Course Description

This course provides a thorough introduction to the Vitis™ High-Level Synthesis (HLS) tool. The focus is on:

  • Converting C/C++ designs into RTL implementations.
  • Learning the Vitis HLS tool flow.
  • Creating I/O interfaces for designs by using the Vitis HLS tool.
  • Applying different optimization techniques.
  • Improving throughput, area, latency, and logic by using different HLS pragmas/directives.
  • Exporting IP that can be used with the Vivado® IP catalog.
  • Migrating designs from the classic Vitis HLS tool to the Vitis Unified IDE.
