External-Trigger, User-Trace and General-Purpose-I/O on Ashling's Vitra and Genia Emulators
An optional Extended Trigger and Trace Probe Assembly (TPA-TRIG-TRACE) is available for Ashling's Vitra Emulator and Trace tools that adds the External-Trigger and User-Trace and General-Purpose-I/O capabilities as described in this article (APB161).

RTOS Monitoring and Debugging using Ashling's PathFinder Debugger
Embedded systems require the ability to multi-task (to perform several tasks at once). Some of these tasks may be required to respond and operate within a defined time-period. These requirements have lead to the development of Real-Time Operating Systems (RTOSs). An RTOS provides a framework (a Kernel) that allows an embedded microprocessor application to be built as a series of tasks. This article (APB166) looks at PathFinder's support for RTOS debug.

Remote Debugging
Remote debugging using the Ashling Genia or Vitra emulators. This article looks at how to setup and use your Ashling Emulator on an Ethernet network.
