# Main Goals

This package provides a unified abstract project model for HDL designs and EDA tools.
Third-party frameworks can derive own classes and implement additional logic to create
a concrete project model for their tools.

Frameworks consuming this model can build higher level features and services on top of
such a model, while supporting multiple input sources.

# Data Model

1. The toplevel element is a `Project`, which contains one or multiple designs.
2. A `Design` is a variant of a project and contains filesets.
3. A `FileSet` contains files or further sub-filesets.
4. A `File` represents a single file. E.g. source files, configuration files, constraint files.
5. A `VHDLLibrary` represents a group of `VHDLSourceFile`s being compiled into the same VHDL library.

# Features

* Construct a project model:  
  * top-down (project &rarr; design &rarr; fileset &rarr; file) or
  * bottom-up (file &rarr; fileset &rarr; design &rarr; project) or
  * parsing a project file.

* Designs, filesets and files can use absolute or relative paths.
  * `ResolvedPath` returns the resolved absolute path to an object.

* Projects, designs, filesets and files can be validated (e.g. if the path exists).

* Projects, designs, filesets and files can have user-defined attributes.
  * User-defined attributes are resolved bottom-up.

# Project File Readers

## OSVVM `*.pro` File Reader

ProjectModel can read `*.pro` files and extract source files. Included `*.pro` files
are represented as sub-filesets.

## Xilinx Vivado `*.xpr` Reader

ProjectModel can read `*.xpr` files and extract source, constraint and simulation
files while preserving the fileset structure.

# Use Cases

* Reading OSVVM's `*.pro` files.
* Reading Xilinx Vivado's `*.xpr` files.

# Examples

```python
from pathlib import Path
from pyEDAA.ProjectModel import Project, Design, FileSet, VHDLSourceFile

print(f"Current working directory: {Path.cwd()}")
projectDirectory = Path.cwd() / "../project"
print(f"Project directory: {projectDirectory!s} - {projectDirectory.exists()}")

project = Project("myProject", rootDirectory=projectDirectory)
designA = Design("designA", project=project, directory=Path("designA"))
designAFileset = FileSet("srcA", design=designA)
for vhdlFilePath in designAFileset.ResolvedPath.glob("*.vhdl"):
	designAFileset.AddFile(VHDLSourceFile(vhdlFilePath))

libFileset = FileSet("lib", Path("../lib"), design=designA)
for vhdlFilePath in libFileset.ResolvedPath.glob("*.vhdl"):
	libFileset.AddFile(VHDLSourceFile(vhdlFilePath))

print(f"All VHDL files in {designA.Name}:")
for file in designA.Files(fileType=VHDLSourceFile):
	print(f"  {file.Path}")
```
