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. WebDec 3, 2013 · do_check() (when called from write() of uvm_predictor) is passed get_mirrored_value() as the expected value and reg_item.value[0] as the actual value, ie the expected value will be the the combined mirror values of the fields, while the actual value will be combined read-back of the bus transactions covering the register.
