Burst Attributes
When On, the address for bursts wraps instead of
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
are used for addressing.
On/Off
On
Linewrap burst
When On, memory bursts are aligned to the address size.
On/Off
On
Burst on burst
boundaries only
Miscellaneous
The maximum number of pending reads that can be
queued by the slave.
N/A
1
Maximum pending
reads
Sets the read latency for fixed-latency slaves. Not used on
interfaces that include the
readdatavalid
signal.
N/A
1
Fixed read latency
(cycles)
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
For master interfaces that do not use the
waitrequest
signal. The read wait time indicates the number of cycles
before the master responds to a read. The timing is as if
the master asserted
waitrequest
for this number of
cycles.
N/A
1
Fixed read wait time
(cycles)
For master interfaces that do not use the
waitrequest
signal. The write wait time indicates the number of cycles
before the master accepts a write.
