Abstract: This invention pertains to the field of creating incentives for the completion of the design of integrated electronic circuits (chips). Modern chip design use sophisticated computer aided design software (CAD tools). Typically, CAD tools are sold or rented with pricing schemes that restrict the number of copies and usage of the software and are accompanied by a time-based maintenance charge. These pricing schemes do not encourage cooperation and business efficiency. In one embodiment of the invention, a CAD tool vendor receives two payments, one for access to the technology, providing unlimited usage and copies of the software, and a second payment when the technology produces a useful result. This connects vendor payment to the success of the customer. The vendor finds it advantageous to create tools that are easy to learn, easy to use, and with all the necessary functionality.

Abstract: A method for enforcing a contract for a computer-aided-design (CAD) tool is provided. In this method, a first payment for the CAD tool is made in accordance with the contract. The first payment is associated with user access to the CAD tool. At this point, the CAD tool can be used, wherein the computer system running the CAD tool includes criteria for requesting at least one additional payment for the CAD tool. Each additional payment is associated with generating an output. The computer system is responsive to one or more trigger conditions corresponding to the criteria. A payment request is received when an output generated by the CAD tool satisfies a trigger condition. For example, one trigger condition adds a watermark to the output for identifying the output as having been produced by the CAD tool.
