Abstract

A system and method for diagnosing a software system within a remote electronic device using a network is provided. A diagnostic controller controls diagnostics of the software system by instructing the remote electronic device to replace a selected software component of the software system with a diagnostic software component. The diagnostic software component has equivalent operational characteristics as the selected software component and includes trace logic that collects diagnostic data while operating with the software system. An analysis routine analyzes the diagnostic data and recommends a corrective measure for the software system.

Claims

1. A diagnostic system for diagnosing a software system operating within a remote electronic device where the software system includes one or more software components, the diagnostic system comprising:

a network communication interface that establishes communication to the remote electronic device;

a diagnostic controller for controlling diagnostics of the software system, the diagnostic controller instructing the remote electronic device to replace a selected software component of the software system with a diagnostic software component being transmitted to the remote device via the network communication interface;

the diagnostic software component having equivalent operational characteristics as the selected software component and including trace logic that collects diagnostic data while operating with the software system; and

an analysis routine that analyzes the diagnostic data and recommends a corrective measure for the software system.

2. The diagnostic system as set forth in claim 1 further including:

a database of diagnostic software components; and

search logic for identifying one of the diagnostic software components from the database that has equivalent operational characteristics as the selected software component.

3. The diagnostic system as set forth in claim 1 wherein the analysis routine includes search logic for matching one or more portions of the diagnostic data to one or more expected data stored in a database of expected data.

4. The diagnostic system as set forth in claim 3 wherein the diagnostic data includes input signals received by the diagnostic software component from the software system and output signals transmitted by the diagnostic software component during the operation of the electronic device.

5. The diagnostic system as set forth in claim 4 wherein the database of expected data includes, for a certain type of software component, a sequence of input signals and a corresponding sequence of output signals that are expected for a properly functioning software component.

6. The diagnostic system as set forth in claim 1 wherein the diagnostic controller is a computer programmed to control the diagnostics of the software system over a network.

7. The diagnostic system as set forth in claim 1 further including a database of corrective software components.

8. The diagnostic system as set forth in claim 1 wherein the diagnostic controller further includes logic for issuing reconfiguration instructions causing the electronic device to reconfigure characteristics of a hardware component therein to affect the operation of the software system.

9. An electronic device having one or more software components that operate within the electronic device, the electronic device comprising:

a diagnostic microcontroller, embedded within the electronic device, that controls a diagnostic test performed on a selected software component within the electronic device, the diagnostic microcontroller including logic for replacing the selected software component with a test software component that emulates the selected software component such that the electronic device operates with the test software component;

the test software component further including trace logic that collects operational data during the operation of the electronic device; and

a network communication interface that transmits the operational data to a remote diagnostic computer to analyze the operational data for errors.

10. The electronic device as set forth in claim 9 wherein one of the software components is an operating system, and the diagnostic controller further includes logic for issuing operating system instructions to cease execution of the selected software component before being replaced.

11. The electronic device as set forth in claim 9 wherein one of the software components is a device driver.

12. The electronic device as set forth in claim 9 wherein one of the software components is application program.

13. The electronic device as set forth in claim 9 further including reconfiguration control software to reconfigure the electronic device to operate with the test software component.

14. The electronic device as set forth in claim 13 wherein the reconfiguration control software includes logic for reconfiguring operational characteristics of a hardware component within the electronic device to affect the operation of the software components.

15. The electronic device as set forth in claim 9 further including a memory for receiving the test component software from the remote diagnostic computer.

16. A process of diagnosing a software system within a remote electronic device where the software system includes one or more software components, the process comprising the steps of:

transmitting a diagnostic software component to the remote electronic device that emulates operational characteristics of a software component within the software system;

instructing the electronic device to operate with the diagnostic software component in place of the software component;

collecting, with the diagnostic software component, operational data transmitted between the diagnostic software component and other components of the electric device; and

receiving and analyzing the operational data from the electronic device to diagnose defects in the software system.

17. The process of diagnosing as set forth in claim 16 further including identifying the diagnostic software component that corresponds to the software component from a database of diagnostic software components.

18. The process of diagnosing as set forth in claim 16 further including instructing the software system to install the diagnostic software component in place of the software component.

19. The process of diagnosing as set forth in claim 16 wherein the diagnostic software is transmitted from a diagnostic computer over a network to the remote electronic device.

20. The process of diagnosing as set forth in claim 16 wherein the software component is selected by isolating a possible defect in the software system based on observed behaviors of the electronic device.
