controlling field for bus transaction from reg sequence

Recommended Posts


what is the best way of controlling bus transaction related fields which are not available in reg sequence.

for example register access to a particular register can be secure/unsecure and previleged/unprevileged.

I would like to control these transaction field from reg sequence, what is the best of doing it ?

the path would be to define a new object deriving from uvm_object holding the additional properties. a configured instance can then be passed via the <uvm_reg>.write/read/update/mirror function in the "extension" argument. in the reg-to-bus adapter.reg2bus() translation stage you can refer to the passed object as "get_item().extension" and you can adjust the properties of your low level sequence.
