UM-348 13 - Measuring code coverage Excluding lines/files with a filter file ModelSim SE User’s Manual Exclusion filter files specify files and line numbers or condition and expression udp truth table rows (see below for details) that you wish to exclude from coverage statistics. You can create the filter file in any text editor or save the current filter in the Current Exclusions pane by selecting the pane and then choosing File > Save. To load the filter during a future analysis, select the Current Exclusions pane and select File > Open. Syntax ... [[ ...] [ ...]] | all or begin instance ... ... [[ ...] [ ...]] | all end instance Arguments The name of the file you want to exclude. Required if you are not specifying an instance. The filter file may include an unlimited number of filename entries, each on its own line. You may use environment variables in the pathname. begin instance The name of an instance for which you want to exclude lines. Required if you don’t specify . The filter file may include an unlimited number of instances. The name of the file(s) that compose the instance from which you are excluding lines. Optional. ... A range of line numbers you want to exclude. Optional. Enter the range in "# - #" format. For example, 32 - 35. You can specify multiple ranges separated by spaces. ... A line number that you want to exclude. Optional. You can specify multiple line numbers separated by spaces. all When used with , specifies that all lines in the file should be excluded. When used with , specifies that all lines in the instance and all instances contained within the specified instance should be excluded. Required if a range or line number is not specified. Example control.vhd 72 - 76 84 93 testring.vhd all begin instance /test_delta/chip/bid01_inst src/delta/buffers.vhd 45-46
end instance Default filter file Excluding objects from coverage UM-349 The Tcl preference variable PrefCoverage(pref_InitFilterFrom) specifies a default filter file to read when a design is loaded with the -coverage switch. By default this variable is not set. See "Preference variables located in Tcl files" (UM-540) for details on changing this variable. A file named workingExclude.cov appears in the design directory when you specify exclusions in the GUI. This file remains after quitting simulation. Excluding condition and expression udp truth table lines and rows You can also use exclusion filter files to exclude condition and expression udp truth table rows. Syntax -c | -e { ...} Arguments -c | -e Determines whether to exclude condition (-c) or expression (-e) udp truth table rows. ... The line number containing the condition or expression. The line number and list of row numbers are surrounded by curly braces. A space separated list of row numbers or ranges of row numbers referring to the udp truth table rows that you want excluded. Excluding lines and rows with the coverage exclude command You can use the coverage exclude command (CR-129) for direct exclusion of specific lines in a source file or rows within a truth table. Excluding nodes from toggle statistics To exclude nodes from toggle statistics collection, use the toggle disable command (CR- 281). ModelSim SE User’s Manual
