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/Off

On

Linewrap burst

When On, memory bursts are aligned to the address
size.

On/Off

only

Miscellaneous

The maximum number of pending reads which can
be queued up by the slave.

N/A

1

Maximum pending reads

For VHDL BFMs only. Use this option to assign a
unique number to each BFM in the testbench design.

0–1023

0

VHDL BFM ID

Timing

Sets the read latency for fixed-latency slaves. Not
used on interfaces that include the

readdatavalid

signal.

N/A

0

Fixed 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/A

1

Fixed 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/A

0

Fixed write wait time (cycles)

Specifies whether to turn on the register stage.

On/Off

On

Registered waitrequest

Specifies whether to register incoming signals.

On/Off

Interface Address Type
