Abstract

A signal manager includes a signal monitor [102], a programmable logic device [108], a signal storer [116], and a signal router [118]. The signal monitor

is configured for monitoring at least one selected signal of a set of selected signals being captured at a programmable logic device [108]. The selected signal includes at least one signal internal to the programmable logic device [108] that is coupled with a server. The signal storer [116] is configured for storing the monitored set of selected signals. The signal router [118] is configured for routing a portion of the monitored set of selected signals to a selected output location local or remote in response to a routing instruction.

Claims

2. The non-transitory computer-readable storage medium of claim 1, wherein said method [200] further comprises instructions for:

receiving [208] a signal selection instruction [126]; and

commanding said programmable logic device [108] to capture said set of selected signals according to received signal selection instruction [126].

3. The non-transitory computer-readable storage medium of claim 2, wherein said commanding said programmable logic device [108] to measure a selected signal comprises:

utilizing [212] a common command protocol while communicating with said programmable logic device [108].

4. The non-transitory computer-readable storage medium of claim 2, wherein said monitoring at least one selected signal [104] of a set of selected signals [106] being captured at a programmable logic device [108] comprises:

monitoring [214] at least one selected signal of a set of selected signals being captured at said programmable logic device [108] based on a tugger event occurring.

5. The non-transitory computer-readable storage medium of claim 4, wherein said monitoring at least one selected signal of a set of selected signals being captured at said programmable logic device [108] based on a trigger event occurring comprises:

monitoring at least one selected signal [104] of a set of selected signals [106] being captured at said programmable logic device [108] based on an occurrence of a trigger selected from a group of huggers consisting of a rising edge, a falling edge, a change in rate or a threshold value being exceeded.

6. The non-transitory computer-readable storage medium of claim 4, wherein said method [200] further comprises instructions for resetting said trigger event automatically according to a predetermined trigger event instruction [132].

7. The non-transitory computer-readable storage medium of claim 6, wherein said method [132] further comprises instructions for:

receiving [220] a reset instruction [138]; and

resetting said trigger event in response to said receiving a reset instruction [138].

8. A non-transitory computer-readable storage medium of claim 1, wherein said monitoring at least one selected signal [104] of a set of selected signals [106] being captured at a programmable logic device [108]comprises:

monitoring in real-time at least one selected signal [104] of a set of selected signals [104] being captured at a programmable logic device [108] to achieve a monitored set of selected signals [110], said at least one selected signal [104] comprising at least one signal internal to said programmable logic device [108], said programmable logic device [108] being coupled with said server [114]. Wherein said server [114] comprises a self-contained server;

storing [204] said monitored set of selected signals [110]; and

in response to a routing instruction [122], routing [228] a portion of said monitored set of selected signals [110] to a selected output location [120] specified by said routing instruction [122].

9. The non-transitory computer-readable storage medium of claim 1, wherein said monitoring at least one selected signal [104] of a set of selected signals [106] being captured at a programmable logic device [108] to achieve a monitored set of selected signals [110] comprises:
