7.4. Transceiver Level Connections in the Testbench

The testbench for Intel® Arria® 10 , Intel® Stratix® 10 and Intel® Cyclone® 10 GX variations demonstrates one method to connect the reset controller, the TX PLL, and the RapidIO II IP core to each other.

Signal Direction Connection Requirements
pll_powerdown Input Connect pll_powerdown to the pll_powerdown[0] output port of the reset controller.

This signal is available in Arria® V, Arria® V GZ, Cyclone® V, and Stratix® V variations only.

pll_refclk0 Input Drive the PLL pll_refclk0 input port and the RapidIO II IP core tx_pll_refclk signal from the same clock source.
pll_locked Output Connect pll_locked to the pll_locked[n] input signal of the reset controller, for each transceiver channel n that connects to the RapidIO link.
pll_cal_busy Output Drive the pll_tx_cal_busy input signal of the reset controller.
mcgb_rst 47 Input Drive mcgb_rst from the system reset signal.
tx_bonding_clocks [6N-1:0] where N is the number of lanes in the IP core variation Output Connect the TX PLL tx_bonding_clocks output signal bits [6z+5:6z] to the RapidIO II IP core tx_bonding_clocks_chz input signal to RapidIO lane z.
47 This signal is unavailable while using Intel® Stratix® 10 devices.
