tx_bonding_clocks_ch3[5:0]

Input

Transceiver channel TX input clocks for RapidIO lane 3. This signal is
available only in Arria 10 4x variations. Each transceiver channel that
corresponds to a RapidIO lane has six input clock bits. The bits are
expected to be driven from a TX PLL. Refer to

“External Transceiver PLL”

on page 2–7

.

tx_analogreset

[-1:0]

Input

These signals are documented in the

Arria 10 Transceiver PHY User

Guide

.

You must connect these signals to an Altera Transceiver PHY Reset
Controller IP core, which implements the appropriate reset sequence for
the device. Connect each signal to the corresponding signal in the
Transceiver PHY Reset Controller IP core.

These signals are available only in Arria 10 IP core variations.

Notes to

Table 5–8

:

(1) You connect this clock inside the Qsys tool. If you connect it to an external clock, a port with the name of that external clock is added to your

Qsys system and this clock is connected to it.

(2) Refer to

“Instantiating Multiple RapidIO IP Cores” on page 2–10

for information about how to successfully combine multiple high-speed

transceiver channels—whether in two RapidIO IP core instances or in a RapidIO IP core and in another component—in the same transceiver
block.

Description

reconfig_clk_ch0

Input

Arria 10 dynamic reconfiguration interface clock for the transceiver
channel configured for RapidIO lane 0.

reconfig_reset_ch0

Input

Arria 10 dynamic reconfiguration interface reset for the transceiver
channel configured for RapidIO lane 0.

reconfig_waitrequest_ch0

Output

Arria 10 dynamic reconfiguration slave wait request for the
transceiver channel configured for RapidIO lane 0. The RapidIO IP
core uses this signal to stall the requestor on the interconnect.

reconfig_read_ch0

Input

Arria 10 dynamic reconfiguration slave read request for the
transceiver channel configured for RapidIO lane 0.

reconfig_write_ch0

Input

Arria 10 dynamic reconfiguration slave write request for the
transceiver channel configured for RapidIO lane 0.

reconfig_address_ch0[9:0]

Input

Arria 10 dynamic reconfiguration slave address bus for the
transceiver channel configured for RapidIO lane 0. The address is a
word address, not a byte address.

reconfig_writedata_ch0[31:0]

Input

Arria 10 dynamic reconfiguration slave write data bus for the
transceiver channel configured for RapidIO lane 0.

reconfig_readdata_ch0[31:0]

Output

Arria 10 dynamic reconfiguration slave read data bus for the
transceiver channel configured for RapidIO lane 0.
