CR-8000 System Planner has enhanced hierarchical and module-based system design capabilities. Optimizes interconnection of system boards created by multiple users. Design Gateway feature allows constraints design and reuse by multiple team members. Collaborative constraints design and reuse help reportedly reduce design time and improve design efficiency. Constraint information for each functional block is now directly associated with block circuit. Constraints can now be managed at the block level, and constraints associated with reuse circuits are reusable. CR-8000 Design Force and DFM Elements output to IPC-2581B. Interfaces support system design with Simulink and boundary scan with JTAG integration to check original design intent and quality achieved. Information shared concurrently among all engineering disciplines from circuit design to layout.
