EspoTek’s Labrador is a tiny yet powerful device that transforms a PC into a fully featured electronics lab, complete with an oscilloscope, signal generator, logic analyzer, multimeter and power supply. Qucs (Quite Universal Circuit Simulator) is an integrated circuit (IC) simulator which allow to setup a circuit with a schematic entry graphical user interface (GUI) and simulate the large and small-signal (DC, AC, S-parameter, Harmonic Balance and noise analysis) of the microelectronic circuit. Both hardware and software are 100% open-source (FOSS). Both tools will be used to illustrate complete flow of the measurements, characterization and SPICE modeling of the semiconductor devices for EDA IC design applications. EspoTek’s Labrador and Qucs cointegrations thru embedded Octave scripts will be discussed as well.

I will introduce the basis of simulation, the basic "SPICE" methods (DC, AC, and transient analysis), mixed-signal (event driven) simulations, and "Fast-Spice". Also, some derived methods, including Fourier analysis, Harmonic Balance, and Periodic Steady State will be introduced. Along with this, I will review where the Free simulators (Gnucap, Qucs, NGspice, Xyce) stand.
I will also present the plugin based architecture of Gnucap, and how it encourages contributions and fast deployment without sacrificing quality of the base work.

You are a software guy, having heard of VHDL or Verilog but never used it ? In this 25 min tutorial, you will learn the basis of hardware design and how to write a simple FPGA design using only FOSS tools. (This tutorial is not about PCB design, but reprogrammable chips design)
This is the same talk as the one of FOSDEM'17. As the room was full, some people were not able to attend so I propose to do it again.

There is a challenge in making this technology accessible and easy to use by everyone.In this talk I will present the project Apio, a multiplatform cli toolbox, and Icestudio, a high-level visual editor that allows to create and synthesize graphic designs into Open Source FPGAs.Connecting high-level description languages with real hardware implementations enables a lot of new ideas, new research branches, new capabilities. We have begun to explore the surface but there is still a long way to go!

Thanks to the Icestorm project we all have open source FPGAs. We have develop both Free/libre hardware and software for making it very easy for the non-tech people or kids to start learning and playing with digital circuits. We will show in a demo how the Icestudio and the Icezum Alhambra FPGA board works. With very few clicks the digital circuits are synthesized and uploaded into the FPGA. It opens the way for teaching hardware thinking and digital circuits without pain and learning concepts while building circuits

The talk will start with a summary and vision of the Chips4Makers project.
In a second part of the talk the current state of the used tool chain will be discussed. With the Retro-uC project this tool chain is tested and it will be presented what worked and what is candidate for improvement. I do hope I can get feedback from the public and get more inspiration to improve the toolchain in use for future user projects.
The Retro-uC chip itself - a microcontroller with the right instruction set for a retrocomputing enthusiast - is discussed in a talk in the retrocomputing devroom.

However, as trendy as it may turn, there is no viable Electronic Design Automation (EDA) toolchain that allows to design ICs in 3D. Our work aims at developing tools that could be used in standard 2D EDA chains to deal with 3D ICs. Such tools will automatically transform any 2D design into an optimized 3D architecture by extracting a graph from the DEF file coming out from 2D synthesis and place&route flow. Afterward, this graph can be partitioned automatically using state-of-the art graph partitioning tools.
In order to create the toolchain, we developed a custom DEF parser to answer specific and limited needs that existing solutions such as Verilog-perl or PyVerilog did not allow. The software scans the DEF to find all the gates, pins and nets in the given design. When analyzing nets, it also parses the routing information to determine the total length of the net, which will be needed in the partitioning phase.
In parallel with the DEF parsing (design input), the LEF technology file (technology input) is also parsed to fetch the characteristics of the gates that will be used later on in the clustering and partitioning steps.
Once the design has been parsed, it can be clusterized to reduce the problem complexity and the output is formatted to extract the underlying hypergraph.The extraction makes use of standard Python structures such as dictionaries in order to quickly find links in the design and establish references between the vertices (i.e. clusters or gates) and edges (i.e. nets). When building the hypergraph, some metadata are linked to each vertex/edge (e.g. area, power, total length, total connections) to later set their weights that will be needed in the partitioning phase.
As soon as the design has been converted into a hypergraph, it is formatted in such a way so that it can be fed to the hMETIS package. Using the weights sets extracted during DEF/LEF parsing phase, hMETIS partitions the graph. The output is processed into TCL directives that are then interpreted by a proprietary tool handling the 3D P&R, or they can be used to automatically partition the post-synthesis gate-level netlist and thus be used with any EDA flow, including the open-source ones.

The goal of the LibrePCB project is to create a modern, powerful and easy-to-use EDA package for everyone. The project is still in a quite early development stage, but is already usable for creating simple PCBs.
In addition to a short live demonstration, I'd like to talk about the motivation behind LibrePCB, explain some of its concepts and what plans we have for the future.

If this isn't clear, for an example of exactly what the problem is, try an Internet search for "Laptop trackpad supplier". Did you find one? Did you find a source of trackpads for use in that laptop that you're thinking of designing? Or did your search queries instead get completely and utterly swamped with thousands upon thousands of aliexpress pictures of the EXACT SAME Apple Trackpad for a 13in Macbook Pro?
What about LCDs? Do you even know what type of LCD is commonly available right now? Were you aware that MIPI is Cartelled? Or that the people telling you that eDP is "The Future" are trying to push a much higher-power-consumption design at you and they forgot to invite China-based Manufacturers to the closed-door meeting. How can you actually find which LCDs are commonly manufactured and available in Shenzhen, so that you can begin the design right now before you take that expensive trip abroad.
And what about components? If you've looked on taobao or aliexpress, you'll know that many of them are rip-offs, there's absolutely no datasheets, the vendors make pittance so they're extremely unlikely to answer your questions... so what actual use is this resource, to anyone?
This talk will help answer the paradox of bridging the gap between Shenzhen market prices and the Western and Libre mindsets for hardware design, allowing attendees to take proper advantage of the lower pricing of Shenzhen-sourced parts, and to avoid the nightmare scenario of designing a PCB only to find that its parts went End-of-Life in the Shenzhen markets many years ago, and that the last remaining parts available must be bought from Digikey and IMPORTED (back into China from where they originated!) with a whopping lead time and huge import tariffs of up to 40 percent.

As it targets a sepcific user and application group it also relies on additional data on top of traditionally used positional data. This presentation is about an effort to create a hard- and software platform capable of collecting the needed data for the OpenSeaMap project. We share early results yield with a prototype implementation of the proposed platform.
