Select Sys PV, then select Analy PV in the pop-up menu.  In the Analy PV menu,
select Board Verification.  In the Board Verification menu, select All Tests.

You can run all tests at one time by selecting All Tests.  To see more details about each test
when troubleshooting failures, you can run each test individually.  This example shows how to
run all tests at once.

When the tests finish, the status for each test shows PASSED or FAILED, and the status for
the All Tests changes from UNTESTED to TESTED.
