Slave Assertions
The slave BFM performs protocol error checking via built-in assertions.
AXI4 _ CONFIG_MAX_OUTSTANDING_WR Configures the maximum number of
outstanding write requests from the
master that can be processed by the
slave. The slave back-pressures the
master by setting the signal
AWREADY=0b0 if this value is
exceeded.
Default = 0.
AXI4 _ CONFIG_MAX_OUTSTANDING_RD Configures the maximum number of
outstanding read requests from the
master that can be processed by the
slave. The slave back-pressures the
master by setting the signal
ARREADY=0b0 if this value is
exceeded.
Default = 0.
AXI4 _ CONFIG_NUM_OUTSTANDING_WR_
PHASE
Holds the number of outstanding write
phases from the master that can be
processed by the slave.
Default = 0.
AXI4 _ CONFIG_NUM_OUTSTANDING_RD_
PHASE
Holds the number of outstanding read
phases to the master that can be
processed by the slave.
Default = 0.
