Table 4.  Signal Tap Debug Signals
Signal Description
Common Debug Signals for All Design Examples
o_src_rs_req Request signal to GTS Reset Sequencer.
i_src_rs_grant Grant signal from GTS Reset Sequencer.
o_tx_pll_locked Indicates that the TX serdes PLLs are locked.
o_rst_ack_n Active-low asynchronous acknowledgment signal for the i_rst_n reset.

Do not deassert the i_rst_n reset until the o_rst_ack_n asserts.

o_tx_rst_ack_n Active-low asynchronous acknowledgment signal for the i_tx_rst_n reset.

Do not deassert the i_tx_rst_n reset until o_tx_rst_ack_n asserts.

o_rx_rst_ack_n Active-low asynchronous acknowledgment signal for the i_rx_rst_n reset. Do not deassert the i_rx_rst_n reset until o_rx_rst_ack_n asserts.
operating_speed Indicates the current PHY speed set using the speed switch methodologies. This signal does not reflect the transceiver data rate.
