Error (13224): Verilog HDL or VHDL error at <kernel_filename>.v: ansi port p_avm_printf_addrhello_world_enable cannot be redeclared

Environment

    Intel® Quartus® Prime Pro Edition
    Intel® FPGA SDK for OpenCL™ Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

In the Intel® FPGA SDK for OpenCL™ version 17.1, you may see this error while calling a printf () inside a kernel with attribute num_compute_units().

 

Resolution

To avoid this error, perform either of the following actions:

  • manually replicate printf calls inside the kernel 
  • replace printf with channel calls that send data to a non-compute-id kernel which in turn performs the printfs.

This is fixed in the Intel FPGA SDK for OpenCL version 18.0
