I have been designing embedded system for several years. yet I haven't found good books on develop method, and how to represent the system in diagram so that I can gradually break a big taks into small block. any one can give me some suggestion? (books or standard or any other things?) stoic
Yourdon Structured Analysis and Structured Design (SA/SD) can be applied, though this is probably somewhat passe these days. UML is the current methodology du jour MS Visio has support for these. Although it can be done manually, you don't really get the main benefit without tool support.
