Sumário:

This document contains the materials for the training action Techniques for Prototype Debugging and Validation, a part of the Design for Debug and Test module within workpackage 2 of the Leonardo INSIGHT II project. The objective of this training action consists of presenting the several aspects related to the prototype debug and validation phase. The several models used for simulation and the currently available debug tools for ASIC-based, microprocessor-based and hybrid ASIC / microprocessor -based prototype systems are first presented and the debugging techniques for each system type are then covered in detail. The necessity of following careful design for debug and test rules is stressed, leading the way to the following training actions: i) Design for Test Standards and Proposed Standards and ii) Design for Debug and Test Techniques.
