Diagnosis for mixed signal device for use in a distributed system
First Claim
Patent Images
1. A device comprising:
- at least one analog module at an integrated circuit;
a diagnosis controller of the integrated circuit coupled to the at least one analog module, said diagnosis controller to generate operational status information of the at least one analog module based on an operational status of the least one analog module;
a comparison circuit of the integrated circuit operable to compare operational status information received from another diagnosis controller of a different integrated circuit about another module at the different integrated circuit against expected pre-calculated operational status information of the other module; and
a communication module coupled to the diagnosis controller to receive the operational status information from the other diagnosis controller and to transmit the operational status information of the at least one analog module to the different integrated circuit for comparison.

18. A method comprising:
-
determining operational status information of an analog module at an integrated circuit by using a diagnosis controller at the integrated circuit; sending the determined operational status information to a different integrated circuit for comparison with pre-calculated expected operational status information for the analog module; and comparing by a comparison circuit of the integrated circuit operational status information received from the different integrated circuit against expected pre-calculated operational status information for another module at the different integrated circuit.

19. A device comprising:
-
a plurality of analog modules at an integrated circuit; and a diagnosis controller at the integrated circuit coupled to the analog modules, the diagnosis controller to schedule requests for operational status from the analog modules, to receive operational status from the analog modules, to generate operational status information based upon the received operational status, the operational status information to be transmitted to at least one master controller, to receive commands about receiving and transmitting operational status from the master controller, and to carry out control commands received from the at least one master controller. - View Dependent Claims (20)
