Description

PORT_OUTPUT_IS_OVERFLOW String No Specifies port usage. Values are

PORT_UNUSED and PORT_USED.

When the value is set to PORT_

USED, output pin overflow is

added. If omitted, the default

value is PORT_UNUSED.

PORT_CHAINOUT_SAT_IS_OVERFLOW String No Specifies port usage. Values are

PORT_UNUSED and PORT_USED.

When the value is set to PORT_

USED, output pin chainout_sat_

overflow is added. If omitted,

the default value is PORT_UNUSED.

SCANOUTA_REGISTER String No Specifies the clock source for the

scanouta data bus registers.

Values are UNREGISTERED,

CLOCK0, CLOCK1, CLOCK2, and

CLOCK3. If omitted, the default

value is UNREGISTERED.

SCANOUTA_ACLR String No Specifies the asynchronous clear

source for the scanouta data bus

registers. Values are NONE, ACLR0,

ACLR1, ACLR2, and ACLR3. If

omitted and SCANOUTA_REGISTER

is used, the default value is ACLR3.

CHAINOUT_REGISTER String No Specifies the clock source for the

chainout mode result register.

This is an additional stage after

the second adder. Values are

UNREGISTERED, CLOCK0, CLOCK1,

CLOCK2, and CLOCK3. If omitted,

the default value is CLOCK0.

CHAINOUT_ACLR String No Specifies the asynchronous clear

for the chainout mode result

stage after the second adder.

Values are NONE, ACLR0, ACLR1,

ACLR2, and ACLR3. If omitted and

CHAINOUT_REGISTER is used, the

default value is ACLR3.
