Empyrean Patron® is a transistor-level power integrity analysis solution featuring advanced analysis capabilities for dynamic EM/IR, self-heating, and multi-state EM/IR. 

Its intuitive visual GUI, coupled with fast layout back-annotation, simplifies environment setup and accelerates root-cause analysis for power integrity violations.  Compared to the solutions previously deployed in our flow, Patron delivers significantly shorter analysis turnaround times. Notably, as chip size and design complexity increase, the performance advantage becomes even more pronounced.

In real projects, engineers can rapidly import Patron results into our silicon debug and inspection environment, enabling efficient result highlighting and sorting. The unique Probe-On function allows users to instantly inspect detailed EM/IR values at points of interest, streamlining the review process.  

Compared with our previous tools, Patron's powerful back-annotation capabilities significantly reduce the time engineers spend iterating between violation analysis and physical layout correlation.  In terms of technical support, the product experts from Empyrean provide timely and efficient application assistance whenever needed.

WillSemi leverages Empyrean Polas® as its reliability analysis solution, ensuring a high level of robustness and reliability for discrete devices and power management ICs (PMICs).

"As design complexity continues to increase, power device design scenarios have become increasingly sophisticated. In addition to single-transistor structures, various stacked-transistor configurations have become an integral part of modern designs. 

Empyrean Polas® provides valuable guidance for RDS(on) and electromigration (EM) analysis of these complex structures. The tool presents RDS(on) results by net and layer, PAD current distribution for EM analysis, and comprehensive EM/IR-drop visualizations, helping engineers identify interconnect, PAD placement, and reliability issues.  It also helps reduce design redundancy while maintaining reliability and provides insights for layout optimization to achieve smaller die sizes."

"Benefiting from abundant experiences and test data, MPS has been leading the CMOS power supply technology in the world. With help from Empyrean's Polas power layout analysis solution, we were able to analyze and build the required reliability into the design prior to tape out. We also chose Empyrean for their excellent support on a variety of customized features."

"During the final stage of chip design, short troubleshooting is often a painful task. With Empyrean Skipper, our engineers can quickly pinpoint the shorts on the layout with ease. 

Mixed-signal designs usually take a long time to simulate because digital blocks must first be flattened into transistor-level circuit and then simulated using SPICE. With Empyrean ALPS, we can complete these simulations several times faster than our traditional solutions."

"Recent advanced designs have complicated clock structures to achieve higher performance and lower power consumption, which makes it hard to detect the clock problems in a short period of time. Empyrean ClockExplorer can help to report Clock KPI in various design stages such as pre-Place, pre-CTS, and post-CTS, with helpful numerical scores to indicate the quality of clock structure. This has enabled us to avoid issues that could have arisen in the later stages and enhance our product quality. "

"Building a seamless mixed-signal IC design flow is critical to advancing our design capabilities. By combining TowerJazz's PDK with Empyrean's comprehensive analog design EDA solution, we have significantly improved our design and verification efficiency," said O2Micro, a leading global power management IC company. 

"Another important reason for choosing Empyrean is its ability to provide outstanding technical support to our teams around the world."
