Free and Open Source Silicon (FOSSi): Adaptation for Open Semitech

Core Beliefs and Objectives for Open Semitech

Introduction

Open Semitech aims to revolutionize the semiconductor industry by embracing the principles of Free and Open Source Silicon (FOSSi). Our initiative is rooted in the belief that digital building blocks, such as IP cores and system-on-chips, should be open and freely accessible. This approach fosters innovation, collaboration, and democratizes access to cutting-edge technology.

Objectives

1. Accessibility: Ensure that hardware design is accessible to everyone by providing free and open-source components and tools.

2. Innovation: Encourage innovation through community-driven development and shared knowledge.

3. Reliability and Trust: Ensure components are reliable and interoperable through clear interface definitions and rigorous testing.

Target Audience

Hobbyists:

• Utilize affordable, reprogrammable hardware like FPGAs to experiment and innovate.

• Share their designs and improvements with the broader community.

Academics:

• Use FOSSi components for cutting-edge research and educational purposes.

• Integrate open-source components into curricula to teach digital hardware design.

Companies:

• Incorporate open-source IP blocks into products to reduce development costs and accelerate time-to-market.

• Open-source their designs to build a community around their products, gaining publicity and external contributions.

Components and Systems in Open Semitech

Hardware Description:

• Languages: Designs are typically described using hardware description languages (HDLs) like VHDL, Verilog, or SystemVerilog.

• Schematic: In some cases, designs can be represented as schematics.

Design Process:

• Synthesis: Convert the HDL or schematic into a netlist, a structural representation of the hardware design.

• Implementation: Map the netlist onto the physical hardware layout. For ASICs, this results in silicon masks; for FPGAs, it produces a bitstream to program the device.

Interoperability and Testing:

• Interface Definitions: Essential for ensuring different components can work together seamlessly.

• Testbenches: Provide a controlled environment to simulate and verify the functionality of designs.

• Test Strategies: Necessary to catch and fix hardware bugs, especially critical in ASIC production where errors are costly to fix.

Historical Context

Open Source Movements:

• Homebrew Computer Club: A seminal group from the 1970s that freely exchanged hardware and software designs, laying the foundation for both movements.

• Linux and Collaborative Platforms: Demonstrated the viability and benefits of open-source software, influencing the hardware community.

Open Source Hardware (OSHW):

• Platforms like Arduino and Raspberry Pi have democratized hardware design, making it accessible to a wider audience.

• OSHW has seen rapid growth due to its affordability and ease of use.

FOSSi Ecosystem

Electronic Design Automation (EDA) Tools:

• Traditional Tools: Historically expensive and complex, limiting accessibility.

• Open Source EDA: Development of open-source EDA tools is encouraged to support system synthesis and testing, lowering barriers for designers.

• FPGA Tools: Vendors provide free tools for small FPGAs, making entry-level development affordable.

Community and Collaboration:

• Platforms: Online platforms facilitate collaboration and sharing of FOSSi designs and tools.

• Events: Workshops, conferences, and hackathons promote knowledge sharing and community building.

Implementation Strategy

1. Collaborative Development:

   • Foster partnerships among hobbyists, academics, and companies to develop and share open-source silicon components.

   • Use platforms like GitHub to manage projects, track issues, and collaborate on code.

2. Accessible Design Tools:

   • Promote the use and development of open-source EDA tools like OpenROAD and Yosys.

   • Provide tutorials and resources to help new users get started with these tools.

3. Community Involvement:

   • Build a robust community around open-source IP blocks and digital systems.

   • Organize and participate in events like hackathons, workshops, and conferences to foster community engagement and collaboration.

4. Clear Protocols and Testing:

   • Ensure interoperability through well-defined protocols and interface standards.

   • Maintain rigorous testing standards to produce reliable hardware designs.

   • Develop and share testbenches and test strategies to facilitate comprehensive testing of FOSSi components.

5. Education and Outreach:

   • Create educational content and resources to help new users learn about FOSSi and how to use it effectively.

   • Partner with universities and educational institutions to integrate FOSSi components into their curricula.

6. Industry Engagement:

   • Encourage companies to adopt FOSSi components in their products.

   • Highlight success stories and case studies of companies benefiting from open-source silicon to promote adoption.

Conclusion

By implementing these strategies, Open Semitech can effectively embrace FOSSi principles, driving innovation and collaboration in the semiconductor industry. This will create a vibrant and engaged community around open-source silicon development, ultimately democratizing access to advanced digital technology.
