The present invention logs events which occur in the target software, and stores these in a buffer for periodic uploading to a host computer. Such events include the context switching of particular software tasks, and task status at such context switch times, along with events triggering such a context switch, or other events. The host computer reconstructs the real-time status of the target software from the limited event data uploaded to it. The status information is then displayed in a user-friendly manner. This provides the ability to perform a logic analyzer function on real-time software. A display having multiple rows, with one for each task or interrupt level, is provided. Along a time line, an indicator shows the status of each program, with icons indicating events and any change in status.
