Register Field Mirroring

[mbowler]

I have a register R with several fields, A and B. R is read-only and volatile as it is a status register. I am finding that a read of R does not seem to update the mirrored values of the fields. Is it supposed too? If not how do I get a single bus read transaction to update all the fields in a register.

e.g.

R.read(stat, rd_data)

R.A.get(aval);

R.B.get(bval);

R.get(rval);

With the above code,

- rval and rd_data match and are as expected.

- aval and bval contain the reset value.

What am I doing wrong here?

Thanks,

Michael

Try setting auto predict on the map that the register is reading through (the default map, since you didn't specify one):

my_reg_block.my_map.set_auto_predict(1);

Also, make sure that the status of the read was UVM_IS_OK.

I think that will do it.

Ooops. My fault... my code should be:

aval = R.A.get();

bval = R.B.get();

Sometimes I wish SV had stricter type checking.
