Transaction based design: another buzzword or the solution to a design problem?

Complex systems on chip (SoCs) present challenges in the design and verification process that cannot be adequately addressed by traditional methodologies based on register transfer descriptions. Some of the aspects are efficient design exploration based on component reuse, getting closure on the architecture, as well as early development, integration and verification of embedded software. In search for responses to these challenges, Transaction level modeling (TLM) has got quite some attention in the area of SoC design. This panel attempts to do a reality check on TLM from an engineering point of view. Questions to discuss are: Is the Transaction Level (TL) really useful for the design and/or for the verification of SoCs? How can TL speed up the design process and lowering the risk of design failures? What are the implications on tools, languages, and Intellectual Property (IP) used in the design/verification process? The panelists will share their thoughts on transaction based design and verification, and will discuss benefits and issues based on their experiences of applying transaction level methodologies.
