Table 4-2: LPM_MULT Parameters - General2

This table lists the IP core parameters applicable to MAX 10 devices.

GUI Parameter Parameter Condition Value Description

Does the ‘datab’ input

bus have a constant

value?

— —

• No

• Yes, the value

is []

You can specify the

constant value of the

‘datab’ input bus, if any.

Which type of multipli‐

cation do you want?

LPM_

REPRESENTATI

—

• Unsigned

• Signed

Specifies the type of

multiplication

performed.

Which multiplier

implementation should

be used?

DEDICATED_

MULTIPLIER_

CIRCUITRY

—

• Use default

implementa‐

tion

• Use the

dedicated

multiplier

circuitry (Not

available for all

families)

• Use logic

elements

Specifies the multiplier

implementation.

Table 4-3: LPM_MULT Parameters - Pipeling

This table lists the IP core parameters applicable to MAX 10 devices.

GUI Parameter Parameter Condition Value Description

Do you want to

pipeline the function?

LPM_PIPELINE —

• No

• Yes, I want

output

latency of []

clock cycles

You can add extra

latency to the outputs,

if any.

Create an ‘aclr’

asynchronous clear

port

— Do you want to

pipeline the

function? = Yes,

I want output

latency of []

clock cycles

On or off Specifies asynchronous

clear for the complex

multiplier. Clears the

function asynchro‐

nously when aclr port

is asserted high.

Create a ‘clken’ clock

enable clock

— Do you want to

pipeline the

function? = Yes,

I want output

latency of []

clock cycles

On or off Specifies active high

clock enable for the

clock port of the

complex multiplier

What type of optimiza‐

tion do you want?

MAXIMIZE_

SPEED

—

• Default

• Speed

• Area

You can specify if the

type of optimization is

determined by Quartus

II, speed, or area.
