Abstract
An integrated circuit may include user storage circuits and scan storage circuits. The scan storage circuits may store data from the user storage circuits and provide the data to a user interface during a read-back operation. The user storage circuits may store data from the scan storage circuits, which the scan storage circuits may have received from the user interface during a write-back operation. The scan storage circuits may be arranged in a scan chain and controlled by a local control circuit. The integrated circuit may include multiple local control circuits that each control a sector of the integrated circuit. The local control circuits may communicate with a global control circuit over a communication network, and the global control circuit may communicate with the user interface.
