1.10. Interface Signals

This section describes the interface signals at design example level. All design example has the same interface signals except the Avalon-MM interface for design example with IEEE 1588v2 with wrapper file.

The NUM_UNSHARED_CHANNELS are determined by the equation below:

NUM_UNSHARED_CHANNELS = (SHARED_REFCLK_EN == 1) ? 1: NUM_CHANNELS

NUM_CHANNELS and SHARED_REFCLK_EN are parameters set by user.
