Training

In this two-hour tutorial session in Silicon Institute of Technology's NES 2020 Conference, Steve Hoover introduces TL-Verilog and Makerchip.

With our training partner, VLSI System Design, we occasionally offer interactive online training, including the 5-day Microprocessor for You in Thirty Hours (MYTH) Workshop, where, with no circuit design experience, you can create your own RISC-V core.

The video to the left promotes a 2-hour version of the training offered in VSDOpen 2020, which you can now access for free!

This online course, "Pipelining RISC-V with Transaction-Level Verilog," led by Steve Hoover and Kunal Ghosh includes numerous hands-on exercises to learn TL-Verilog.

Excellent presentation, examples and impressive tools. Perfect combination to offer so many concepts in just 3hs.

This 1-hr video, presented by Steve Hoover introduces TL-Verilog for verification engineers, highlighting the benefits of timing abstraction and transaction-level design for simplifying test harness construction and for making verification collateral more resilient to design changes.

Papers and Presentations

Transcending RTL

Steve Hoover, Jan Kuper, Jose Renau Invited Session, 57th Design Automation Conference, July 2020.

For this session, Steve Hoover called upon fellow innovators, Jan Kuper and Jose Renau, to showcase to the industry the breadth of opportunity that exists between RTL and high-level synthesis. The session covered the methodologies behind TL-Verilog, Clash, and Pyrope, three modern HDLs that are not simply better RTL languages, they are languages that are better than RTL.

Unleashing the Potential of Open-Source Silicon

Steve Hoover, Invited talk, VSDOpen, October 2019. (slides)

Steve Hoover describes the eminent transformation of the silicon industry resulting from cloud FPGAs, which will unlock a vibrant open-source silicon ecosystem, and introduces the 1st CLaaS open-source framework for developing FPGA microservices to accelerate web and cloud application, recognized by Google as a game-changer.

Open Source Silicon Trends and Opportunities

Steve Hoover, Invited talk, VSDOpen, October 2018. (slides)

There is great enthusiasm for open-source silicon, but there are obstacles... though not for long!

Top- Down Transaction-Level Design with TL-Verilog

Steve Hoover and Ahmed Salman, VSDOpen, October 2018. (paper)

This paper provides an early look at advanced modeling capabilities for flexible IP reuse. "Top-down design has long been explored, but it is, today, generally understood to be infeasible. We show that it is not."

Formally Verifying WARP-V, an Open-Source TL-Verilog RISC-V Core Generator

Steve Hoover and Ákos Hadnagy, ORConf and VSDOpen, September and October 2018. (paper, slides)

This work demonstrates the extreme benefits of timing abstraction and transaction-level design for verification modeling.

Timing-Abstract Circuit Design in Transaction-Level Verilog,

Steve Hoover, ICCD, November 2017. (paper & slides)

Timing-abstract design is a fundamental modeling premise of TL-Verilog. In the anonymous words of the reviewers:

"As a designer, I like TL-Verilog."

"This is a productive solution to a common problem."

"I especially liked the support for conditionals built into TL-Verilog and their application to clock gating."
