-- This entity takes VGA signals as input (in the form of 8-bit RGB words
-- and HSYNC/VSYNC signals) and produces TMDS signals as output.
--
-- The input side of this entity may be connected to SVGACTRL or APBVGA
-- components from GRLIB. The output side of this entity may be connected
-- to a TMDS transmitter for a HDMI or DVI output port.
--
-- The output operates in DVI mode: no guard bands and no data islands
-- are sent. This is actually not allowed on HDMI links, but HDMI devices
-- should just accept it in DVI-compatibility mode.

-- Description: Converter inteneded to connect a SVGACTRL core to a Chrontel
-- CH7301C DVI transmitter. Multiplexes data and generates clocks.
-- Tailored for use on the Xilinx ML50x boards with Leon3/GRLIB
-- template designs.
--
-- This multiplexer has been developed for use with the Chrontel CH7301C DVI
-- transmitter. Supported multiplexed formats are, as in the CH7301 datasheet:
--
-- IDF Description
-- 0 12-bit multiplexed RGB input (24-bit color), (scheme 1)
-- 1 12-bit multiplexed RGB2 input (24-bit color), (scheme 2)
-- 2 8-bit multiplexed RGB input (16-bit color, 565)
-- 3 8-bit multiplexed RGB input (15-bit color, 555)
--
-- This core assumes a 100 MHz input clock on the 'clk' input.
--
-- If the generic 'dynamic' is non-zero the core uses the value vgao.bitdepth
-- to decide if multiplexing should be done according to IDF 0 or IDF 2.
-- vago.bitdepth = "11" gives IDF 0, others give IDF2.
-- The 'idf' generic is not used when the 'dynamic' generic is non-zero.
-- Note that if dynamic selection is enabled you will need to reconfigure
-- the DVI transmitter when the VGA core changes bit depth.

-- Description: Syncronous 2-port fifo with tech selection
-----------------------------------------------------------------------------
-- Revisions:
-- 2014/12/16 Pascal Trotta: support for generic fifo
-- Notes: Generic fifo has the following features & limitations:
-- -almost full is driven only in write clock domain;
-- -almost empty is driven only in read clock domain;
-- -full and empty are driven in both clock domains;
-- -usedw is re-computed in each clock domain;
-- -in "first word fall through" mode empty should be observed as data
-- valid signal. If renable is asserted while empty='0', and at the
-- next read clock rising edge empty='1', then new read data is not
-- valid because fifo is empty. This does not apply in standard fifo
-- mode, i.e., when empty is asserted, the last read data is valid;
-- -supports only sepclk=1, i.e., asynchronous read/write clocks.
-- -it works also if rclk = wclk, but synchronization stages and gray
-- encoder/decoder are always instantiated, even if not necessary.

-- Description: GMII to SGMII interface
------------------------------------------------------------------------------
--------------------------------------------------------------------------------
-- Description: This is the top level vhdl example design for the
-- Ethernet 1000BASE-X PCS/PMA core.
--
-- This design example instantiates IOB flip-flops
-- and input/output buffers on the GMII.
--
-- A Transmitter Elastic Buffer is instantiated on the Tx
-- GMII path to perform clock compenstation between the
-- core and the external MAC driving the Tx GMII.
--
-- This design example can be synthesised.
