OPTIMIZING OPERATING RANGE OF AN ELECTRONIC CIRCUIT

摘要

According to a method herein, a portion of an electronic circuit is identified. The electronic circuit comprises logic circuitry. The portion of the electronic circuit is designed in at least two versions. Each of the at least two versions is evaluated using a plurality of operating conditions. The current operating conditions are determined. One version of the at least two versions is identified as a selected version based on the performance under the current operating conditions. The selected version has relatively optimal performance based on at least one of clock frequency, supply voltage, and power limit. The selected version is activated for use in the portion of the electronic circuit. The remaining versions of the at least two versions are deactivated.

1. A method, comprising:
identifying a portion of an electronic circuit; designing said portion of said electronic circuit in at least two versions; evaluating each of said at least two versions using a plurality of operating conditions; determining current operating conditions; identifying one version of said at least two versions as a selected version, said selected version having relatively optimal performance under said current operating conditions based on at least one of:
frequency requirements,power constraints, andprocess variation; activating said selected version for use in said portion of said electronic circuit; and repeating said identifying and said activating during usage of said electronic circuit to dynamically select different versions of said at least two versions as said selected version as said current operating conditions change.
