The C2H Compiler Regenerates an Accelerator Unnecessarily

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    The C2H Compiler might regenerate an accelerator even when the accelerated function is unchanged. This problem can result from changes to files included by the C file containing the accelerated function. The C2H Compiler fails to check that the generated hardware description language (HDL) matches the previously generated HDL causing the system to be regenerated.

    Resolution

    To avoid this issue move the accelerator-specific information from the include file to a separate include file. This Workaround prevents regeneration of the system when the HDL is unchanged.
