-Fri,10:30,Normal,Opening,FOSSi team,,,
-Fri,10:40,Normal,Using Clash to enable logically synchronous data centers,Christiaan Baaij,Tool,,"The fact that all the computers and switches in a data center are mostly independent and asynchronously operating entities can cause issues. This includes a wide variance in end-to-end latency (“lag spike”), to efficient compute resource usage; and on top of that: all the buffers that are all over the place are consuming a lot of energy. Imagine, however, what would happen if you could treat your entire data center as a synchronous digital circuit: latency becomes deterministic, scheduling applications for efficient resource usage becomes easier, and you can drastically reduce buffer sizes. This is what the Bittide project, https://www.bittide.io/, aims to achieve: to bring ‘logical’ synchrony to data centers. This talk will explain what ‘logical’ synchrony is and how we used Clash, https://clash-lang.org/, to build the hardware support to enable it."

This presentation will mainly be a live demonstration of the project running Debian on FPGA, exposing the level of performance achievable on such system including boot, userland, some demos and finaly a few slides."
-Fri,11:40,Normal,FazyRV: A RISC-V Core that Scales to Your Needs,Meinhard Kissich,Core,1,"FazyRV is a scalable RISC-V core that can be synthesized into a (1-)bit-serial, 2-, 4-, or 8-bit-serial implementation to fulfill your performance requirements with the least area (resp. resources) demand. FazyRV provides manifold variants to adapt to the target technology by, e.g., avoiding dual-port BRAM at the cost of an additional clock cycle. Contradictory to hand-optimized cores at the gate level, FazyRV tries to avoid manual low-level optimizations to increase readability and simplify adaptations. This talk gives an insight into the open-source FazyRV core and its design objectives. We show how the area demand scales, answer why there is no 16-bit variant, discuss how the performance can be improved, and outline possible extensions to improve the current FazyRV design."
-Fri,12:00,Normal,A very small cross compiler for OpenRISC and maybe your homebrew processor,Jörg Mische,Tool,2,"PunyCC is a cross compiler for a very small subset of C. Only one source file, no preprocessor, no structs, no floating point and only one datatype that can be used as unsigend int or pointer to char. Due to these simplifications the compiler source code is very small and can easily be adopted to a new target instruction set. So far PunyCC supported 4 architectures: ARM Thumb-2, RISC-V, x86-32 and WebAssembly. It can compile itself and thus provides cross compilers from any of the instruction sets to any other. This talk presents how easy it is to add OpenRISC support to PunyCC. Use it as a blueprint for porting PunyCC to your own special instruction set."

The talk will also present the SystemRDL integration with Renode speeding up generation of the co-simulation verification environment, as well as Caliptra’s entry in Antmicro’s System Designer which lets you explore the SoC’s structure, RTL and verification artifacts from a block diagram perspective."
-Fri,13:50,Normal,The future of FuseSoC,Olof Kindgren,Tool,2,"While individual projects like Linux and GCC paved the road for open source software success, it can be argued that the thing that really enabled scaling up development of Linux-based solutions was the idea of package management. Having a common way to install software and describe their relations made it possible to rapidly create custom systems. The same can be said for language-specific package managers like pip for Python or Cargo for Rust.

-Sat,12:10,Normal,BYOL (Build Your Own Linter) - UVMLint for IEEE-UVM core code development,Ajeetha Kumari Venkatesan,Verification,1,"UVM is the most adopted design verification methodology in the field of ASIC and FPGA designs. Lint and static checking of code has proven to be very effective in projects that have wide user base, longer lifetime and distributed developers. During the recent UVM IEEE 1800.2-2023 release cycle, an observation was made regarding the potential application of a custom UVMLint solution to lint the UVM Base Class Library (BCL) as it gets developed, updated etc. We at AsFigo have developed custom rules for linting UVM BCL code on top of PySlint, an open-source SystemVerilog testbench linter. We intend to offer this as an opensource lint package to the UVM IEEE committee and to the general audience via GitHub. The eventual goal is to have these rules as gatekeepers via GitHub actions so that any future code addition to the UVM BCL is free from common pitfalls. Based on early brainstorming, below are some of the sample lint rules that are relevant to the UVM BCL codebase: • Avoid race condition around ""static const"" (use localparam instead) • Avoid one-liner conditional statements: o if (cond) $display (""cond""); o if (cond) .. else $display (""Else cond as single line""); o case..endcase • Avoid one-liner code in loops: o for, repeat, while, do..while, foreach • Use enadlabels for elements such as endclass, endfunction, endtask etc. • Flag non-virtual methods Typical UVMLint rules for a VIP user would be quite different from the requirements of UVM BCL. These rules are tailored for UVM BCL codebase. As an example, a typical UVMLint rule for a VIP would be: • Check that agent is reusable by ensuring that active components are guarded with a conditional check to is_active == UVM_ACTIVE Such a rule is quite useless for UVM BCL as it provides the base class library for tens of thousands of engineers around the globe using this library to build VIPs, verify their IPs, systems etc. In this talk we show how we approach this cusotm UVMLint development with sample Python code, tests and results. A snapshot of UVMLint findings on latest IEEE 1800.2-2023 codebase is below: ** Violation count by Rule-IDs ** DBG_CL_MISSING_ENDLABEL : 286 DBG_METHOD_MISSING_ENDLABEL : 1899 DBG_FN_MISSING_ENDLABEL : 752 DBG_AVOID_ONE_LINER_IF : 73 DBG_AVOID_ONE_LINER_ELSE : 88 RACE_NO_STATIC_CONST : 8 REUSE_NON_VIRTUAL_METHOD : 1407 --- UVMLint Concise Report --- Total number of rules violated: 7"

