PCBWorks PCB design tool is said to enhance workflow collaboration between electrical and mechanical designers. Includes collaboration tools to integrate design data with SolidWorks mechanical design software. Includes schematic capture and PCB layout tools along with an easy-to-use interface that works in tandem with existing mechanical workflows in SolidWorks. Design data between components and mechanical enclosures are linked between electrical and mechanical workflows. Features managed engineering change orders (ECO) process to submit design data changes from SolidWorks to PCBWorks using native SolidWorks files. Board assemblies from PCBWorks can also be opened in SolidWorks with included copper information for deeper analysis and simulation options.

Sigrity Parallel Computing 4-pack and Sigrity System Explorer increase signoff-level printed circuit board extraction accuracy. Parallel Computing 4-pack is a license that allows designers to run parallel computing tasks across four additional computers. System Explorer is an updated power-aware system signal integrity feature that features general purpose topology exploration, enabling power-aware signal integrity and transient power integrity analysis across multiple fabrics. Can enable LPDDR4 sign-off, along with licensing for distributed processing speed-up and multiple tool access. Power-aware system signal integrity feature now supports LPDDR4 analysis with full JEDEC compliance checking, including bit error rate analysis with high-capacity channel simulation for memory interface.
