Cadence Design Systems has added LPDDR4 support and a topology explorer to its Sigrity lineup for signal and power integrity analysis of PCB-based designs, as well as more flexible licensing options.
The addition of the Sigrity System Explorer provides general-purpose topology exploration, enabling power-aware signal integrity and transient power integrity analysis across multiple fabrics. Power-aware system signal integrity now supports LPDDR4 analysis with full JEDEC compliance checking, including bit error rate analysis and high-capacity channel simulation for the memory interface.
In terms of licensing, Cadence has added a parallel-computing four-pack that allows designers to run parallel computing tasks across four additional computers for faster turnaround times on simulation and extraction.
The company has also introduced several product bundles, aimed at smaller analysis teams. They include a combined license for signal- and power-integrity base products where a single user is responsible for both tasks. There is also a combined system signal-integrity license for both serial link and parallel bus analysis, when a single user is responsible for both memory interfaces and SerDes interfaces.
