What is MyHDL-numeric?

----------------------

MyHDL-numeric is an enhancement of the [MyHDL](http://www.myhdl.org)

package which provides support for **multiple VHDL entities**

([MEP110](http://dev.myhdl.org/meps/mep-110.html))

and **fixed-point numbers** ([MEP111](http://dev.myhdl.org/meps/mep-111.html)).

The **fixed-point numbers** are based on the bit-array class, that

provides support for three new types: ``sintba`` (signed integer), ``uintba``

(unsigned integer) and ``sfixba`` (signed fixed point).

Presently it only supports these new types on VHDL, and makes use of the

IEEE fixed_pkg available on VHDL-2008. If this version is not available,

it can also make use of the proposed implementation available for VHDL-93.

You can find the sources under the ``vhdl`` directory. The implementation

also takes into account the correction presented in

[DOI: 10.13140/RG.2.2.33860.42884](https://dx.doi.org/10.13140/RG.2.2.33860.42884).

An example of the numeric enhancement can be found under the directory

``example/cordic``.

License

-------

MyHDL is available under the LGPL license.  See ``LICENSE.txt``.

Installation

------------

If you have superuser power, you can install MyHDL-numeric as follows:

```

python setup.py install

```

This will install the package in the appropriate site-wide Python

package location.

Otherwise, you can install it in a personal directory, e.g. as

follows:

```

python setup.py install --home=$HOME

```

In this case, be sure to add the appropriate install dir to the

``$PYTHONPATH``.

If necessary, consult the distutils documentation in the standard

Python library if necessary for more details;

or contact me.

You can test the proper installation as follows:

```

cd myhdl/test/core

py.test

```

To install co-simulation support:

Go to the directory ``cosimulation/`` for your target platform

and following the instructions in the ``README.txt`` file.
