Machine Learning for Hardware Design Verification with Arm Ltd.

Project Description

This research project is a collaboration between Arm Ltd. and the Trustworthy Systems Laboratory at the University of Bristol. We will investigate how existing and novel machine learning techniques can be used to improve the results of simulation-based hardware design verification. Areas of improvement may include design coverage (code, functional, or other types), bug discovery probability, the number of simulations required to reach verification goals, the novelty of the internal states the design experiences during simulation, the novelty of the simulation’s outputs, or other areas we may choose during the project. We will prefer techniques that require no human intervention (e.g. to supply insight into the hardware), which are as easy as possible to train, and which can continue to learn from large numbers of data points. To enable this, Arm will provide access to problems and datasets of both academic and industrial interest, as well as collaboration with industrial researchers.

We are offering an opportunity to advance the state of machine learning in an area that is both highly valuable to industry, and not already saturated with competing ML researchers. Hardware verification is the most expensive and time-consuming part of commercial microprocessor development, so improvement in this area is of great commercial interest. Furthermore, the hardware verification process naturally creates large amounts of labelled data in a reproducible way, enabling research on novel datasets without requiring manual data gathering and annotation. However, the data in the hardware verification domain is a challenge to many traditional ML methods because hardware designs often do not have a continuous mapping between input stimuli and output behaviour. We are interested both in practical results (e.g. improvements in rates of bug discovery or the ability to target specific parts of the design during simulation) and in theoretical results (e.g. the creation of new ML algorithms that are especially suited to this kind of data).

Funding Information

The scholarship covers full UK/EU (EU applicants who have been resident in the UK for 3 years prior to 1 September 2019) PhD tuition fees and a tax-free stipend at the current RCUK rate (£15,009 in 2019/20). EU nationals resident in the EU may also apply, but will only qualify for PhD tuition fees.

Eligibility Requirements

A first-class degree in Computer Science, Computer Systems Engineering, Informatics, Microelectronic Design or a similar discipline is required. Excellent programming skills are essential. A good understanding of computer architecture and machine learning techniques will be required for the project. It would be an advantage to have a background in at least one of the following areas: machine learning, processor architecture and design, simulation-based testing, model-based design or testing techniques. Furthermore, you are able to quickly pick up new programming languages and you are willing to learn how to use state-of-the-art professional EDA tools for design verification. You are a competent presenter, writer and communicator, willing and able to work with our industrial collaborator.
