| Intel® Quartus® Prime Standard Edition Version 19.1 (which contains the Intel® HLS Compiler Standard Edition) is not available at the publication date for this document (2019.12.16). | Occasionally check the Download Center for FPGAs for Intel® Quartus® Prime Standard Edition availability. |
| (Windows only) Compiling a design in a directory with a long path name can result in compile failures. |
Compile the design in a directory with a short path name. |
| (Windows only) A long path for your Intel® Quartus® Prime installation directory can prevent you from successfully compiling and running the Intel® HLS Compiler tutorials and example designs. | Move the tutorials and examples to a short path name before trying to run them. |
| When you use the -c command option to have separate compilation and linking stages in your workflow, and if you do not specify the -march option in the linking stage (or specify a different -march option value), your linking stage might fail with or without error messages. | Ensure that you use the same -march option value for both the compilation with the -c command option stage and the linking stage. |
| (Windows only) Pragmas used in templated code are not recognized | Manually specialize the templated code. |
| (Windows only) C++ libraries are not supported | Use C libraries where possible. For example using printf instead of cout. |
| Enqueueing a component with a slave memory might result in a hang in simulation. This hang is an issue in the generated testbench not the component hardware. | If you component uses slave memory, use standard function calls to invoke the component from the testbench. |
(Windows only) When you compile your component, the compiler might issue the following warning: |
Ignore this warning. The executable is expected to work correctly. |
