The rise of SoCs caused a paradigm shift on system design flow. The TLM methodology was created in the search for a new paradigm that could allow design representation at an intermediate level of abstraction between paper specification and RTL models. This chapter introduces the Transaction Level Modeling (TLM) design methodology. Its main goals ar...

In the Electronic System Level (ESL) environment, a key factor is the early integration of verification into the design flow. Higher levels of abstraction must not be appealing just for their fast simulation speeds, but also for their flexibility and capabilities when debug and analysis come into play. This creates a demand for new functionalities...

Post-partitioning verification has to deal with abstract data, implementation artifacts, and the order of events may not be preserved in the DUV due to the concurrency treatment in the golden model. Existing techniques are limited either by the use of greedy heuristics (jeopardizing verification guarantees) or by black-box approaches (impairing obs...

System-level and Platform-based design, along with Trans- action Level modeling (TLM) techniques and languages like SystemC, appeared as a response to the ever increasing com- plexity of electronics systems design, where complex SoCs composed of several modules integrated on the same chip have become very common. In this scenario, the exploration a...

Transactional memory (TM) is an emerging synchronization mechanism that aims to solve most of the difficulties inherent in lock-based approaches.
