The Cadence® OrCAD® FPGA System Planner provides a complete, scalable solution for FPGA-PCB co-design that allows users to create an optimum correct-by-construction pin assignment. FPGA pin assignment is synthesized automatically based on user-specified, interface-based connectivity (design intent), as well as FPGA pin assignment rules (FPGA-rules), and actual placement of FPGAs on PCB (relative placement). Read more on the FPGA System Planner launch announcement.



Integrating today’s large-pin-count FPGAs – with their many different types of user-configurable pins and assignment rules – extends the time to create optimal pin assignment. Often the assignment is done manually at a pin-by-pin level in an environment that is unaware of the placement of critical PCB components that are connected to FPGAs. Without understanding the impact to PCB routing, FPGA-based design projects are forced to choose between two poor options: live with suboptimal pin assignment, which can increase the number of layers on a PCB design; or deal with several unnecessary iterations at the tail end of the design cycle. Even with several iterations, this manual and error-prone approach can result in unnecessary PCB design re-spins.

The OrCAD FPGA System Planner is integrated with both OrCAD Capture and OrCAD PCB Editor. It reads and creates OrCAD Capture schematics and symbols. In addition, a floorplan view uses existing footprint libraries from OrCAD PCB Editor. Should placement change during layout, pin optimization using FPGA System Planner can be accessed directly from OrCAD PCB Editor.
