Hello everyone, I would like to know if anyone has advice for, or can recommend resources on, writing high level/system level requirements for PCBs that are part of larger systems? How might one go about organizing the document? For reference: I'm an electrical engineer in company A. I'm designing a controller PCB for an electromechanical assembly designed by mechanical engineers at company B. This is avionics and there are lots of requirements coming from many different regulatory standards and control drawings. Good document organization and "conceptual integrity" is the goal. --=20 Jason White --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
