    Dear Accellera developers, I have been working with the register model since some weeks. I have tried to understand how the adapters were supposed to be used for all the possible combinations of accesses and register definitions. After those weeks I still have some questions. Lets assume we have a register of 32bits with 3 fields. The databytes per address granularity is 1 databyte per increment of address. In other words, each address increment corresponds to one data byte written . That means that a 32bit register comprises 4 address per register. We have a protoc

    In uvm_reg_map::do_bus_read() task, after the call to adapter.bus2reg() function, do_bus_read() function checks for any Xs in data field. Code from uvm_reg_map: uvm_reg_bus_op rw_access; uvm_reg_data_logic_t data; data = rw_access.data & ((1<<bus_width*8)-1); rw.status = rw_access.status; if (rw.status == UVM_IS_OK && (^data) === 1'bx) rw.status = UVM_HAS_X; Here, rw_access.data is of type "bit" and is assigned to data which is of type "logic". and then data is checked for Xs. But, as rw_access.data is "bit" type, it will
