Abstract

It is often the case that in the development of a system-on-a-chip (SoC) design, a family of SystemC transaction level models (TLM) is created. TLMs in the same family often share common functionalities but differ in their timing, implementation, configuration and performance in various SoC developing phases. In most cases, all the TLMs in a family must be verified for the follow-up design activities. In our previous work, we proposed to call such family TLM product line (TPL), and proposed feature-oriented (FO) design methodology for efficient TPL development. However, developers can only verify TLM in a family one by one, which causes large portion of duplicated verification overhead. Therefore, in our proposed methodology, functional verification of TPL has become a bottleneck. In this paper, we proposed a novel TPL verification method for FO designs. In our method, for the given property, we can exponentially reduce the number of TLMs to be verified by identifying mute-feature-modules (MFM), which will avoid duplicated verification. The proposed method is presented in informal and formal way, and the correctness of it is proved. The theoretical analysis and experimental results on a real design show the correctness and efficiency of the proposed method.
