FOSSi Dial-Up is the premier online event around Free and Open Source Silicon and EDA tools. It features selected speakers from the rapidly developing FOSSi ecosystem.

Tim Ansell - Fully open source manufacturable PDK for a 130nm process

Date: Tuesday, June 30, 2020
Time: 16:00 GMT (time zone converter)


The SkyWater Open Source Process Design Kit (PDK) is a joint project of Google and SkyWater Technology Foundry to provide a fully open source PDK.

In this event, Tim Ansell will outline the collaboration and the goals of the project. He will get into the technical details of the PDK and outline the roadmap of the project.

  • Mohamed Shalan - OpenROAD on SkyWater 130nm

    Tuesday, July 28, 2020 16:00 GMT

    Unlike the wider software world, Electronic Design Automation (EDA) open-source landscape has been fragmented for a long time, requiring significant effort and knowledge in a variety of disciplines to assemble a working ASIC flow. This has changed with projects such as Qflow and OpenROAD that aim at developing open-source toolchain for digital layout generation from RTL.

    OpenLane is an automated RTL to GDSII flow based on available opensource EDA tools configured/tuned for the SkyWater 130nm PDK. OpenLane main objective is to generate a clean layout from RTL designs in less than 24-hours with zero human interventions. OpenLane has been used, successfully, to tape-out a family of test chips (striVe).

  • James Stine - Designing new 130nm cells for SkyWater 130nm

    Tuesday, August 25, 2020 16:00 GMT

    Existing design flows and tools require excessive design costs to achieve the power, area, and performance requirements of complex system-on-chip (SoC) solutions. Consequently, the semiconductor industry needs high-level synthesis tools that provide the ability to quickly develop and accurately evaluate complex SoC solutions. These tools should provide accurate area, delay, and power estimates from high-level SoC architecture descriptions. They should also provide support for a wide variety of components including embedded memories, mixed-signal designs, custom and standard cell circuits, high-performance/low-power processors, and communication structures, such as buses and on-chip networks. In addition to being well documented, easy to use, and publicly available, the design flows should work in conjunction with industry-standard design tools.

    This project will provide publicly-available high-level synthesis tools for complex SoC solutions for the SkyWater 130nm. The tools improve productivity by allowing SoC designers to quickly develop and evaluate high-performance, low-power systems. They also provide an improved understanding of area, performance, and power tradeoffs in SoC designs. The instructional materials and sample SoC architectures provided are useful for engineers, edu- cators, and students, who are new to the area of SoC design, as well. Most importantly, the tools are designed to be free and open-source software (FOSS) and integrate with tools from eFabless as well as other open-source endeavors.

  • Matt Guthaus - OpenRAM on SkyWater 130nm

    Tuesday, September 22, 2020 16:00 GMT

    OpenRAM is an open-source Python framework to create the layout, netlists, timing and power models, placement and routing models, and other views necessary to use SRAMs in ASIC design. OpenRAM supports integration in both commercial and open-source flows with both predictive and fabricable technologies.
  • Tim Edwards - Using Magic for DRC checks on SkyWater 130nm

    Tuesday, October 20, 2020 16:00 GMT

    Magic was long known as the layout tool that does interactive DRC. Which it still does! Plus a lot of new tricks that are less well known. With the decline of SCMOS, there has been no way to demonstrate its capabilities. With the new SkyWater open PDK, we can show how magic does interactive and batch DRC; density, stress, latchup, and antenna rules, and much more.
