    Hi,
    I’m having an issue with OSVVM in XSIM. I have a procedure that uses a CovPType as inout parameter, similar to the CompareBins procedure in CoveragePkg. XSIM gives me this error for my procedure as well as for the CompareBins procedure of the CoveragePkg:

    FATAL_ERROR: Vivado Simulator kernel has discovered an exceptional condition from which it cannot recover. Process will terminate.

    Has anyone a workaround for this? Seems to be a bug in XSIM. Other simulators work just fine, e.g. NVC or commercial ones.

    Thanks
    Matthias

    OK, I just checked, this seems to be a regression in XSIM. It works in 2024.2.2 as well as 2025.1.
