@esden I am curious, what are your plans and what SW base do you intend to use? STCube, #NuttX, #Zephyr, #RTEMS or something else? May it be, there can be something in our portfolio to port or use as the example.

@brixmeister Matyáš Bobek has defended his thesis FlexCAN Controller Emulation for QEMU last Wednesday. Related git https://gitlab.fel.cvut.cz/bobekmat/qemu-flexcan. I hope that he finds time for mainlining in next month. I have submitted CTU CAN FD #CAN emulation for review to #QEMU community but it seems that FPGA support for IP cores which could be mapped into FPGA regions is not understood/welcomed yet.

We have a new home for community discussion around Yosys!

https://yosyshq.discourse.group/

Join us there for questions, support and discussion about our open source EDA tools.

Prof. Kip Thorne even presented 43 years of history leading to the proving of gravitation waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO). He has documented how this has been possible even thanks to cooperation with scientists in Prague and the Soviet Union who have been forced to withstand Stalinism, Soviet occupation of Czech Republic in 1968 ending the Prague Spring, making another obstacle for cooperation, etc. His last slide was less optimistic when compared with Prof. J. Podolský outlook ( Gravitační vlny po 10 letech, a co bude dál?) for Einstein Telescope, VIRGO, LISA, and more bright future based on cooperation of the governments, funding, and scientists worldwide.

@frankenswine @LainTrain If you want to start learning #riscv ISA then the basic introduction to the minimal set of RV32 instructions can be found at our #comparch course tutorial page https://cw.fel.cvut.cz/wiki/courses/b35apo/en/tutorials/03/start .
You can test the code on the #QtRvSim single-cycle simulator setup and then follow to the pipelined version. The simulator can be installed on GNU/Linux, Windows, MAC OS and online version is available at https://comparch.edu.cvut.cz/ . The related lectures are available at https://cw.fel.cvut.cz/wiki/courses/b35apo/en/lectures/start . There are even advertisements free accessible recordings available at https://vhsky.cz/w/p/8Ejstt3Tfh8mWGcjQcEL2S

The new book how to build #riscv processor for #comparch courses is on the horizon (ETA later H2 2025) RISC-V System-on-Chip Design by D. Harris, J. Stine, R. Thompson, S. Harris. It has been presented at the RISC-V International Academic and Training SIG meeting. The recording of the session is available on YouTube https://youtu.be/Qyq5nHUDt4g The related configurable RV32I to RV64IMAFDCB core and Wally SoC sources https://github.com/openhwgroup/cvw

Možná už tu někdo dával, ale @ppisa mě upozornil na #petici za open-source ve státní správě. Podpisů je tam pomálu a přitom petice je podle mě dobře formulovaná. Zvažte podpis. Děkuji, konec hlášení.

The #QEMU on the Linux host emulation of CAN/CAN FD bus for #nuttx presented in the article Host-Based Development with Apache NuttX – CAN Network Simulation by Mateusz Szafoni is using lot of the components from our #canbus list https://canbus.pages.fel.cvut.cz/. I have even prepared CTU CAN FD QEMU emulation variant for SoCs without PCI/PCIe bus on the branch net-can-ctucanfd-platform and my student, Matyáš Bobek has just finished his thesis adding iMX6 FlexCAN emulation into QEMU, code is available on the flexcan branch of his QEMU repository.

I am very thankful for these open-source tools as well. For my lectures and other editing, I even use the trick to render the initial combination of video, sound, and screen by Kdenlive into a raw mp4 file and then use VLC https://www.videolan.org/vlc, which is much more performant in fast searching and playback even at peed 15x. Till the speed 3.5x, it allows even to check for audio problems. Then, I use the times of the required corrections and cuts in the Kdenlive. As for the recording, I combine multiple computers running OBS, one for the camera and the other for the screen, where I usually present with BigBlueButton https://bigbluebutton.org/, which is great for making notices and drawings into PDF and other format presentations. It allows even live online access for students, which has been crucial during COVID. I use a Wacom ONE tablet https://www.wacom.com/en-us/products/pen-displays/wacom-one for annotations and drawings.
The results are available, for example, on https://vhsky.cz/c/ctucomparch/videos and the Czech Technical University in Prague YouTube channel.

If you want to learn #RiscV basic principles yourself or use it in your computer architectures #comparch basic classes, then you can use our really open and fully shared resources, no registration required for experimenting online https://comparch.edu.cvut.cz/, downloading #QtRvSim packages for all major desktop operating systems #linux, #macos, #mswidows and obtaining lectures with the sources https://cw.fel.cvut.cz/wiki/courses/b35apo/en/lectures/start and recordings on YouTube and even advertisement-free community PeerTube instance VHSky.cz. We offer even online training and and competition site https://comparch.edu.cvut.cz/online-tools/webeval/. In this case, we store SHA1 of your e-mail only for purpose to allow participants to reset their password. So again we do not intend and even cannot use your registration for advertisement for paid courses etc.

Thanks for notice, I think that this and The Microsoft-Dilemma - Europe as a Software Colony should be mandatory to study for #cvut and may it be even #cesnet IT captains. Exactly questions to resiliency to the temporal Internet connection lost and even possibility of hostilities after steering to total dependance on MS technologies have been part of my request for some analysis in the official CTU IT issues trackers. But all tickets have been closed by Mgr. Stanislav Kalina (Microsoft Technical Specialist in the Czech Technical University in Prague organization) as totally unfounded nonsense and FUD spread.

@pavel @pabloyoyoista My personal feeling is that people are getting too much sensitive (including myself sometimes) and that they should be taught that technical opinion and fact should be expressed without hiding even hurting facts. But on the other hand it should be expressed and made clean that it is not personal attack etc. On the other hand I agree that programming and even all complex technical decisions are about feeling and taste because no human or even ML system has enough memory and computational power to do real deep search in all alternatives. The state space of possible solutions is to large. But I have my personal feeling (yes again that wold), than it is much worse to attempt to hide facts or be afraid to pass forward what you believe are facts. Then everybody needs to analyze if that what you say is what you mean or if you say it that way that you afraid etc… So nobody can build idea about different persons thoughts about his, her code etc… So I consider that it is right when I sometimes feel injustice caused to me or I cannot find same point of view as others. But it should not lead to lies, defamation etc. In the worst case, the result should be agree to disagree which can lead even to project fork or move to another project. May it be, the opinions can be communicated later and advantage of joining the forces prevails losts required by compromises. (Excuse my English, may it be it can shift my idea a little from what I mean and “feel”).

Open-Source Chips for Europe
https://open-source-chips.eu/

"We already see rising interest from many EU stakeholders, with increasing investments into open-source chip design, especially in open source IP development (e.g. RISC-V cores), and open source EDA tools.

One additional critical barrier remains toward the end-goal of building real open-source chips, especially for prototyping and education: namely, streamlining the access to open source chip production facilities (foundries) is essential."
