+-- Description: Top-level file for the WRPC reference design on the PXIe-FMC
+-- board.
+--
+-- This is a reference top HDL that instanciates the WR PTP Core together with
+-- its peripherals to be run on a PXIe-FMC board.
+--
+-- There are two main usecases for this HDL file:
+-- * let new users easily synthesize a WR PTP Core bitstream that can be run on
+--   reference hardware
+-- * provide a reference top HDL file showing how the WRPC can be instantiated
+--   in HDL projects.
