Operational Transaction Fields
read_or_write An enumeration to hold the read or write control flag. The
types of read_or_write are:
AXI4 _TRANS_READ
AXI4 _TRANS_WRITE
address_valid_delay An integer to hold the delay value of the address channel
AWVALID and ARVALID signals (measured in ACLK
cycles) for a read or write transaction, respectively.
data_valid_delay An integer to hold the delay value of the data channel WVALID
and RVALID signals (measured in ACLK cycles) for a read or
write transaction, respectively.
write_response_valid_delay An integer to hold the delay value of the write response channel
BVALID signal (measured in ACLK cycles) for a write
transaction.
address_ready_delay An integer to hold the delay value of the address channel
AWREADY and ARREADY signals (measured in ACLK
cycles) for a read or write transaction, respectively.
data_ready_delay An integer to hold the delay value of the data channel
WREADY and RREADY signals (measured in ACLK cycles)
for a read or write transaction, respectively.
write_response_ready_delay An integer to hold the delay value of the write response channel
BREADY signal (measured in ACLK cycles) for a write
transaction.
gen_write_strobes Automatically correct write strobes flag. Refer to Automatic
Generation of Byte Lane Strobes for details.
operation_mode An enumeration to hold the operation mode of the transaction.
The two types of operation_mode are:
AXI4 _TRANSACTION_NON_BLOCKING
AXI4 _TRANSACTION_BLOCKING
write_data_mode An enumeration to hold the write data mode control flag. The
types of write_data_mode are:
AXI4 _DATA_AFTER_ADDRESS
AXI4 _DATA_WITH_ADDRESS
transaction_done A bit to hold the done flag for a transaction when it has
completed.
