Abstract: Integrated circuits may include embedded logic analyzer circuitry that monitors and stores data received from logic circuitry. The logic analyzer circuitry may include storage circuitry and logic analyzer control circuitry that controls the storage circuitry. The control circuitry may include trigger condition circuitry that compares the data to a trigger condition. When the data satisfies the trigger condition, the storage circuitry may stop storing the data and stored data may be conveyed to fault detection circuitry for debugging the design of the logic circuitry. The integrated circuit may include programmable memory elements that can be loaded with configuration data. The logic analyzer circuitry may include partial-reconfiguration control circuitry that reconfigures the control circuitry without reconfiguring other portions of the integrated circuit. The partial-reconfiguration control circuitry may, for example, update the trigger condition by reconfiguring the control circuitry while the rest of the integrated circuit continues to operate normally.
