C-based Design: High-Level Synthesis with the Vitis HLS Tool

This is an update to the deprecated course C-based Design: High-Level Synthesis with the Vivado HLx Tool.

Receive a thorough introduction to the Vitis™ High-Level Synthesis (HLS) tool. This course covers synthesis strategies, features, improving throughput, area, interface creation, latency, testbench coding, and coding tips. The course focuses on the Zynq® UltraScale+™ MPSoC architecture.

The focus of this course 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
  • Downloading for in-circuit validation
