FPGA-based prototypes deliver high value to a SoC development organization by providing multi-megahertz processing performance, real world I/O connectivity, and portability for distribution to software developers or field testing scenarios. The prototypes deliver operational systems running fast enough to make embedded software development and hardware/software validation feasible. Teams that have adopted FPGA-based prototyping realize months in shortened schedules and a more efficient and parallel hardware/software engineering methodology.
To fully realize the potential of these systems and maximize the return on investment from prototyping systems, development teams are taking advantage of advanced data exchange links beyond traditional JTAG. High-bandwidth physical links like PCI Express (PCIe) over Cabling allow the prototype to communicate with custom user applications for system control and monitoring. With a transaction-level interface to a SystemC/TLM virtual prototype, a new class of hybrid prototype is possible that leverages the strengths of both hardware and software-based prototyping methods.
