Hello KiCad community!
I wanted to share a plugin I just developed: Netclass Information Plugin. Basically, it checks the netclasses of your PCB, calculates the length of each net and then generates DRC (rule ...) rules with the maximum length found for each of the netclasses. It also offers a panel to filter which netclasses you want to see and makes it easy for you to copy that block of rules and paste it into your DRC configuration.
It doesn’t do anything automatic in KiCad files (to avoid problems), but it does show you all the info in a simple way. My idea is that anyone can extend it or adapt it to their needs, so it is under an open license and the repository is available on GitHub.
If you are interested, stop by my repo, try it and let me know what you think, thanks for reading!
