2、e “Logic Design”. The goal of design is to Build System. Digital Design is engineering, and engineering means “Problem Solving”.數(shù)字設計是工程，工程意味著解決問題 Only 5%-10% is the Creative part of Design. Much of the rest is just “Turning the Crank”.只有5%10%是設計的創(chuàng)新部分，剩下的只是實現(xiàn)構想而已Important ThemesGood tools do not guar

3、antee good design, but they help a lot by taking the pain out of doing things right.好的工具并不能保證好的設計，但它能在正確完成設計工作時大大減輕你的勞動。Digital circuits have analog characteristics. Know when to and when not to worry about the analog aspects.數(shù)字電路具有模擬特性。要知道何時應該何時不應該考慮模擬特性。Document your designs, use consistent coding

4、, organizational and documentation styles to make them understandable to yourself and to others.做好設計文檔，用一致的編碼，組織結構和文檔風格，以方便自己和他人對設計的理解。Design for minimum cost at the system level, including your own engineering effort. Design for testability and manufacturability.在系統(tǒng)級進行最小成本設計，包括自己的工程勞務成本。設計可測試性和可制造性
