3.8. Asserting Reset

A soft reset controller handles all non-PCIe reset scheduling for F-tile in PMA Direct and FEC Direct modes. The controller flow is an internal component of the larger F-tile IP flow, and is supported by a tile IP auto-instantiation and auto-connection flow.

Asserting a reset sequence ensures that the physical medium attachment (PMA) in each channel initializes and functions correctly. You can reset the transmitter (TX) and receiver (RX) data paths independently or together.
