Open FPGA Stack (OFS)
Driving scalability and standardization within the open source FPGA community.
Open FPGA Stack (OFS)
Access the Open Source Repositories on GitHub
Open FPGA Stack (OFS) is the first complete hardware and software infrastructure that is fully open sourced and comprises composable hardware code and upstreamed kernel code to kernel.org to enable a collaborative community of FPGA developers.
All source code and technical documentation is open source in the OFS GitHub and enables development using the Intel® Stratix® 10 FPGA and Intel Agilex® FPGA.
Customize Unique FPGA-based Boards and Platforms
Open FPGA Stack is a scalable, open source hardware and software infrastructure delivered via git repositories that provides an efficient approach to customize your own unique acceleration platform solutions using an Intel, 3rd party, or custom board. OFS is being used by Intel and selected third-party platforms featuring our Intel® Stratix® 10 FPGA, Intel Agilex® FPGA, and future Intel® FPGA device families.
Hardware developers can try out OFS on the reference platforms before porting to their own boards. Application developers can use our 3rd Party Board Catalog of OFS-enabled boards to select an option and get started.

How Does Open FPGA Stack (OFS) Make My Project Easier?
Board Developers
Use the open source, modular infrastructure to quickly create application-specific FPGA Interface Managers (FIMs) tailored to the differentiated needs of their boards and target workloads.
Software Developers
Leverage upstreamed Linux kernel drivers along with our open-source Open Programmable Acceleration Engine (OPAE) software development kit to accelerate integration into common application frameworks, enabling cross-platform portability and hardware management at runtime.
Application Developers
Tap into a proven infrastructure and expanding ecosystem to achieve greater portability and return on investment for their workloads across a growing number of OFS-enabled platforms and workloads.
Leverage oneAPI with OFS
OFS includes support for development with high-level design languages (HLD) like oneAPI so you can easily customize your board support package to build applications on Intel, custom, or 3rd party platforms. HLD design languages like oneAPI allow you to use familiar programming languages like Data Parallel C++ integrated into familiar development environments.

FAQs
Frequently Asked Questions
The vision for Open FPGA Stack has always been to develop an engaged, participating, and growing community of FPGA developers (not specific to Intel) on GitHub by open sourcing our source code. With that vision in mind, we have generalized our branding to “Open FPGA Stack” as of May 2023.
At this time, Open FPGA Stack is an Intel driven technology and Intel will continue to be the main contributor of Open FPGA Stack until we support full code contributions. Intel will continue to update and maintain the repository and provide technical assistance to customers for the time being.
No. The Open FPGA Stack infrastructure is tested and validated using three reference platforms: Intel® FPGA PAC D5005 (Intel® Stratix® 10 FPGA), Intel® FPGA SmartNIC N6000-PL Platform (Intel Agilex® FPGA) and Intel® FPGA IPU F2000X-PL. However, OFS is intended to enable custom platform, software, and workload development, so we fully expect users to port to other device variants and platforms, including devices with FPGAs from other vendors. Customers are welcome to use 3rd party, custom, or Intel branded platforms.
OFS kernel drivers are being upstreamed to the Linux kernel (kernel.org), which enables software developers to port to their operating system (OS) distribution(s) of choice and for OS vendors to natively support these drivers in their own distributions. This means that developers have flexibility and freedom of choice for their target Linux distribution(s) to support their platforms and applications. More benefits of upstreaming include community code reviews, contributions to lifetime maintenance, and reusability with API changes.
Not yet but we are currently defining the methodology we want to employ for code contributions.
