Dieses Buch stellt eine umfassende Reihe von Techniken vor, die alle wichtigen Aspekte eines modernen Virtual Prototype (VP)-basierten Entwurfsablaufs verbessern. Die Autoren legen den Schwerpunkt auf automatisierte formale Verifikationsmethoden sowie auf fortgeschrittene, abdeckungsgeleitete Analyse- und Testtechniken, die auf SystemC-basierte VP und die zugehörige Software (SW) zugeschnitten sind. Die Abdeckung umfasst auch VP-Modellierungstechniken, die sowohl funktionale als auch nicht-funktionale Aspekte behandeln, und beschreibt zudem Korrespondenzanalysen zwischen der Hardware- und VP-Ebene, um die auf verschiedenen Abstraktionsebenen verfügbaren Informationen zu nutzen. Alle Ansätze werden ausführlich diskutiert und anhand mehrerer Experimente evaluiert, um ihre Effektivität bei der Verbesserung des VP-basierten Entwurfsablaufs zu demonstrieren. Darüber hinaus legt das Buch einen besonderen Schwerpunkt auf den modernen RISC-V ISA, mit mehreren Fallstudien, die sowohl Aspekteder Modellierung als auch der VP- und SW-Verifikation abdecken.

This book presents a comprehensive set of techniques that enhance all key aspects of a modern Virtual Prototype (VP)-based design flow. The authors emphasize automated formal verification methods, as well as advanced coverage-guided analysis and testing techniques, tailored for SystemC-based VPs and also the associated Software (SW). Coverage also includes VP modeling techniques that handle functional as well as non-functional aspects and also describes correspondence analyses between the Hardware- and VP-level to utilize information available at different levels of abstraction. All approaches are discussed in detail and are evaluated extensively, using several experiments to demonstrate their effectiveness in enhancing the VP-based design flow. Furthermore, the book puts a particular focus on the modern RISC-V ISA, with several case-studies covering modeling as well as VP and SW verification aspects.

In his master thesis, Vladimir Herdt presents a novel approach, called complete symbolic simulation, for a more efficient verification of much larger (non-terminating) SystemC programs. The approach combines symbolic simulation with stateful model checking and allows to verify safety properties in (cyclic) finite state spaces, by exhaustive exploration of all possible inputs and process schedulings. The state explosion problem is alleviated by integrating two complementary reduction techniques. Compared to existing approaches, the complete symbolic simulation works more efficiently, and therefore can provide correctness proofs for larger systems, which is one of the most challenging tasks, due to the ever increasing complexity.