Analog/RF circuit design is usually not very complex, but often requires knowledge of actual device physics and parameters. It also requires many simulation to find good circuit solutions and robust designs. Open-source tools for parts of IC design flows have been available for a long time, but only lately, open process information (process design kits, PDKs) has been made available, which make fully open-source design flows for circuit design and commercial foundry fabrication possible. But how well suited for exploring and teaching the principles of analog/RF IC design are open-source tools and PDKs compared to commercial tools and closed PDKs? And can they be used for prototype chips in research projects? In the presentation, I will describe how we created a PhD course (also suitable for master programs) on analog IC design, addressing the design chain, tools, and everything you need to know to design and have chips fabricated at a foundry using only open-source tools and PDKs. A comparison with the commercial tools currently used in education and industry will also be made."

-Sat,14:40,Normal,Digital Signal Processing: Modeling with Julia,David Hossack,Tool,,"Digital signal processing (DSP) paths are usually simulated at a high level using C or MATLAB/Simulink models to confirm basic functionality and to assess whether signal processing requirements such as frequency response and signal-to-noise ratio are being met. Complex signal processing paths consist of cascades of sigma-delta modulators, filter stages, mixers, modulators, demodulators etc each of which have a corresponding high level model. A very simple framework has been developed in Julia to enable combinations of DSP stages to be evaluated. This talk will discuss the experience of using Julia to combine models written in Julia and C, and designs written in Verilog (using Verilator) in industrial settings over many years. The principles should also be applicable to C++ or Python evaluation environments."

Each library provides independent capabilities, allowing selective adoption and a learn-as-you-go approach. Whether using directed or random testing, OSVVM facilitates writing concise and readable test cases for both simple unit/RTL tests and complex, full-chip or system-level FPGA and ASIC tests. OSVVM provides VHDL with verification capabilities that rival SystemVerilog + UVM. These include transaction-level modeling, verification components, co-simulation with software, randomized test generation, self-checking test support, verification data structures, comprehensive test reporting in HTML and text, and synchronization primitives. With OSVVM and a good team lead, any VHDL engineer can do verification – and have fun doing it. OSVVM grew rapidly during the COVID years, giving us better capability, better data structures, better test reporting (HTML and Junit), and scripting that is simple to use (and works with most VHDL simulators). This presentation will show how these advances fit into the overall OSVVM Methodology."

+Sat,12:10,Normal,BYOL (Build Your Own Linter) - UVMLint for IEEE-UVM core code development,Ajeetha Kumari Venkatesan,Verification,"UVM is the most adopted design verification methodology in the field of ASIC and FPGA designs. Lint and static checking of code has proven to be very effective in projects that have wide user base, longer lifetime and distributed developers. During the recent UVM IEEE 1800.2-2023 release cycle, an observation was made regarding the potential application of a custom UVMLint solution to lint the UVM Base Class Library (BCL) as it gets developed, updated etc. We at AsFigo have developed custom rules for linting UVM BCL code on top of PySlint, an open-source SystemVerilog testbench linter. We intend to offer this as an opensource lint package to the UVM IEEE committee and to the general audience via GitHub. The eventual goal is to have these rules as gatekeepers via GitHub actions so that any future code addition to the UVM BCL is free from common pitfalls. Based on early brainstorming, below are some of the sample lint rules that are relevant to the UVM BCL codebase: • Avoid race condition around ""static const"" (use localparam instead) • Avoid one-liner conditional statements: o if (cond) $display (""cond""); o if (cond) .. else $display (""Else cond as single line""); o case..endcase • Avoid one-liner code in loops: o for, repeat, while, do..while, foreach • Use enadlabels for elements such as endclass, endfunction, endtask etc. • Flag non-virtual methods Typical UVMLint rules for a VIP user would be quite different from the requirements of UVM BCL. These rules are tailored for UVM BCL codebase. As an example, a typical UVMLint rule for a VIP would be: • Check that agent is reusable by ensuring that active components are guarded with a conditional check to is_active == UVM_ACTIVE Such a rule is quite useless for UVM BCL as it provides the base class library for tens of thousands of engineers around the globe using this library to build VIPs, verify their IPs, systems etc. In this talk we show how we approach this cusotm UVMLint development with sample Python code, tests and results. A snapshot of UVMLint findings on latest IEEE 1800.2-2023 codebase is below: ** Violation count by Rule-IDs ** DBG_CL_MISSING_ENDLABEL : 286 DBG_METHOD_MISSING_ENDLABEL : 1899 DBG_FN_MISSING_ENDLABEL : 752 DBG_AVOID_ONE_LINER_IF : 73 DBG_AVOID_ONE_LINER_ELSE : 88 RACE_NO_STATIC_CONST : 8 REUSE_NON_VIRTUAL_METHOD : 1407 --- UVMLint Concise Report --- Total number of rules violated: 7"
