DEBUG STATE MACHINE CROSS TRIGGERING
First Claim
1. A method for performing debug operations in an electronic system that includes a plurality of electronic modules and a plurality of debug circuits, each debug circuit being integrated with a corresponding one of the plurality of electronic modules, the method comprising:
- each of the plurality of debug circuits producing a first cross trigger signal on a communications interface between the plurality of debug circuits, wherein the first cross trigger signal indicates that a triggering event has not occurred;
each of the plurality of debug circuits determining whether the triggering event has occurred; and
in response to determining that the triggering event has occurred, each of the plurality of debug circuits producing a second cross trigger signal on the communications interface, which indicates that the triggering event has occurred.

Abstract
In an electronic system that includes a plurality of electronic modules and a plurality of debug circuits, each of which is integrated with one of the plurality of electronic modules, a method for performing debug operations is performed by the plurality of debug circuits. The method includes each of the plurality of debug circuits producing a first cross trigger signal on a communications interface between the plurality of debug circuits, where the first cross trigger signal indicates that a triggering event has not occurred. The method further includes each of the plurality of debug circuits determining whether the triggering event has occurred, and in response to determining that the triggering event has occurred, each of the plurality of debug circuits producing a second cross trigger signal on the communications interface, which indicates that the triggering event has occurred.

16. An electronic system comprising:
-
a first electronic module; a second electronic module; a first debug circuit integrated with the first electronic module, wherein the first debug circuit is configured to produce a first cross trigger signal on a communications interface between the first debug circuit and a second debug circuit, wherein the first cross trigger signal indicates that a triggering event has not occurred, and wherein the first debug circuit is further configured to determine whether the triggering event has occurred, and in response to determining that the triggering event has occurred, to produce a second cross trigger signal on the communications interface, which indicates that the triggering event has occurred; and the second debug circuit integrated with the second electronic module, wherein the second debug circuit is configured to produce the first cross trigger signal on the communications interface, wherein the first cross trigger signal indicates that the triggering event has not occurred, to determine whether the triggering event has occurred, and in response to determining that the triggering event has occurred, to produce the second cross trigger signal on the communications interface, which indicates that the triggering event has occurred. - View Dependent Claims (17, 18, 19, 20)
