What is the time taken by the GTS Ethernet Hard IP for Tx and Rx reset release to mission mode?

Description

On hardware, the GTS Ethernet Hard IP transitions to mission mode after reset release within the following times, measured from reset de-assertion to the corresponding ready indicators:

• Transmit (Tx): approximately 4.55 ms, until tx_lane_stable is asserted
• Receive (Rx): approximately 11.2 ms, until rx_pcs_ready is asserted

Resolution

The observed delay is expected behavior for the GTS Ethernet Hard IP; no workaround is required. The design should use these ready indicators to determine mission-mode readiness rather than relying on a fixed delay. Simulation times are shorter because of simplified fast simulation models.

Additional Information

Hardware time differs from simulation due to fast sim models. In simulation, the GTS Ethernet Hard IP enters mission mode after reset release within these times,

• Transmit (Tx): approximately 1 ms, until tx_lane_stable is asserted
• Receive (Rx): approximately 1.016 ms, until rx_pcs_ready is asserted
