The authors present a technique to synchronize between PSL (property specification language) checkers and SystemC IPs at the highest abstraction level of the ST Microelectronics system flow: transaction level modeling (TLM). A new assertion-based verification approach is proposed. It consists of a runtime simulation of the system-on-chip (SoC) under verification with PSL checkers. In this approach, the PSL checkers that represent the system specification are converted into C++ and therefore into a SystemC-TLM modules, which refer to us as TLM checkers. However, when integrating TLM checkers with SystemC models of SoC, the traditional clock-based synchronization at register transfer level and lower could not be applied. In fact, at the TLM abstraction level, the modeling rules forbid the use of a hardware clock. A new synchronization policy should be then proposed, hence the aim of this paper
