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

Burst on burst boundaries
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
