Multi-Channel RulesJust recently I was reading this post on the EEVBlog forum and thought "Ah ha! I've done this before." Should be easy. Famous last words.
So after spending a ridiculous amount of time workign out what the missing step was, I thought I'd better capture it for the next time I want to use it.
You use a multi-channel design in Altium when you have multiples of an identical sub-circuit. QAll you need to do is lay out the one channel, and then you can duplicate the layout by 'Copy Room Formats". This has saved me a ton of time in the past.
