Axign - Audio chips for consumer electronics
The challenge
Axign B.V., leading innovator in audio chip technology, is on a mission to create the next generation of audio chips for consumer electronics. Learn more about Axign’s revolutionary Class D audio amplifier technology and their dedication to innovation at Axign’s website. To deal with their project’s growing complexity, they asked QBayLogic to help out with RTL engineering and streamlining their development process.
The solution
In collaboration with Axign, a multi-faceted approach was adopted:
- Continuous Integration pipelines were integrated along with software-based testing, transforming their testing procedures into a streamlined, accelerated verification process. This not only optimized their workflow, but ensured accurate and rapid results.
- At the heart of integrated circuits lies communication, often governed by common communication protocols. Simulator abstractions were implemented to more easily control these components in simulation without being bothered with protocol specific aspects.
The deliverables
Configurable Cocotb drivers for JTAG, AHB, (Q)SPI, and I2S were developed and assisted in designing and writing them. Additionally, an up-to-date, dependable way of working using GitLab and GitLab CI was established.
Moreover, Python and Cocotb support was offered, including upstreaming patches related to the interaction between cocotb, VPI, and Xcelium.
Our clients
Why QBayLogic?
At QBayLogic, we embrace the integration of software and digital engineering, recognizing their similarities rather than their differences. Axign’s pursuit of a combined software-hardware testing methodology aligned perfectly with our expertise, making us the ideal partner for this project. Not only did we facilitate Axign’s transition to a more efficient and sustainable workflow, but we also contributed to the development of next-generation audio chips. This project exemplifies our commitment to driving innovation by combining the strengths of software engineering and digital circuit design.
Applications where the applied expertise would also fit:
- Innovation partner: Paving the way for integrated innovations.
- Fast and reliable verification: Prevent problems rather than solving them.
- Protocol toolbox: digital IC communication on a high level.
- Future-proofing: Keeping up with growing complex digital designs
- Effective collaboration: A reliable workflow maintains engineering quality.
