SiFive is on a mission to make it easier and faster to build
custom chips for the new age of computing based on data, AI, and
communications. SiFive is the leading provider of commercial
processor cores using the exciting, new RISC-V standard being
adopted and evaluated by leading technology companies worldwide.
Founded by the inventors of RISC-V, and led by a team of seasoned
industry executives, SiFive offers the expertise, tools, and tech
to enable customized silicon to be developed specifically for each
You will be joining a team with passion and purpose:
democratizing access to silicon, to unlock customer roadmaps and
enable new product experiences in exciting new growth markets.
Location: Please note that due to COVID-19, all US-based
internships in 2021 are remote and therefore open to all US-based
candidates. In the chance that work-from-home restrictions are
lifted, and you do not live near one of our offices, SiFive may
arrange you to travel to the local office or HQ to meet the
What You Will Work On:
As an Intern on the Verification team, you will get a chance to
work on one of the following 4 projects:
- Current Run Status Progress Page
You will get an chance to investigate and collect data from
currently running flows (Chisel, FIRRTL, Sitest) into a database
that is capable of handling hundreds of thousands of entries a day.
Once the data is collected it should be presented via a web-based
interface that can be used to track live status of what is running,
what has finished and what is left to run. This will provide
valuable feedback to various team members to more accurately
predict when things will finish and if there are issues with
- Automated Simulation Performance Collection
In this project, you will be making decisions on whether a new
tool is meeting the performance improvements claimed by developers.
To hold them accountable we must have data collected regularly that
is run in a controlled environment to compare with runs on new tool
versions. Further, this collected data can be used to guide
timeouts of various processes to ensure we are not allowing changes
that further increase turnaround time. This collection of data
could be used for compute forecasting and, if data is easily
accessible for users, to compare runtime to some known good
- Project Health Dashboard
Here you would be working on creating a central location or a
dashboard to help keep an eye on the progress of SiFive's projects.
Each project we are working on should have a central location that
is automatically updated daily to provide a picture of the health
of that project. Key information to gather is coverage numbers,
pass rates, bug rates, and regressions run. Most likely this would
have to be done in a web-based application.
- Evaluating FORCE-RISC-V Instruction Stream generator
This is an open-source Test Generator being released by
FutureWei. The developer claims that it has great MP capability and
is proven with commercial products. It is C++ based and has Python
as a front-end template developing language. In this project, you
would be evaluating its strengths and see if it can bring us any
extra benefits. As most generators have different advantages, this
would be a great project to work on.
What You Will Learn:
- Understanding of what is needed in the verification industry
for writing quality code.
- Collecting data from numerous sources.
- Handling of large amounts of data.
- Creating scalable web services.
- Random Test Generator
- How to develop templates (Project 4)
- Pursuing a Bachelor's, Master's or PhD in Computer Engineering,
Computer Science, Electrical Engineering, or a similar
- Familiarity or academic experience with data structures.
- Web Programming Experience (Project 3 only)
- Python/C++ experience and Basic Architecture Background
(Project 4 only)
