Parameter Type Description

pll_self_reset_on_loss_lock String The values are ON and OFF. If omitted, the

default value is OFF. When this parameter is

enabled, the PLL is reset when it loses lock. This

parameter is valid for Cyclone III, Cyclone IV,

Stratix III, and Stratix IV devices when the

implement_in_les parameter is set to ON.

port_rx_channel_data_align String Edge-sensitive bit-slip control signal. Each

rising edge on this signal causes the data re-

alignment circuitry to shift the word boundary

by one bit. The minimum pulse width require‐

ment is one parallel clock cycle. There is no

maximum pulse width requirement. Determines

if the rx_channel_data_align port is used or

unused. The values are PORT_USED, PORT_

UNUSED, and PORT_CONNECTIVITY. When set to

PORT_USED, the rx_channel_data_align port

is used. When set to PORT_UNUSED, the rx_

channel_data_align port is unused. When set

to PORT_CONNECTIVITY, the Quartus II software

checks the connectivity of the rx_channel_

data_align port to determine port usage. If

omitted, the default value is PORT_

CONNECTIVITY.

port_rx_data_align

String Determines if the rx_align_data_reg port is

used or unused. The values are PORT_USED,

PORT_UNUSED, and PORT_CONNECTIVITY. When

set to PORT_USED, the rx_align_data_reg port

is used. When set to PORT_UNUSED, the rx_

align_data_reg port is unused. When set to

PORT_CONNECTIVITY, the Quartus II software

checks the connectivity of the rx_align_data_

reg port to determine port usage. If omitted, the

default value is PORT_CONNECTIVITY.

registered_data_align_input String Specifies whether the rx_align_data_reg port

is registered. The values are ON and OFF. If

omitted, the default is ON. Only available for

Stratix and Stratix GX devices.

registered_output String Indicates whether the rx_out[] port should be

registered. The values are ON and OFF. If

omitted, the default is ON. If the registered_

output parameter is set to OFF, you should pre-

the receiver.
