Two-level rate-controlled sensor arrays to monitor logic paths through an integrated circuit

A method comprising:

• generating one or more first level indications of a condition of an integrated circuit in a first sensor array formed in an integrated circuit, sensors of the first sensor array having paths through the integrated circuit;
• actuating a second sensor array in response to the one or more first level indications falling below a threshold, sensors of the second sensor array having paths through the integrated circuit, and being more numerous than sensors of the first sensor array;
• and
• generating one or more second level indications of a condition of the integrated circuit in the second sensor array.
