I am a beginner in Quartus, i have a c code i want to convert it to vhdl code, can i use HLS compiler?

Hi

The HLS compiler can convert the HLS targeted C/C++ code to the RTL.

You can also convert C files for hardware acceleration to HDL using NIOS II ,C2H compiler also.

But to be exact , if you have a general purpose C program , it will not be 1:1 converted to VHDL using Quartus.

The conversion happens to support the specific functions at the target hardware.

Thanks and Regards
