Burst Attributes

When On, the address for bursts wraps instead of

an incrementing. With a wrapping burst, when the

address reaches a burst boundary, it wraps back to

the previous burst boundary. Consequently, only the

low order bits need to be used for addressing.

On/OffOnLinewrap burst

When On, memory bursts are aligned to the address

size.

On/OffOnBurst on burst boundaries

only

Miscellaneous

The maximum number of pending reads which can

be queued up by the slave.

N/A1Maximum pending reads

For VHDL BFMs only. Use this option to assign a

unique number to each BFM in the testbench design.

0–10230VHDL BFM ID

Timing

Sets the read latency for fixed-latency slaves. Not

used on interfaces that include the readdatavalid

signal.

N/A0Fixed read latency (cycles)

For slave interfaces that do not use the waitrequest

signal. The read wait time indicates the number of

cycles before the slave responds to a read. The timing

is as if the slave asserted waitrequest for this

number of cycles.

N/A1Fixed read wait time (cycles)

For slave interfaces that do not use the waitrequest

signal. The write wait time indicates the number of

cycles before the slave accepts a write.

N/A0Fixed write wait time (cycles)

Specifies whether to turn on the register stage.On/OffOnRegistered waitrequest

Specifies whether to register incoming signals.On/OffOnRegistered Incoming Signals
