Non-intrusive monitoring and control of integrated circuits

摘要

An application-specific integrated circuit (ASIC) is provided. The ASIC includes a group of non-configurable circuits customized for performing operations for a particular use. The ASIC also includes a set of reconfigurable circuits for configurably performing a set of operations based on configuration data. The ASIC also includes a configuration and monitoring network that receives a set of signals from the non-configurable circuits of the ASIC. The configuration and monitoring network also receives incremental sets of configuration data while the ASIC is performing operations of the user design. Each incremental set of data is used for reconfiguring the configuration and monitoring network (i) to monitor one or more signals in the set of signals and (ii) to take a set of actions when values of the monitored signals satisfy a condition.

主权项

1. A method of monitoring operations of an integrated circuit (IC), the IC comprising a set of configurable circuits for configurably performing a set of operations based on configuration data, the method comprising:
loading a first set of configuration data into the IC to configure a plurality of configurable circuits in the set of configurable circuits to perform operations of a user design; receiving a definition of (i) an event based on values of a set of signals in the user design and (ii) a set of corresponding actions to take when the event occurs; generating an incremental second set of configuration data based on the definition of the event and the set of corresponding actions; and while the IC is performing the operations of the user design, loading the incremental second set of configuration data into the IC to monitor for the event and to take the set of actions when the event occurs.
