Advanced ASIC (Application Specific Integrated Circuit) development today requires complex and expensive design tools, leading-edge process technologies, and experienced engineering teams. Some large companies can commit the resources needed to acquire the expertise, support a sizable design team, and invest in the complete tool chain and development flow, all the way from circuit design to Graphic Data Systems (GDS) and beyond. This option, known as Customer Owned Tooling (COT), is a good choice for companies that can amortize costs over many products that are manufactured in high volumes for broad markets.
