5.5.1.1.1. HSSI Serial Clock Source

The HSSI Serial Clock interface includes a source in the Start direction.

You can instantiate the HSSI Serial Clock Source interface in the _hw.tcl file as:

add_interface <name> hssi_serial_clock start

You can connect the HSSI Serial Clock Source to multiple HSSI Serial Clock Sinks because the HSSI Serial Clock Source supports multiple fan-outs. This Interface has a single clk port role limited to a 1 bit width, and a clockRate parameter, which is the frequency of the clock driven by the HSSI Serial Clock Source interface.

An unconnected and unexported HSSI Serial Source is valid and does not generate error messages.
