Brocade Communications Systems, as an innovative networking HW and SW technology corporation, understand the value of being able to perform deep analysis and have sufficient visibility of the data and activity in their network. The same goes for debug of their complex silicon projects. We will show how our design verification team moved up to Mentor's Visualizer™ Debug Environment as the design entered a complex phase of development and we required a robust, stable, feature-rich debugging tool. The team looked for a debug solution that had a small memory footprint, tight simulator integration, high capacity and performance. We show how Visualizer solved those problems and provides post-simulation visibility of class member values as if running live on the simulator.
