11.3. Creating Objects From HLS Code
You can create a library from object files from your HLS source code. An HLS-based object file contains code for CPU execution (testbench and emulation) and FPGA execution. A library can contain multiple object files.
You can create object files for use with different Intel high-level design tools from the same HLS source code.
Depending on the target high-level design tool, your source code might require adjustments to support tool-specifc data types or constructs.
Intel® HLS Compiler
No additional work is needed in your HLS source code when you use the code to create objects for Intel® HLS Compiler libraries.
Intel® FPGA SDK for OpenCL™
The Intel® FPGA SDK for OpenCL™ supports language constructs that are not natively supported by C++. Your code might need modifications to support those constructs.
The Intel® HLS Compiler supports a limited set of OpenCL* language constructs through the ocl_types.h header file. For details, review Supported OpenCL Language Constructs.
To create an object from your HLS code that targets the Intel® FPGA SDK for OpenCL™ , you must have the Intel® FPGA SDK for OpenCL™ Pro Edition installed. The version of the SDK must be the same as your version of Intel® HLS Compiler.
