Path margin monitoring

A non-transitory computer-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• determining a plurality of threshold margins corresponding to a plurality of functional paths in an electronic circuit;
• storing the plurality of threshold margins corresponding to the plurality of functional paths in a memory;
• receiving a first trigger from a processing device;
• responsive to receiving the first trigger, capturing first path margin monitoring (PMM) data from a first section of the electronic circuit and second PMM data from a second section of the electronic circuit during in-field operation of the electronic circuit, wherein the first PMM data and the second PMM data each comprise at least one of the plurality of functional paths corresponding to the plurality of threshold margins in view of a previously determined threshold margin stored in the memory and corresponding to the at least one of the plurality functional paths for a respective section of the electronic circuit;
• and
• causing, by the processing device, a first feedback operation to be performed on the first section of the electronic circuit based on the first PMM data captured during the in-field operation of the electronic circuit, and causing a second feedback operation, different from the first feedback operation, to be performed on the second section of the electronic circuit based on the second PMM data captured during the in-field operation of the electronic circuit.

A system comprising:

• a memory;
• and
• a first processing device coupled to the memory, the first processing device to:
• determine a plurality of threshold margins corresponding to a plurality of functional paths in an electronic circuit;
• store the plurality of threshold margins corresponding to the plurality of functional paths in the memory;
• receive a first trigger from a second processing device;
• responsive to receiving the first trigger, capture path margin monitoring (PMM) data from a first section of the electronic circuit and second PMM data from a second section of the electronic circuit during in-field operation of the electronic circuit, wherein the first PMM data and the second PMM data each comprise at least one of the plurality of functional paths corresponding to the plurality of threshold margins in view of a previously determined threshold margin stored in the memory and corresponding to the at least one of the plurality functional paths for a respective section of the electronic circuit;
• and
• cause, by the first processing device, a first feedback operation to be performed on the first section of the electronic circuit based on the first PMM data captured during the in-field operation of the electronic circuit, and cause a second feedback operation, different from the first feedback operation, to be performed on the second section of the electronic circuit based on the second PMM data captured during the in-field operation of the electronic circuit.
