Using Signal Aliases

Using aliases allows testers to add flexibility to their tests w.r.t expected interface changes of the model under test, addressing signals using arbitrary signal names or access to bus and matrix signal elements.

An alias in Arttest is a mapping between an user defined identifier and a signal from the model under test.

Use an alias mapping to

  • Test using arbitrary signal names in the test
  • Limit required changes of the tests to changes in the mapping, in case signal names of the interface being tested change
  • Access individual elements of a matrix or bus signal in the test
