CR-60 ModelSim Commands ModelSim EE/SE Command Reference

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> [ -keep ]

Arguments

Specifies the file containing data to reload. Required. This file should be the output of a

previous COVERAGE REPORT -lines command.

-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.
