電腦輔助電路設計實習先進 Schematic Design - Introduction PCB設計成長學習營 Schematic Design is the graphical representation of a circuit. It does give designer a relatively good idea on the design as a whole. Doing a schematic therefore required a good precision tool which will later link to a PCB layout/routing tool. The CADSTAR Schematic Design Editor keeps the design integrity and pass it on to the PCB, hence made it a very powerful circuit capture tool to prevent from unintentional 電機工程系 mistakes. The training will take designers to see how the design editor 陳正 義 教 授 benefits to overall design of the capture and the link with PCB design.

• In this chapter, you will learn how to set up Variants in both Schematic and the • For example, if you change a component on a Variant, the PCB designs. During this course you will learn how: replacement must have the same 'footprint' (i.e. dimensions, – To set up a ‘hierarchical structure’ of Variants for a design at number of pads, shape of pads, pad stacks, etc.) as the the Schematic stage; component being replaced. – To specify ‘Not Fitted’ components on a Variant design (Schematic); • An acceptable modification to a Variant is to replace existing – To specify different Parts on a Variant design (Schematic); components with new Parts which have the same copper profile – To transfer Variant information from a Schematic to a PCB (i.e ‘footprint’). This is shown below: Design; – To set up Variants on the PCB Design; – To check the validity of Variants; – To generate a Parts list for a Variant.

Introduction To Variants Introduction To Variants • CADSTAR enables you to generate Variants of a 'master' • Although the Variant Component shown above uses an identical design without having to maintain separate files for each Variant. footprint (i.e. component shape) it is a different Part. For example, you would use it in situations where you need to • The Outline of the Variant component can be displayed in a different provide designs that are suitable for the different power supplies colour, thus enabling you to easily identify it (Colours option). In PCB around the world. Design you need to specify on which Non-Electrical layer the Variant colour for the Variant Symbol/Component is to be displayed (Layers • Copper Profiles … option). – A Variant is only valid if its copper profile is identical to the • Not Fitted Components copper profile ofthe Master. In other words, the shape, size – You can also create a Variant in which selected components are classed as and position of the component pads,route segments, and ‘not fitted’. The pads are still displayed - thus maintaining the same copper copper areas of the Variant must be identical to that on the profile - but the components are displayed as ‘not fitted’ with a distinctive outline (the dotted outlines shown next) Master.

CADSTAR SI Verify – Conclusion CADSTAR 3D • The simulation of Signal Integrity for High-Speed Digital Signals is absolute necessary/mandatory (sometimes demanded by the silicon vendors).
• Avoid using the autorouter without Controlling (and Constraining) the Signal Integrity aspects upfront.
• Diffpairs and multi-gigabit data links are becoming mainstream.
• A High-speed implementation process is needed for first pass success, for future projects customers should have a Constraint Management System.

Adherence to design rules can format). be checked without the user having to access the mechanical design system. • The need to create 'right-first-time' placement to avoid unnecessary design iterations is driving demand for solutions that include 3D checking. Eliminating mechanical clashes early in the design process means that design changes can be tested before financial commitments to enclosures are made. As the use of custom enclosures often involves high tooling costs, early 3D checking can help avoid expensive errors.
