire power distribution network.
