Overview

A platform includes both the hardware and software associated with an SoC. It is organized under a directory that shares the same name as the SoC the user intends to design.

Figure 1: Detailed Structure of the Platform Directory.

In Figure 1, lec_apb is both the name of the SoC and the name of the corresponding directory.

File Structure

The structure under #(platform dir) is as follows:

Path	Usage	Description
./#(platform name).xml	Editable	SoC description file
./app/	Editable	Application development environment
./user/	Editable	User-managed environment
./util/	Editable	Utility environment
./sim_rtl/	Use Only	RTL simulation environment
./imp_XXXX/	Use Only	FPGA prototyping environment
./arch/	System Reserved	Generated from ./#(platform name).xml
./fpga_component/	System Reserved	Used in imp_XXXX

Functionality

- Creating a New Platform

Command:

cmd) cd #(platform base)
cmd) make new PLATFORM_NAME=#(platform name)

Result:
#(platform base)/#(platform name) is created,
which we refer to as #(platform dir).

- Designing a Platform

Prerequisite: Creating a New Platform

Command:

cmd) cd #(platform dir)
inst) Edit the ./#(platform name).xml file with a text editor.

- Synthesizing a Platform

Prerequisite: Designing a Platform
Command:
```
cmd) cd #(platform dir)
cmd) make syn
```
Result: #(platform dir)/arch is created.
Note: #(platform dir)/arch is automatically managed by the RVX tool.

- Cleaning All Platform Results

The following files and/or directories are maintained:
./#(platform name).xml, ./app, ./user, and ./util

cmd) cd #(platform dir)
cmd) make clean
