OpenROAD (https://theopenroadproject.org) is an open-source RTL-to-GDS tool that generates manufacturable layout from a given hardware description – in 24 hours, at advanced foundry nodes. OpenROAD lowers the cost, expertise and schedule barriers to hardware design, thus providing a platform for research, education and system innovation. This talk will present current status of the OpenROAD project and the roadmap for OpenROAD as it seeks to enable VLSI/EDA education, early design space exploration for system designers, research on machine learning in EDA, and more.

The talk will be focused on two majors points : why Open Hardware is as important as Open Source Software and the major challenges in building FOSS EDA tools.

Myrtle will introduce some of the recent developments in nextpnr; including easier ways of prototyping new architectures as well as some core algorithm improvements. They will also introduce FABulous, a highly flexible open source eFPGA fabric generator, and its close integration with nextpnr.

GHDL is an open-source VHDL simulator and synthesis tool. This talk will present the latest added features and some ideas for future development (in particular mixed simulation)

Open Source VHDL Verification Methodology (OSVVM) provides VHDL with buzz word verification capabilities including Transaction Level Modeling, Constrained Random, Functional Coverage, Scoreboards, FIFOs, Memory Models, Error and Message handling, and Test Reporting that are simple to use and feel like built-in language features. OSVVM has grown rapidly during the COVID years, giving us better capability, better test reporting (HTML and Junit), and scripting that is simple to use (and works with most VHDL simulators). This presentation shows how these advances fit into the overall OSVVM Methodology.

In her talk, Claire will discuss recent developments in open-source verification tools. Claire will briefly present equivalence checking with Yosys (EQY) and mutation cover with Yosys (MCY), and will highlight potential future directions.
