TECHNICAL ARTICLES

General

ISTO5001 Paper
This article (APB179) looks at the NEXUS IEEE-ISTO 5001 standard for on-chip debug.

External-Trigger, User-Trace and General-Purpose-I/O on Ashling's Vitra, Genia and Opella 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.

License Transfer
This article (APB170) outlines how to transfer a License for Ashling's PathFinder Debugger from one PC to another, one location to another, or one directory to another.

Third-party Debuggers compatible with Ashling's Vitra, Genia and Opella Emulators
Ashling's Vitra, Genia and Opella Emulators support real-time debugging on many widely-used RISC embedded-processor architectures. The preferred Source-Debugger software for most of these architectures is Ashling's PathFinder Debugger, because of its support for Real-Time Trace and Triggering on the Vitra Emulator, the wide range of Compilers that it supports, and the ease of installing, learning and using the PathFinder software. In many cases, Ashling also supplies a Software-Driver (generally in the form of a Windows DLL) that provides an open Application Programming Interface (API) to allow third-party programs (such as debuggers or user-written test harnesses) to communicate with the Ashling Emulators as outlined in this article (APB175).

Reconfiguring Ashling's Vitra and Genia Emulators for a different target architecture
Ashling's Vitra and Genia Emulators support real-time debugging on many widely-used RISC embedded-processor architectures. Reconfiguring from one architecture to another is very easy as outlined in this article (APB178).
