- Layout design rules describe how small features can be.
- how closely the features can be reliably packed in a particular IC
manufacturing process. - Industrial design rules are usually specified in microns.
- This makes migrating from one process to a more advanced process or a different foundry’s process difficult because not all rules scale in the same way.
- Therefore Mead and Conway proposed the single parameter LAMBDA.
- Therefore we have lambda based design rules.
- Lambda is generally half of the minimum drawn transistor channel length.
- This length is the distance between the source and drain of a transistor.
