coverage reload

The coverage reload command is used to seed the coverage statistics with the output of a previous coverage report command. This allows you (for example) to gather statistics from multiple simulation runs into a single report.

Syntax

coverage reload

<filename> [-incremental] [-keep]

Arguments

<filename>

Specifies the file containing data to reload. Required. This file should be the output of a previous coverage report -lines command.

-incremental

Adds loaded coverage data to current data. Optional. Without this switch, loading coverage data overwrites existing data.

-keep

By default, source files listed in the file being reloaded that do NOT exist in the current design will have their coverage data discarded. By specifying the -keep option, the data will be kept, even though it does not correspond to any file or line in the current design.

The coverage reload command allows the accumulation of coverage statistics for multiple simulation invocations.

By doing a coverage report -lines at the end of each simulation, and then a coverage reload -keep right at the start of each subsequent invocation of the simulator, one can accumulate coverage data for a suite of different designs.
