A master BFM has configuration fields that you can set with the

set_config()

function to

configure timeout factors, and setup and hold times, and so on. You can also get the value of a
configuration field using the

get_config()

function.

Table 3-2

describes the full list of

configuration fields.

WRITE_ISSUING_
CAPABILITY

The maximum number of outstanding write transactions that
can be issued from the master BFM. This parameter is set
with the Qsys Parameter Editor. See “

Default: 16.

COMBINED_ISSUING_
CAPABILITY

The maximum number of outstanding combined read and
write transactions that can be issued from the master BFM.
