  • Resets do not propagate to GT Quad when the gtpowergood from GT Wizard is low
  • Tie the rate port of the GT Wizard to 0 until gtpowergood is high
  • When GT Reset is asserted to the GT Wizard, INTF*_rst_tx_done_out and INTF*_rst_rx_done_out from the GT Wizard indicate the reset sequence completed successfully
  • When the rate port changes on the GT Wizard, INTF*_rst_tx_done_out and INTF*_rst_rx_done_out from the GT Wizard indicate the rate change is successful
  • Assert the rate change only when the INTF*_rst_tx_done_out and INTF*_rst_rx_done_out from the GT Wizard are high
  • Assert the GT Reset only when the INTF*_rst_tx_done_out and INTF*_rst_rx_done_out from the GT Wizard are high
  • Do not assert GT Reset and rate change at the same time
