ICD Template

This page provides the template to describe every a subsystems physical and virtual interfaces. This allows other subsystems to treat yours as a black box, focusing only on the input/outputs to ensure the system works in unison.

Like the rest of this Wiki, this page is a living document and will be updated whenever new information becomes available.

Introduction

This page outlines the mechanical, electrical, thermal, and data interfaces of the XXX Subsystem.

Part/Component Interfaces

For every component that interacts with another part external to the subsystem, a new section will be created to fully describe appropriate interactions and interfaces. Each sections should begin with a drawing of the part/component, and each type of interface will be described in further detail in the following subsections.
