System and method for designing digital circuitry with an activity sensor

摘要

The system (10) has a simulator (12) for simulating a digital circuit based on a file (14) containing a functional description. An output simulator (28) estimates a power consumption profile file from the circuit when executing a test bench file (26) supplied to the simulator. An event counter (34') counts the detected events by using control signals. A processor (40) and computer program select a portion of counters by iteratively optimizing a model calculating output variable e.g. temperature, by using output data from the counters and register the portion of event counters and the model. Independent claims are also included for the following: (1) a method for designing a digital circuitry (2) a computer program downloaded from a communication network and/or saved on a computer-readable medium and/or executed by a processor, comprising instructions to perform a method for designing a digital circuitry.
