Young-Joon Lee at Google presented a learning-based approach to macro placement, one of the most complex and time-consuming stages in the chip design process. Unlike prior methods, this approach has the ability to learn from past experiences and improve over time. Young-Joon Lee discussed how his team posed macro placement – using Ariane, an open source RISC-V processor – as a Reinforcement Learning (RL) problem and trained an agent to place the cells of a netlist onto a floorplan area. The team also developed a novel edge-based graph convolutional neural network architecture capable of learning rich and transferable representations of the block. This method is capable of leveraging past experiences to become both better and faster at solving new instances of the problem. The objective is to minimize total wirelength under predefined congestion and density targets. Young-Joon Lee showed that for the floorplan blocks of modern accelerator chips, this method can generate high quality macro placements in terms of power, performance, and area in under six hours, whereas the baseline approach requires human experts on multiple iterations and takes several weeks.

» CHIPS Alliance Deep Dive Cafe Talks: Advanced Interface Bus (AIB) Die-to-Die PHY Deep Dive

Date: Aug. 10, 2021

Experts on PHYs, protocols, EDA and heterogeneous integration gave talks on the latest developments on die-to-die interfacing. Read on for more information about this event with Intel and Blue Cheetah Analog Design, Inc.

AIB Deep Dive Kickoff with David Kehlet, Research Scientist, Intel

AXI Protocols for Die-to-Die Interoperability with Nij Dorairaj, Senior Engineer, Intel: Nij covered AXI protocol over AIB and how it enables end-to-end AXI interface across chiplets. He provided details on how AXI4-Streaming and AXI4 signals are mapped over AIB to achieve this with examples. Nij also discussed channel alignment usage with AXI and its necessity for multi-channel protocols.

Die-to-die Standards for 3D Heterogenous Integration with Dr. Farhana Sheikh, Senior Engineer, Intel: Farhana shared a high-level overview of need for die-to-die standards for 3D heterogeneous integration and a review of AIB-3D concept, along with the company’s plans for open sourcing an early AIB-3D specification in 2022.

AIB Chiplet Ecosystem with Martin Won, Senior Member of Technical Staff, Intel: Martin covered how AIB-based chiplets and the AIB-based chiplet ecosystem helps Intel achieve product goals and technology pathfinding to new areas of potential product development.  He also discussed how Intel built the Stratix and Agilex families, including integration of the first non-Intel designed AIB-based chiplets into our FPGA products.

AIB and Chiplet Interface Generators with Krishna Settaluri, CEO, Blue Cheetah Analog Design: Krishna covered how Blue Cheetah’s generators enable rapid configurability of circuits for chiplet interfaces and highlighted the results / verified outputs of the AIB generator.

AIB on Standard Packaging, Lai Guan Tang with Principal Engineer, Intel: Lai Guan covered AIB scaling over different package technologies and the concept of using a common AIB PHY to scale to multiple bandwidth densities.

» CHIPS Alliance Deep Dive Cafe Talks: Verible/UHDM Presented by Google

Date: July 13, 2021

SystemVerilog is one of the most used languages for hardware modelling. The available open source tooling does not universally support the whole feature set yet which can be a limitation for projects considering these tools. This talk covered the CHIPS Alliance’s efforts to provide strong support for SystemVerilog ranging from a compiler frontend using Surelog and UHDM for tools such as Yosys and Verilator to the formatting and linting tool Verible.

Henner Zeller is a software engineer who has been with Google for more than 15 years with a passion for open source and hardware. He had been responsible for the Google web crawler before shifting his focus to improve the open source ecosystem for hardware modelling.

» Dynamic Scheduling in Verilator Presented by Antmicro

Date: June 15, 2021

The presentation discussed the current status of the work towards UVM support in open source tooling. Karol discussed the current state of the ecosystem and the latest milestone – a dynamic stratified scheduler implementation in Verilator, which opens the door to running event-driven simulations in the popular open source HDL simulation framework.

Karol Gugala is an  Engineering Manager at Antmicro, where he is working with open source in various contexts – primarily FPGA and embedded software. Open source enthusiast – involved in a wide variety of FOSS projects.

» Cache Coherent Memory Fabric based on RISC-V

Date: April 16, 2020

Location: Virtual

With RISC-V being an open ISA, this has enabled many open system architectural capabilities. One of these is the cache coherent Tilelink bus. Based on Tilelink, an open cache coherent memory fabric call OmniXtend was developed. This online meetup will discuss the latest updates, support and next steps for this revolutionary architecture.

  • Login & say hello to each other
  • TileLink Introduction – Wesley Terpstra , SiFive
