An apparatus and method for accurately tuning the speed of an integrated circuit, i.e. a computer chip, using a built-in sense circuit and controller are provided. The sense circuit is provided in association with a monitored path. The sense circuit includes a variable delay element coupled to a controller. A data signal from the monitored path is provided to the sense circuit which adds an amount of delay as determined by the controller to the data signal. The delayed data signal and the original data signal are compared to determine if their values match. If they match, then the amount of delay added by the variable delay element is increased. If they do not match, then a previous amount of delay, prior to the mismatch, is output as the slack of the monitored path. The slack may then be used to tune the speed of the integrated circuit.

The invention relates to a speed changer structure and provides a magnetic force coupling adjustable transmission gear box. The transmission gear box is characterized in that: an input shaft (1) is fixedly connected with a 1# conductor disc (4) which is embedded with or attached with a 1# conductor ring (3). An air gap range extension pad (5) connects with a 2# conductor disc (9) and a 2# conductor ring (8). An output shaft (12) is fixedly connected with a magnetic force disc (10). On same circumference of the magnetic force disc (10), a plurality of rotatable rotation round blocks (6) are embedded, and two close permanent magnets (7) with different polarities are placed into each rotation round block (6). S / N polarities of all permanent magnets (7) are in central symmetry with a center of circle of the magnetic force disc (10). The magnetic force disc (10) of the output shaft (12) is positioned between the 1# conductor disc (4) and the 2# conductor disc (9) of the input shaft (1), and axial clearance is existed between the two conductor discs. The rotation round blocks (6) can be in synchronization rotation manually or automatically on the magnetic force disc (10). The conductor ring and the permanent magnet are in corresponding arrangement, torsional force of eddy-current coupling realizes power transmission, angles of the rotatable rotation round blocks are changed, transmission torque is changed, and a purpose of changing load rotating speed is realized.
