4.2.2.4. Reset Requirements for Intel® Arria® 10 and Intel® Cyclone® 10 GX Variations

To implement the reset sequence correctly for your RapidIO IP core configured on Intel® Arria® 10 and Intel® Cyclone® 10 GX devices, you must connect the tx_analogreset, tx_digitalreset, rx_analogreset, and rx_digitalreset signals to Transceiver PHY Reset Controller IP core. User logic must drive the following signals from a single reset source:

  • RapidIO IP core reset_n (active low) input signal.
  • Transceiver PHY Reset Controller reset (active high) input signal.
  • TX PLL mcgb_rst (active high) input signal. However, Intel® Arria® 10 and Intel® Cyclone® 10 GX device requirements take precedence. Depending on the TX PLL configuration, your design might need to drive TX PLL mcgb_rst with different constraints.
User logic must connect the remaining input reset signals of the RapidIO IP core to the corresponding output signals of the Transceiver PHY Reset Controller IP core.
Note: In the Transceiver PHY Reset Controller parameter editor, set the value of RX_PER_CHANNEL to 0 for Intel® Arria® 10 and Intel® Cyclone® 10 GX variations.
