2.2.1 Standard cell based ASIC design
Initially RTL (Register Transfer Language) description of the design is written. Then it is synthesized based on technology specific Standard cell libraries. Standard Cells are custom designed and then inserted into a library. These cells are then used in the design by being placed in rows and wired together using ‘place and route’ CAD tools. Some standard cells, such as RAM and ROM cells, and some datapath cells (e.g. a multiplier) are tiled together to create macro cells.
