01 Notes on Digital Systems

Regularity• Regularity is also useful in the design process– When decomposing a design attempt to form regular structures• Regularity is particularly useful when considering thelower-level (layout issues of a design)– E.g. memory design which is made from a ‘tile’ of similar cellsconnected together– If we design a single cell, then all that is required is to replicatethe cells to form the complete memory array• Datapaths also benefit from regularity– e.g. Adder21
