When On, waitrequest is asserted high.On/OffOnAssert waitrequest high

When On, read is asserted high.On/OffOnAssert read high

When On, write is asserted high.On/OffOnAssert write high

When On, byteenable is asserted high.On/OffOnAssert byteenable high

When On, readdatavalid is asserted high.On/OffOnAssert readdatavalid

When On, arbiterlock is asserted high.On/OffOnAssert arbiterlock high

When On, lock is asserted high.On/OffOnAssert lock high

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/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 that can be

queued by the slave.

N/A1Maximum pending

reads

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

interfaces that include the readdatavalid signal.

N/A1Fixed read latency

(cycles)

For VHDL BFMs only. Use this option to assign a unique

number to each BFM in the testbench design.

0–10230VHDL 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/A1Fixed 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.

N/A0Fixed write wait time
