What is a Software Product Line (SPL) Architecture?

A Software Product Line is NOT

Product Line Adoption and Institutionalization

Speaking from Experience

How Zephyr is being used as an SPL

Costs of a Software Product Line

SPL Core Asset Support: Architecture

SPL Core Asset Support: Software Components Must be designed to be general without a loss of performance must build in support for variation points

SPL Core Asset Support: Test Plans/Cases/Data Must consider variation points and multiple instances of the product line

SPL Core Asset Support: Tools and Processes Must be more robustan required for single product development

SPL Core Asset Support: Project Plans Must be generic or be made extensible to accommodate product variations

SPL Core Asset Support: People, Skills, and Training Must involve training and expertisecentered around the assets and procedures associated with the product line

Assessment: What is needed for SPL Best Practice? Starting with Zephyr v2.6.0 functionality • Embrace Extensibility . How is each aspect of the ecosystem impacted by module

Proposals: Embrace Extensibility (cont) MISRA Dir 3.1 (Required), states

Proposals: Embrace Life REUSE Live REUSE includes topologies where the Zephyr repository is just another module in the workspace • Proposal The Zephyr document generation tools support workspace-leve…

Proposals: Embrace Composability Composability means managing boards, drivers, and subsystems so that they can be assembled into a working device without requiring crafting or tuning

Multi-Project Integration Issues: Documentation

Multi-Project Integration Issues: Verification

Multi-Project Integration Issues: Implementation

Multi-Project Integration Issues: Design

Multi-Project Integration Issues: Requirements

Engineering, the Path Forward Software Product Line is the current best practice model for what we are trying to achieve with rouse of Copen source software in embedded systems.

Description:

Explore a comprehensive field report on implementing a Software Product Line (SPL) Architecture using Zephyr. Gain insights into SPL concepts, adoption strategies, and real-world experiences. Learn how Zephyr serves as an SPL, understand the associated costs, and delve into core asset support for architecture, software components, test plans, tools, processes, project plans, and personnel. Discover best practices for SPL implementation, starting with Zephyr v2.6.0 functionality. Examine proposals for embracing extensibility, life reuse, and composability in SPL development. Address multi-project integration challenges across documentation, verification, implementation, design, and requirements. Conclude with a forward-looking perspective on SPL as a best practice model for open-source software reuse in embedded systems.
