Abstract:
Disclosed are techniques that can be used in a semiconductor chip to determine performance such as timing performance. Among other features, supply voltages and clock rates may be adjusted to accommodate the operating temperature and to compensate for the processing variations that occurred when that chip was produced, or may occur as the chip is used. The techniques include determining a series of variables that affect performance, determining the sensitivity of timing paths in the circuit to each variable, duplicating the most sensitive paths. A novel sensor circuit is produced that includes the sensitive paths, which can be used to determine when the chip is performing as required and when it is not, and adjusting one or more supply voltages and/or clock rates in a static or real time manner when the circuit is not performing as required.

Claim (Index 23):
A system for sensing performance of a semiconductor circuit, the system comprising:\n a performance sensor, comprising:\n a system clock input configured to receive a clock signal, \n a plurality of timing paths, wherein each timing path has an input and an output, each timing path is representative of a path in a semiconductor circuit and each timing path is associated with a particular parameter dependent on one or more of a temperature or a semiconductor process, \n a logic circuit having a plurality of inputs and at least one output, wherein the output from each of the timing paths is coupled to an input of the logic circuit, \n a trigger circuit having a clock input obtained from the output of the logic circuit, and \n a timing circuit having an input that is related to the output of the logic circuit and having an output that changes from a first level to a second level upon a determination that a timing requirement for at least one of the timing paths is not met; and \n a voltage regulator circuit coupled to the output of the performance sensor, the voltage regulator configured to receive a supply voltage and to adjust a value of the supply voltage provided to the semiconductor circuit based on the output of the performance sensor.
