POD Directories

<<intro

Directory structure

All filenames must be written in lower case, the only one authorized special caracter is "_" and can be used as separator.

POD Software directory

 pod/
 |-- bin/
 |   |-- core/

 |   |	 `-- vhdl/
 |   |-- commandline/
 |   `-- toolchain/

Directory description:

• bin : binary files for POD.
• busses : contains the bus descriptions.
• library: contains the available components.
• platforms: contains the platform descriptions.
• templates: code templates used by POD.
• toolchains: contains the toolchain descriptions.

"components" directory

Each component in the library has a dedicated directory with one or more xml file descriptions and subdirectories.

 wb_led/
 |-- drivers_templates/
 |   `-- linux/
 |       |-- Kconfig
 |       |-- Makefile
 |       |-- led.c
 |       `-- led.h
 |-- doc/
 |   |-- TODO
 |   |-- ChangeLog
 |   `-- README
 |-- hdl/
 |   `-- led.vhd
 |-- ledwb16.xml
 `-- ledwb8.xml

Subdirectories can be of type:

• drivers: driver files required for the compilation of the driver.
• doc: component documentation.
• hdl: contains the hdl files for the synthesis.

"platforms" directory

A platform directory contains one xml file and some subdirectories :

• simulation : this directory contains the simulation files for this architecture.
• doc : documentation for the given platform.

 apf9228/
 |-- apf9328.xml
 |-- doc/
 `-- simulation/

Project directory

The root directory name is the project name.

 project1/
 |-- binaries/
 |   |-- project1.bin
 |   `-- project1.bit
 |-- components/
 |   |-- button01/
 |   `-- led01/
 |-- objs/
 |-- project1.xml
 |-- drivers/
 |-- synthesis/
 `-- simulation/
     `--projecttest.vhd

A XML file describes the project and the directories :

• binaries: contains the bitstream of the FPGA.
• components: contains one directory for each instance in project.
• obj: contains the files generated by the third party tools (like ise files)
• simulation: testbench for the project.
• synthesis : contains the synthesis files.
• drivers : contains the drivers for each Virtual Peripheral in a project.
