Hi,
I am building a unit test for a large function that we use, but during report generation (EndOfTestReports) I get the following error.
# ** Fatal: (SIGSEGV) Bad handle or reference.
# Time: 3 ns Iteration: 2 Process: /***_tb/test_ctrl_i/control_p File: /***/OsvvmLibraries/osvvm/ScoreboardGenericPkg.vhd
# Fatal error in Subprogram GotScoreboards at /***/OsvvmLibraries/osvvm/ScoreboardGenericPkg.vhd line 3388
#
# HDL call sequence:
# Stopped at /***/OsvvmLibraries/osvvm/ScoreboardGenericPkg.vhd 3388 Subprogram GotScoreboards
# called from /***/OsvvmLibraries/osvvm/ReportPkg.vhd 132 Subprogram EndOfTestReports
# called from /***/OsvvmLibraries/osvvm/ReportPkg.vhd 182 Subprogram EndOfTestReports
# called from ../i***_tb.vhd 48 Process control_p
The function that causes the error is the “GotScoreboards” function in ScoreboardGeneriPkg.vhd.
My testbench is fairly a simple testbench, where I call the “function under test” with various input parameters and affirm the output values with the reference values, that I generate with an external model (C#). The testbench is written in combinatorial fashion (no clock, no reset, etc.) with a wait 1ps statement after each iteration. Before the report generation there is no error and my testcase comes to an end.
%% 3 ns DONE PASSED ***_tc Passed: 2999 Affirmations Checked: 2999
The testbench doesn’t have any scoreboards, so the “GotScoreboards” function should return false during report generation, but instead I get the above error message.
So, everything is pretty much a standard OSVVM testcase. The only part, that is out of standard is, that I don’t compile the source codes using OSVVM “analyze” API, instead I map a pre-compiled library using “LinkLibrary” API. I don’t see, how this should make a difference, but I wanted to mention it to complete the picture.
Tool List:
OSVVM Script Version: 2024.05b
Simulator Version: ModelSim-2016.04
Has anyone experience a similar error? Could anyone direct me to the source of the error?
Many thanks.
