If you have been following VSDOpen for the last 5-years, the theme has been maintained – What VSD did last year and what VSD will do next year
VSDOpen conference is an attempt to bring out some cutting-edge activities especially around open-source EDA with a special focus on skill development using open and proprietary tools. VSDOpen also focuses on milestones achieved by VSD in the past year, and some interesting projects which VSD will be working on in the next year. It’s like the VSD Annual Hands-on meeting where everyone is invited for free and allowed to rate us for our work 🙂
VSD – IIIT Bangalore – Unique example of industry-academia collaboration – 12 chip tapeouts in 2 months
VSD-IIIT Bangalore to set a unique industry-academia model for all colleges across India regarding how tapeout-oriented ASIC design courses can be a part of a full semester curriculum, given the amount of flexibility for curriculum change and mapping to latest industry needs. And thanks to Google/Skywater/efabless for opening up the foundry information, due to which we were able to provide chip design and manufacturing experience to a whole cohort.
Traditional pieces of training have taken an orthogonal shift, post-release of open-source EDA tools and SKY130 foundry. This has brought a huge opportunity for semiconductor ed-tech companies like VSD to close a wide gap within many training companies that have shifted their curriculum from theoretical PDK to real PDK. If you are a student, who is reading this email, do not panic if you are not aware of PDK. This is something which we are covering in the workshop.
The different projects which we have here are 1) modifying RISC-V core so that it recognizes all these instructions to a vector accelerator 2) vector accelerator itself is decoding vector instructions and managing the execution and retirement of these vector instructions
In a nutshell, the project really is to build a Verilator Verification environment i.e. a structure in which we can set up testbenches that are executed with Verilator. The thing which is interesting in this project is we are going to tie that Verilator piece with a golden model arithmetic library and that is going to be something that you can publish as nobody else in the world has that
It’s a Verilator Testbench environment that uses an online arithmetic library to generate the right bit pattern. We are not using randoms, but we are using a Golden model. If you progress from ALU to a vector accelerator, you will have a vector lane, vector register file, vector load/store unit, vector instructions.
