As part of our EDAcation project, we are building an extension for VSCode to facilitate digital hardware design. We built an FPGA viewer to integrate into VSCode, but since VSCode is essentially just a web browser anyway, we figured why not publish it as a separate website as well? So that's what we did, and you can see the results for yourself on the linked webpage.
You can inspect a variety of iCE40 & ECP5 FPGAs as well as visualize various PnR results. We included some example designs, but if you are familiar with Nextpnr, you can also upload your own.
All data stays local, the viewer runs entirely from within your browser. The chip renderer is written in Rust and compiled to WebAssembly. You can check out the code if you want, all of our projects are fully open source.
Our goal is to make digital hardware design more accessible, and this project fits right in with that mission. Curious to hear your opinions!
