AR# 44617 System Generator for DSP v13.x - Creating a netlist results in an error, "An internal error occurred in the Xilinx Blockset Library"

Description


When I create a netlist the following error occurs:

"An internal error occurred in the Xilinx Blockset Library."

Please report this error to Xilinx at http://support.xilinx.com as much detail as possible. You may also find immediate help in the Answers Database and other online resources at http://support.xilinx.com

Since it is possible that this internal error resulted from an unhandled usage error in your design, we advise you to carefully check the usage of the block reporting the internal error. If errors persist, we recommend that you restart MATLAB.

*** ERROR ***"

Why am I seeing this error and what debugging steps can I take?

Solution

This error can occur for a variety of reasons. Below are some common examples and the resolution needed:

  • There is a space in the System Generator installation directory.
    • Re-install the System Generator without a space.
    • Avoid a deep installation directory.
  • There is a space in the MATLAB installation directory.
    • Re-install MATLATB without a space.
  • The way MATLAB was invoked.
    • Open up the System Generator via the sysgen token.
    • Ensure that the XILINX environment variable is set and that the PATH includes $XILINX/bin/nt; $XILINX/lib/nt before launching MATLAB.
  • There is an issue with M-Code processing.
    • Check that the "$TEMP" environment variable is accessible and that the temp directory is not full.
  • The cache is too full.
  • License checkout failed.
    • Ensure that the XILINXD_LICENSE_FILE environment variable points to a valid Xilinx.lic file.
