Table 6-1: Key to Annotations

The following table lists the annotations used in this figure.

DescriptionSymbol

The response wait time, which is three cycles. The slave sets this value using the set_interface_

wait_time command.

wt_1

waitrequest is sampled #1 after the falling edge of clk.T

The response wait time for the first read, which is 2 cycles. The slave sets this value using the

set_interface_wait_time command.

wt_2

Signals when read commands were received. The event name is signal_command_received.S

cr_1

–S

cr_2

The response latency for the reads, which is 3 cycles. The slave sets this time using the set_

response_latency command.

rl_1

rl_2

The write response latency for the first write, which is 3 cycles. This is the time between when

the write command is accepted, and the write response is provided by the slave. T

wrl_1

Signals write responses. The event name is signal_response_issued.S

rc_1

rc_3

Signals read responses. The event name is signal_response_issued.S

rc_2

rc_4

Reference number to identify each read or write transaction.T

ID_1

–T

ID_

Reference number to identify write transactions.ID_1, ID_3

Reference number to identify read transactions.ID_2, ID_4
