Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera_arch_re_network_tools.cpp, Line: 883

Environment

  • Intel® Arria® 10 GX FPGA
  • Intel® Stratix® 10 SX SoC FPGA
  • Intel® Quartus® Prime Pro Edition
  • Intel® FPGA SDK for OpenCL™
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    When you compile your OpenCL­™ kernel incrementally using the -incremental command option in your aoc command on the Intel® Programmable Acceleration Card (Rush Creek and Darby Creek). Errors may occur as follows:

    [root@localhost hello_world]# aoc -incremental device/hello_world.cl -o bin/hello_world.aocx

    aoc: Running OpenCL parser....

    aoc: OpenCL parser completed

    aoc: Linking Object files....

    Compiler Warning: Incremental Compilation: the previous compile was not an incremental compile. Performing full recompilation.

    aoc: Optimizing and doing static analysis of code...

    Compiler Warning: addpipe in board_spec.xml is set to 1 which is no longer supported

    Compiler Warning: global memory pipeline stage is now implemented in BSP instead

    aoc: First stage compilation completed successfully.

    aoc: Compiling for FPGA. This process may take several hours to complete.  Prior to performing this compile, be sure to check the reports to ensure the design will meet your performance targets.  If the reports indicate performance targets are not being met, code edits may be required.  Please refer to the Intel FPGA SDK for OpenCL Best Practices Guide for information on performance tuning applications for FPGAs.

    Error (23031): Evaluation of Tcl script a10_partial_reconfig/flow.tcl unsuccessful

    Error: Quartus Prime Shell was unsuccessful. 1 error, 3447 warnings

    Error: Compiler Error, not able to generate hardware

    What’s more, you may find the Internal Error in the quartus_sh_compile.log as follows:

    Internal Error: Sub-system: VPR20KMAIN, File:

    /quartus/fitter/vpr20k/altera_arch_common/altera_arch_re_network_tools.cpp, Line: 883

    Resolution

    This error occurs because Intel® Programmable Acceleration Cards do not support the incrementaln compile feature.   Incremental compile support for Intel® Programmable Acceleration Cards may be added to the oneAPI product in the future, but is not yet confirmed.
