-- Title : WRPC reference design for SVEC
-- Project : WR PTP Core
-- URL : http://www.ohwr.org/projects/wr-cores/wiki/Wrpc_core
-------------------------------------------------------------------------------
-- File : svec_wr_ref_top.vhd
-- Author(s) : Dimitrios Lampridis <dimitrios.lampridis@cern.ch>
-- Company : CERN (BE-CO-HT)
-- Created : 2017-02-16
-- Last update: 2017-02-17
-- Standard : VHDL'93
-------------------------------------------------------------------------------
-- Description: Top-level file for the WRPC reference design on the SVEC.
--
-- This is a reference top HDL that instanciates the WR PTP Core together with
-- its peripherals to be run on a SVEC card.
--
-- 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.
