Modelsim 2021.4 (Windows): How to exclude files from code coverage report
问题
我正在尝试从我的代码覆盖报告中排除特定的VHDL文件，但我无法使其起作用。我的报告总是显示所有可用的文件。
我的工作流程如下：
- 在Modelsim中，我手动编译文件（在GUI中）并选择了代码覆盖选项。
- 测试台脚本如下所示：
# 开始模拟
vsim -coverage work.core_tb -t 1ps
do wave/core_wave.do
view wave -undock
when -label end_of_simulation {end_of_sim == '1'} {echo "模拟结束" ; stop ;
coverage exclude -src ../../../design/hdl/FILE_1.vhd
coverage exclude -src ../../../design/hdl/FILE_2.vhd
coverage exclude -src ../../../design/hdl/FILE_3.vhd
coverage report -output ../../../design/sim/cc_reports/report.txt -srcfile=* -assert -directive -cvg -codeAll};
run -all
wave zoomfull
# 复制模拟结果到本地目录
file copy -force ./_Log.txt ../../../design/sim/sim_reports/safety_core_sim_results.txt
Modelsim识别我的排除（在GUI中）为“待定的排除”。当我手动应用它们（在GUI中）时，“实例覆盖”窗口中显示的文件会按预期减少。但为什么报告不会改变/调整？我做错了什么？
编辑：
似乎在旧版本的Modelsim中可以这样做。
英文:
I am trying to exclude certain vhdl files from my code coverage report, but I can't get it to work. My report always shows all available files.
My workflow is as follows:
- in Modelsim I compile the files manually (in the GUI) with the Code Coverage option.
- the testbench is scripted like this
# Start simulation
vsim -coverage work.core_tb -t 1ps
do wave/core_wave.do
view wave -undock
when -label end_of_simulation {end_of_sim == '1'} {echo "End of simulation" ; stop ;
coverage exclude -src ../../../design/hdl/FILE_1.vhd
coverage exclude -src ../../../design/hdl/FILE_2.vhd
coverage exclude -src ../../../design/hdl/FILE_3.vhd
coverage report -output ../../../design/sim/cc_reports/report.txt -srcfile=* -assert -directive -cvg -codeAll};
run -all
wave zoomfull
# Copy simulation results to local directory
file copy -force ./_Log.txt ../../../design/sim/sim_reports/safety_core_sim_results.txt
Modelsim recognizes my exclusions (in the GUI) as "pending exclusions". When I apply them manually (in the GUI), the files shown in the "Instance coverage" window are reduced as intended. But why does the report not change/adjust? What am I doing wrong?
Edit:
It seems that it worked that way with an older Modelsim Version.

解决方案是停用“两步排除”选项。要停用它，请转到Modelsim菜单：
工具 > 覆盖配置 并禁用‘Two-Step Exclusions’菜单选项。
或者可以使用以下TCL命令：
coverage configure -2stepexclusion off
当“Two-Step Exclusions”选项处于活动状态时，意味着所有应用的排除都会首先进入“待处理排除”选项卡。
英文:
The solution is to deactivate ‘Two-Step Exclusions’ option. To deactivate it go to the Modelsim menu:
Tools > Coverage Configuration and disable ‘Two-Step Exclusions’ menu option.
Alternatively the following TCL command could be used:
coverage configure -2stepexclusion off
When the ‘Two-Step Exclusions’ option is active it means that any applied exclusions always go to the ‘pending exclusions’ tab first.
