“…Software reuse is promoted with an increase of abstraction from the underlying communication. Siegmund and Müller [2001] describe with SystemC SV an extension to SystemC and propose SoC modeling at three different levels of abstraction: physical description at RTL, a more abstract model for individual messages, and a most abstract model utilizing transactions. Brem and Müller [2003] describe how the CAN bus is modeled using SystemC SV .…”

The increasing complexity of embedded systems requires modeling at higher levels of abstraction. Transaction level modeling (TLM) has been proposed to abstract communication for high-speed system simulation and rapid design space exploration. Although being widely accepted for its high performance and efficiency, TLM often exhibits a significant loss in model accuracy.In this article, we systematically analyze and quantify the speed/accuracy trade-off in TLM. To this end, we provide a classification of TLM abstraction levels based on model granularity and define appropriate metrics and test setups to quantitatively measure and compare the performance and accuracy of such models.Addressing several classes of embedded communication protocols, we apply our analysis to three common bus architectures, the industry-standard AMBA advanced high-performance bus (AHB) as an on-chip parallel bus, the controller area network (CAN) as an off-chip serial bus, and the Motorola ColdFire Master Bus as an example for a custom embedded processor bus.Based on the analysis of these individual busses, we then generalize our results for a broader conclusion. The general TLM trade-off offers gains of up to four orders of magnitude in simulation speed, generally however, at the price of low accuracy. We conclude further that model granularity is the key to efficient TLM abstraction, and we identify conditions for accuracy of abstract models. As a result, this article provides general guidelines that allow the system designer to navigate the TLM trade-off effectively and choose the most suitable model for the given application with fast and accurate results.

Currently, since many SoCs include heterogeneous components such as CPUs, DSPs, ASICs, memories, buses, etc., system integration becomes a major step in the design flow. To enable this integration, we use a design approach called component based-design approach. In this approach, the validation of system integration takes most of design efforts. This paper presents an automatic method of SoCs design validation. Based on a generic simulation wrapper architecture, the presented method provides automatic generation of executable models throughout different stages of SoC design flow. A case study of validating a VDSL application shows the effectiveness of the method.

Accurate modeling of communication is a necessary part of system level design for real-time safety-critical applications. For efficient prediction of a system's performance, Transaction Level Modeling (TLM) is often used which increases the simulation speed by orders of magnitude. The speed advantage, however, comes at the cost of low accuracy.In this paper, we use a novel modeling technique, called Result Oriented Modeling (ROM), which yields 100% accuracy in timing, yet approaches the same speed as traditional TLM. ROM also abstracts away internal details of the communication but, in contrast to TLM, fully maintains accurate timing. ROM optimistically predicts the timing and retroactively takes corrective measures, if necessary.In this paper, we compare the ROM technique to TLM at different levels of abstraction, using a Controller Area Network (CAN) bus example. Our results show that ROM yields a simulation speedup close to the traditional TLM, yet exhibits the same timing accuracy as a bus functional model. Thus, for safety-critical real-time applications, ROM is a viable replacement for the inaccurate TLM.
