    Critical Issue

    Description

    An issue with the JTAG Avalon master can cause simulation to fail with the following error message:

    Error-[UST] Undefined System Task Call submodules/altera_pli_streaming.v, 53 Undefined System Task call to ‘’.
    Resolution

    The workaround for this issue is to remove the altera_pli_streaming file from the list of files used in the simulation if the programming language interface (PLI) is turned off.
