5.3.3. Reset Scheme

The global reset signal of the design example is asynchronous and active-high. Asserting this signal resets all channels and their components. Upon power-up, reset the design example (i_rst_n, i_tx_rst_n, and i_rx_rst_n).

An In-System Sources and Probes (ISSP) is instantiated to control the resets for the design.
