-# Xilinx ISE Makefile
-
-Tired of clicking around in Xilinx ISE? Run your builds from the command line!
-
-## Forked from..
-
-The original project is located at [Xilinx-ISE-Makefile](https://github.com/duskwuff/Xilinx-ISE-Makefile) and was created by [duskwuff](github.com/duskwuff/).
-
-Many thanks for the good work!
-
-## Requirements
-
-- Xilinx ISE, ideally 14.7 (the final version)
-
-  Works great on Linux. Windows Subsystem for Linux is tested and works well.
-
-- GNU (or compatible?) Make
-
-  Install this through Cygwin on Windows.
-
-## Creating a project
-
-To start building a project, you will need to create a file `project.cfg` in
-the top level of your project. This file is a text file sourced by Make, so
-it consists of `KEY = value` pairs. It must define at least the following keys:
-
-- `PROJECT`
-
-  The name of the project, used as a name for certain intermediate files, and
-  as the default name for the top-level module and constraints file.
-
-- `TARGET_PART`
-
-  The full part-speed-package identifier for the Xilinx part to be targeted,
-  e.g. `xc6slx9-2-tqg144`.
-
-- `XILINX`
-
-  The path to the appropriate binaries directory of the target Xilinx ISE
-  install, e.g.
-  `/cygdrive/c/Xilinx/14.7/ISE_DS/ISE`
-  or
-  `/opt/Xilinx/14.7/ISE_DS/ISE`
-  for typical installs.
-
-- `VSOURCE` and/or `VHDSOURCE`
-
-  The space-separated names of all Verilog and/or VHDL source files to be
-  used in the project.
-
-  You can define these on multiple lines using `+=`, e.g.
-
-      VSOURCE += foo.v
-      VSOURCE += bar.v
-
-  You can also add a library name to the source file, e.g.
-
-      VSOURCE += my_lib:foo.v
-      VSOURCE += my_lib:bar.v
-
-  The default library name is `work`.
-
-A simple `project.cfg` may thus resemble:
-
-    PROJECT = example
-    TARGET_PART = xc6slx9-2-cpg196
-
-    XILINX = /cygdrive/c/Xilinx/14.7/ISE_DS/ISE/bin/nt64
-
-    VSOURCE = example.v
-
-A number of other keys can be set in the project configuration, including:
-
-- `XILINX_PLATFORM`
-
-  The Xilinx name for the platform to build for, e.g. `nt64` or `lin`.
-  `nt64` is used by default for Windows systems, and `lin64` for Linux
-  systems, so you only need to set this if you explicitly need to use the
-  32-bit version of the tools for some reason.
-
-- `TOPLEVEL`
-
-  The name of the top-level module to be used in the project.
-  (Defaults to `$PROJECT`.)
-
-- `CONSTRAINTS`
-
-  The name of the constraints file (`.ucf`) to be used for the project.
-  (Defaults to `$PROJECT.ucf`.)
-
-- `COMMON_OPTS`
-
-  Extra command-line options to be passed to all ISE executables. Defaults to
-  `-intstyle xflow`.
-
-- `XST_OPTS`, `NGDBUILD_OPTS`, `MAP_OPTS`, `PAR_OPTS`, `BITGEN_OPTS`,
-  `TRACE_OPTS`, `FUSE_OPTS`
-
-  Extra command-line options to be passed to the corresponding ISE tools.
-
-  Defaults is:
-
-  ```
-  XST_OPTS        ?=
-  NGDBUILD_OPTS   ?=
-  MAP_OPTS        ?= -detail
-  PAR_OPTS        ?=
-  BITGEN_OPTS     ?=
-  TRACE_OPTS      ?= -v 3 -n 3
-  FUSE_OPTS       ?= -incremental
-  ```
-
-  Note that `XST_OPTS` will not appear on the command line during
-  compilation, as the XST options are embedded in a script file.
-
-  `MAP_OPTS` and `PAR_OPTS` can be set to `-mt 2` to use multithreading,
-  which may speed up compilation of large designs.
-
-  `BITGEN_OPTS` can be set to `-g Compress` to apply bitstream compression.
-
-- `PROGRAMMER`
-
-  The name of the programmer to be used for `make prog`. Currently supported
-  values are:
-
-  - `impact`
-
-    Uses Xilinx iMPACT for programming, using a batch file named
-    `impact.cmd` by default. The iMPACT command line may be overridden by
-    setting `IMPACT_OPTS`.
-
-    A typical batch file may resemble:
-
-        setMode -bscan
-        setCable -p auto
-        addDevice -p 1 -file build/projectname.bit
-        program -p 1
-        quit
-
-  - `digilent`
-
-    Uses the Digilent JTAG utility for programming, which must be installed
-    separately. The name of the board must be set as `DJTG_DEVICE`; the
-    path to the djtgcfg executable can be set as `DJTG_EXE`, and the index
-    of the device can be set as `DJTG_INDEX`. You can set the flash index
-    with `DJTG_FLASH_INDEX`.
-
-  - `xc3sprog`
-
-    Uses the xc3sprog utility for programming, which must also be installed
-    separately. The cable name must be set as `XC3SPROG_CABLE`; additional
-    options can be set as `XC3SPROG_OPTS`.
-
-- `PROGRAMMER_PRE`
-
-  A command to be run before programming. This can be used to use `sudo` or
-  `yes` to confirm programming.
-
-## Targets
-
-The Xilinx ISE Makefile implements the following targets:
-
-- `make default` (or just `make`)
-
-  Builds the bitstream.
-
-- `make clean`
-
-  Removes the build directory.
-
-- `make prog`
-
-  Writes the bitstream to a target device. Requires some additional
-  configuration; see below for details.
-
-- `make flash`
-
-  Writes the bitstream to a flash device.
-  **This is currently only for digilent implemented.**
-
-## Console output
-
-After a successful build, you will find the paths to the generated **reports** on the console. E.g.:
-
-```
-============ Reports.. ===========
-
-==== Synthesis Summary Report ====
- ./build/Example.srp
-
-======= Map Summary Report =======
- ./build/Example.map.mrp
-
-======= PAR Summary Report =======
- ./build/Example.par
-
-===== Pinout Summary Report ======
- ./build/Example_pad.txt
-
-```
-
-## Unimplemented features
-
-The following features are not currently implemented. (Pull requests are
-encouraged!)
-
-- Generation of SPI or other unusual programming files
-
-- CPLD synthesis
-
-- Synthesis tools other than XST
-
-- Display and/or handling of warnings and errors from `build/_xmsgs`
-
-- Running unit tests
-
-- Anything else (open an issue?)
