RISC-V debug solutions
RISC-V is a new open source instruction set architecture, initially developed by UC Berkeley but now being more widely adopted.
As a member of the RISC-V Foundation, UltraSoC is deeply involved in developing and defining the debug architecture for RISC-V standards. UltraSoC fully supports both standards-based and proprietary debug approaches. We were the first company to offer a RISC-V processor trace solution, supporting both open source and commercial processors including those from Andes, Codasip, Microchip, Roa Logic, SiFive and Syntacore.
RISC-V processor trace now standardised: Even open source needs agreed specs
RISC-V processor trace spec is ratified
After eighteen months of hard work, it’s done: the RISC-V processor trace spec is ratified. This is excellent news and everyone involved should congratulate themselves on a job well done. Read the news here on the RISC-V Foundation website. The RISC-V specifications, including Trace, are all available to view here.

Presentation: Processor Trace in a Holistic World
UltraSoC CTO Gajinder Panesar’s presentation at the 8th RISC-V Workshop in Barcelona outlined the importance of being able to debug in a holistic manner; to make the move to RISC-V as seamless as possible there needs to be an eco-system beyond the core itself.
“Esperanto’s goal is to make RISC-V the architecture of choice for the most demanding AI and machine learning applications,” said Dave Ditzel, Founder and CEO of Esperanto. “UltraSoC’s IP will help our users see complex interactions between processors so they can understand what is going on and how to optimize performance better. Developing and debugging software utilizing thousands of RISC-V cores will be easier with the advanced analytics that UltraSoC’s IP will provide.”
“The N25 and NX25 AndesCore processors are selected by our customers for their exceptional performance/power, flexible configurations, and comprehensive development tools. Choosing UltraSoC as our preferred partner for embedded analytics, trace and validation gives our customers an advanced development environment with insight into SoC operations and processor execution without disturbing target behaviour.
UltraSoC has shown itself to be committed to the development of the RISC-V ecosystem and hence it is clearly the best partner for our V5 RISC-V architecture. We are delighted to already be engaged with multiple mutual customers using Andes processor N25/NX25 with UltraSoC’s IP and trace solution to address their demanding applications.”

Developing and supporting RISC-V debug standards
UltraSoC fully supports all of the major standards – both established and emerging – for RISC-V debug. And because we can monitor all major CPUs and custom logic, and perform protocol-aware probing of common buses, you can be certain that we can support you, and free you to make the best design choices for your SoC design. You can read more about our RISC-V solutions by downloading our product brief. For more information on RISC-V in general, including a presentation on debug by our CTO Gadge Panesar, visit the proceedings page of the 5th RISC-V workshop, which took place at Google’s Quad Campus in Mountain View, California.
“UltraSoC continues to prove itself invaluable in helping Microsemi cement our leadership position in SoC development.
We’re committed to providing a complete solution for development teams looking to leverage the RISC-V architecture, in a broad range of applications. Working with UltraSoC reinforces and tangibly demonstrates that commitment to our customers.”
RISC-V Foundation Event Series
UltraSoC is pleased to support and participate in the RISC-V Foundation event series.
RISC-V Summit 2019
We participated in the 2nd RISC-V Summit in San Jose (Dec 10-12) and demonstrated the industry’s only commercial debug and trace solution for RISC-V – as well as showed exciting developments that bring the potential of the RISC-V architecture to chip designers. Also, following hot on the heels of our announcement that we have joined the OpenHW Group, we announced some exciting news about our RISC-V trace solutions.
UltraSoC CTO Gajinder Panesar and VP Engineering Iain Robertson presented in the main program on ‘Every CPU Cycle Counts’. Also CEO Rupert Baines presented on the Western Digital booth, and Gajinder participated in a Processor IP Showcase panel session.
UltraSoC participated in the RISC-V Day Workshop Zurich in June 2019 and demonstrated its embedded analytics technology.
UltraSoC participated in the RISC-V China Roadshow in May 2019 which provided the chance to find out how to get started with RISC-V, via engaging presentations from Foundation members including UltraSoC, Alibaba, Andes and NXP, amongst many others.
UltraSoC participated in the RISC-V Workshop Taiwan in early 2019 where delegates joined the expansive and international RISC-V ecosystem to discuss current and prospective RISC-V projects and implementations, as well as influence the future evolution of the instruction set architecture (ISA).
