Board: Zynq 7z30
FPGA: Kintex-7
# Current step:
Connecting Ashwin's core (slow interface to the system is almost done, have to completely rewrite phy-level). Feels like making the phy works is going to require a lot of effort
Testing basic functionallity of a host.
Trying out pio access.
Fullfilling device-side drivers and monitors via tasks.
Tests are mostly manual, relied on a common sense and waveforms instpection. Still, complatible both with gtx-gpl and unisims/gtx
# Going to do afterwards:
Complete and test the 'current step'. Write host controller with ~same functionallity, check if it works with previously verified higher-level code.
And then to spin out the full-compatible functionallity (ideally somewhere to the level of ahci)
Test dma functionallity of the host.
Make cocotb testbench - gtx-gpl only - random payload high-level verification testing purposes.
Create a base of regression tests, containing lower-level tests - both gtx-gpl and unisims/gtx.
Improve an implementation of DMA control module.
Finally decide what to do with a driver and modify application level (actally, write it from scrap) correspodning to driver's interfaces.

-- ENTITY: crc
-- Version: 1.0
-- Author: Ashwin Mendon
-- Description: This sub-module implements the CRC Circuit for the SATA Protocol
-- The code takes 32-bit data word inputs and calculates the CRC for the stream
-- The generator polynomial used is
-- 32 26 23 22 16 12 11 10 8 7 5 4 2
-- G(x) = x + x + x + x + x + x + x + x + x + x + x + x + x + x + 1
-- The CRC value is initialized to 0x52325032 as defined in the Serial ATA
-- specification

-- ENTITY: sata_core
-- Version: 1.0
-- Author: Ashwin Mendon
-- Description: The SATA core implements the Command, Transport and Link Layers of
-- the SATA protocol and provides a Physical Layer Wrapper for the GTX
-- transceivers. The Physical Layer Wrapper also includes an Out of Band
-- Signaling (OOB) controller state machine which deals with initialization
-- and synchronization of the SATA link. It can interface with SATA 2
-- Winchester style Hard Disks as well as Flash-based Solid State Drives
-- The core provides a simple interface to issue READ/WRITE sector commands.
-- The DATA interface is 32-bit FIFO like.
-- A 150 MHz input reference clock is needed for the GTX transceivers.
-- The output data is delivered 4 bytes @ 75 MHz (user output clock)
-- for a theoretical peak bandwidth of 300 MB/s (SATA 2).
--
--
-- PORTS:
-- Command, Control and Status --
-- ready_for_cmd : When asserted, SATA core is ready to execute new command.
-- This signal goes low after new_cmd is asserted.
-- It also serves as the command done signal
-- new_cmd : Asserted for one clock cycle to start a request
-- cmd_type : "01" for READ request and "10" for WRITE request
-- sector_count : Number of sectors requested by user
-- sector_addr : Starting address of request
-- Data and User Clock --
-- sata_din : Data from user to Write to Disk
-- sata_din_we : Write Enable to SATA Core when FULL is low
-- sata_core_full : SATA Core Full- de-assert WE
-- sata_dout : Data output from SATA Core
-- sata_dout_re : Read Enable from SATA asserted when EMPTY is low
-- sata_core_empty : SATA Core Empty- de-assert RE
-- SATA_USER_DATA_CLK_IN : SATA Core Write Clock
-- SATA_USER_DATA_CLK_OUT : SATA Core Read Clock
-- sata_timer : SATA core timer output to check performance
--PHY Signals--
-- CLKIN_150 : 150 Mhz input reference clock for the GTX transceivers
-- reset : Resets GTX and SATA core; can be tied to a software reset
-- LINKUP : Indicates Link Initialization done (OOB) and SATA link is up
--GTX transmit/receive pins: Connected to the FMC_HPC pins on a ML605 board
-- TXP0_OUT, TXN0_OUT, RXP0_IN, RXN0_IN

-- ENTITY: sata_link_layer
-- Version: 1.0
-- Author: Ashwin Mendon
-- Description: This sub-module implements the Transport and Link Layers of the SATA Protocol
-- It is the heart of the SATA Core where the major functions of sending/receiving
-- sequences of Frame Information Structures (FIS), packing them into
-- Frames and sending/receiving Frames are accomplished.
-- The Master FSM deals with the Transport Layer functions of sending receiving FISs
-- using the TX and RX FSMs.
-- The TX and RX FSMs use the crc, scrambler and primitive muxes to construct and
-- deconstruct Frames. They also implement a Frame transmission/reception protocol.

-- ENTITY: scrambler
-- Version: 1.0
-- Author: Ashwin Mendon
-- Description: This sub-module implements the Scrambler Circuit for the SATA Protocol
-- The code provides a parallel implementation of the following
-- generator polynomial
-- 16 15 13 4
-- G(x) = x + x + x + x + 1
-- The output of this scrambler is then XORed with the input data DWORD
-- The scrambler is initialized to a value of 0xF0F6.
-- The first DWORD output of the implementation is equal to 0xC2D2768D
-- PORTS:
