Parameter Legal Values Description

What should the memory block type be? Auto, M4K, M9K,

M144K, M10K,

M20K

Specifies the memory block

type. The types of memory

block that are available for

selection depends on your

target device.

Set the maximum block depth to Auto, 32, 64, 128,

256, 512, 1024, 2048,

4096

Specifies the maximum block

depth in words.

What clocking method would you like to use?

• Single clock

• Dual clock: use

separate ‘input’

and ‘output’

clocks

Specifies the clocking

method to use.

• Single clock—A single

clock and a clock enable

controls all registers of

the memory block

• Dual clock (Input and

Output clock)—The

input clock controls the

output clock controls the

data-out registers. There

are no write-enable, byte-

enable, or data-in

registers in ROM mode.

Parameter Settings: Regs/Clken/Aclrs

Which ports should be registered? ‘q’ output port On/Off Specifies whether to register

Use clock enable for

port A output

registers

On/Off Specifies whether to use

clock enable for port A

output registers.

Create an

‘addressstall_a’ input

port.

On/Off Specifies whether to create a

addressstall_a input port.

You can create this port to

act as an extra active low
