2.2.1. Considerations for the Intel® Hyperflex™ FPGA Architecture

The Intel® Hyperflex™ FPGA architecture and the Hyper-Retimer require a review of the best design practices to achieve the highest clock rates possible.

While most common techniques of high-speed design apply to designing for the Intel® Hyperflex™ architecture, you must use some new approaches to achieve the highest performance. Follow these general RTL design guidelines to enable the Hyper-Retimer to optimize design performance:

  • Design in a way that facilitates register retiming by the Hyper-Retimer.
  • Use a latency-insensitive design that supports the addition of pipeline stages at clock domain boundaries, top-level I/Os, and at the boundaries of functional blocks.
  • Restructure RTL to avoid performance-limiting loops.
