Patent number: 8581618Abstract: A system provides for the distribution of intellectual property logic blocks from a source to a user wherein the user may use the logic blocks during development but is prevented from using the block in production without permission. A sensor is connected in parallel with a first signal from the block and in series with a second signal from the block. When activity on the first signal exceeds a predetermined count, the output of the second signal is corrupted. In some embodiments all such sensors are connected to an aggregator which allows all blocks to continue to operate until all of them have exceeded their predetermined activity count. A state machine compares the values of two keys, one stored within the block, to another value stored in the state machine controller, and allows the block to be used in production if the key values coincide.Type: GrantFiled: February 14, 2012Date of Patent: November 12, 2013Assignee: Social Silicon, Inc.Inventor: David Fritz
