CMOS Layout Layout design rules describe how small features can be and how closely they can be reliably packed in a particular manufacturing process. Minimum distance rules between device layers eg polysilicon metal metal metal diffusion diffusion and minimum layer overlaps are used during layout Layout design rule checker DRC automatically verifies that no design rules have been broken Note however the use of Lambda is not optimal but supports design reuse. Layout design rules are introduced in order to create reliable and functional circuits on a small area.
Main terms in design rules are feature size width separation and overlap. Outline CMOS Gate Design Pass Transistors CMOS Latches Flip-Flops Standard Cell Layouts Stick Diagrams CMOS Gate Design Activity. Design Rules Jan M.
Our PowerPoint layout design templates can be used to make good presentations in a matter of minutes from project timelines list slides and even diagrams depicting a process. Layer rules unique spacing and specific widths for controlled impedance routing. For working professionals the lectures are a boon.
Design rules does represent geometric limitations for for an engineer. Transmission line is a trace and has a distributed mixture of resistance R inductance L and capacitance C. Width of pMOS should be twice the width of nMOS.
Design rules based on single parameter λ.
