Prototype:
bit [AV_NUMSYMBOLS-1:0] get_response_byte_enable(int
index) .
Arguments: index .
Returns: bit[AV_NUMSYMBOLS-1:0] .
Description: Returns the value of the byte enables in the response descriptor that has
been removed from the response queue. Each cycle of a burst response is
addressed individually by the specified index.
Prototype: bit [AV_BURSTCOUNT_W-1:0]get_response_burst_size () .
Arguments: None.
Returns: bit[AV_BURSTCOUNT_W-1:0] .
Description: Returns the size of the response transaction burst count in the response
descriptor that has been removed from the response queue.
Prototype: bit [AV_DATA_W-1:0] get_response_data(int index) .
Arguments: index .
Returns: bit[AV_DATA_W-1:0] .
Description: Returns the transaction read data in the response descriptor that has been
removed from the response queue. Each cycle in a burst response is
addressed individually by the specified index. In the case of read
responses, the data is the data captured on the
avm_readdata interface
pin. In the case of write responses, the data on the driven avm_writedata
pin is captured and reflected here.
Prototype: int get_response_latency(int index) .
Arguments: index .
Returns: int .
Description: Returns the transaction read latency in the response descriptor that has
been removed from the response queue. Each cycle in a burst read has its
own latency entry.
Prototype: int get_response_queue_size() .
Arguments: None.
Returns: automatic int .
Description: Queries the response queue to determine number of response descriptors
currently stored in the BFM. This is the number of responses the test
program can immediately remove from the response queue for further
processing.
