A slave BFM has configuration fields that you can set with the
function to
configure timeout factors, setup and hold times, and so on. You can also get the value of a
configuration field via the
function.
describes the full list of configuration fields.
WRITE_ACCEPTANCE_
CAPABILITY
The maximum number of outstanding write transactions
that can be accepted by the slave BFM. This parameter is
set with the Qsys Parameter Editor. See “
Default: 16.
COMBINED_ACCEPTANCE_
CAPABILITY
The maximum number of outstanding combined read and
write transactions that can be accepted by the slave BFM.
This parameter is set with the Qsys Parameter Editor. See
