11.4.1. RTL Modules and the HLS Pipeline
HLS libraries allows you to use RTL modules that are written in Verilog, SystemVerilog, or VHDL inside HLS components. The Intel® HLS Compiler integrates the RTL modules into the HLS pipeline architecture.
Consider using HLS libraries in the following situations:
- You want to use optimized and verified RTL modules in HLS components without rewriting the modules as C++ functions.
- You want to implement HLS component functionality that you cannot express effectively in C++.
