Abstract: A trigger function display system and methodology for trigger definition development in a signal measurement system having a graphical user interface. The system displays a plurality of graphically selectable icons and an associated protocol profile window. The protocol profile window includes at least a protocol descriptor field and a protocol editors field. The user inputs data into the protocol editors field which causes the system to automatically construct a bit sequence utilizing a plurality of event definitions stored in memory. The event definitions are two bit blocks resulting from the parsing of protocol definition text files. The bit sequence is used to then construct a series of trigger primitives. An optimizing routine is used to consolidate consecutive multiple occurrences of identical bit patterns in the bit sequence into single trigger primitives.

Abstract: A method for retrieving selected, predetermined data values using a logic analyzer and data visibility macros. The predetermined data values result from data operations that occur internally to the target processor. The data visibility macros send the data values via the external bus so that the logic analyzer may retrieve them for display. The data visibility macro is essentially a code marker, the difference being that a data visibility macro is used by the logic analyzer to retrieve data value information. The present method comprises the steps of inserting a data visibility macro into software code that is resident in the processor, compiling the code, writing the selected data values to an external bus, and using the logic analyzer to retrieve and display the data values.
