WebAug 29, 2024 · Actually UVM provides some built-in tests (register access, reset test , bit bash test, ...), and provides some variables (i.e NO_REG_TESTS) to disable these tests for a given register. So my interpretation was to use "testable" field to disable these UVM tests, but I still have some doubts it is not the good interpretation.
