A primary benefit of configurable logic is the number of Boolean functions represented. Generally, the inclusion of control logic occurs towards the end of the project. Only after the key chipset decisions have been made does it become clear which glue logic functions are required. In the past to obtain the correct function, some stock of all standard functions had to be kept onsite. With configurable logic one device represents several standard and non-standard functions, thus reducing the number of different devices required in stock, and in the product bill of materials. By using non-standard functions it is possible to replace two individual devices with a single dual configurable IC. Part of the release process of a product is component qualification. If an application uses a NAND gate, a buffer, and an inverter it will require three separate qualifications. Configurable logic can support up to nine individual Boolean functions; therefore, one qualification could replace nine or more non-configurable components.
