Abstract

An identification system for identifying and validating selected components of a communication system and methods for manufacturing and using same. The communication system includes a host system that is configured to couple with one or more target systems. When the host system is coupled with a selected target system, the communication system can enter an identification mode wherein the selected target system can provide identification data to the host system. The identification data includes information regarding at least one target system characteristic associated with the selected target system such that the host system can attempt to identify the selected target system based at least in part upon the target system characteristics. Once the selected target system has been identified, the communication system likewise can at least partially reconfigure the host system, as necessary, such that the host system can be compatible with the selected target system.

Claims (28)

1. An identification system for identifying a target system, comprising:

a biasing system for providing a predetermined signal state on a selected conductor of a communication cable assembly for coupling the target system with a hardware logic emulation system; and

a processing system for receiving said predetermined signal state via said selected conductor, wherein the processing system places the target system into an identification mode in response to said received predetermined signal state and wherein the target system while in the identification mode provides information regarding a target system characteristic including a system type of the target system to the hardware logic emulation system via the communication cable assembly, said processing system being remote from said biasing system,

wherein, once the hardware logic emulation system has identified the target system in response at least partially to the system type of the target system characteristic, the hardware logic emulation system places the target system out of the identification mode and into an operation mode,

wherein the target system communicates with the hardware logic emulation system in the operation mode to verify the functionality of a logic circuit design;

wherein said biasing system provides a predetermined signal state on each of a plurality of selected conductors of the communication cable assembly; and

wherein each of said predetermined signal states of said plurality of selected conductors provides a target system characteristic of varying levels.

2. The identification system of claim 1 , wherein said biasing system comprises a passive biasing system.

3. The identification system of claim 2 , wherein said biasing system includes a resistive element.

4. The identification system of claim 3 , wherein said resistive element comprises a resistor.

5. The identification system of claim 3 , wherein said resistive element comprises a transistor.

6. The identification system of claim 3 , wherein said resistive element is provided via an input/output block of a field-programmable gate array.

7. The identification system of claim 3 , wherein said resistive element is coupled with a reference source.

8. The identification system of claim 7 , wherein said reference source comprises a voltage reference source.

9. The identification system of claim 7 , wherein said reference source comprises a current reference source.

10. The identification system of claim 3 , wherein said resistive element is grounded.

11. The identification system of claim 1 , wherein the predetermined signal state of at least one of said plurality of selected conductors differs from another predetermined signal state of at least one other of said plurality of selected conductors.

12. The identification system of claim 1 , wherein the predetermined signal states of said plurality of selected conductors comprise hierarchical signal states.

13. The identification system of claim 1 , wherein said biasing system adjustably biases said selected conductor.

14. The identification system of claim 1 , wherein said biasing system couples with the communication cable assembly.

15. The identification system of claim 14 , wherein said biasing system removably couples with the communication cable assembly.

16. The identification system of claim 14 , wherein said biasing system indirectly couples with the communication cable assembly via the target system.

17. The identification system of claim 1 , wherein said processing system includes a database for identifying the target system.

18. The identification system of claim 1 , wherein said processing system includes a look-up table for identifying the target system.

19. The identification system of claim 1 , wherein said processing system couples with the communication cable assembly.

20. The identification system of claim 19 , wherein said processing system removably couples with the communication cable assembly.

21. The identification system of claim 19 , wherein said processing system indirectly couples with the communication cable assembly via the hardware logic emulation system.

22. The identification system of claim 1 , wherein said processing system reconfigures the hardware logic emulation system to be compatible with the target system.
