Growing SoC complexity, an increasing amount of embedded software, and the high cost of emulation systems have driven the need for custom prototyping. However, there is significant complexity of designing boards with multiple FPGAs. Cadence Allegro FPGA System Planner was designed to overcome the challenges with multi-FPGA board design. It is designed to be used in combination with commercial tools available for RTL partitioning, FPGA design, and board design. This application note will walk you through a complete FPGA board for ASIC prototyping.
