Automatic Transactor Generation in Tlm by Exploiting Efsms *

One of the main critical tasks in a design flow based on Transaction Level Modeling (TLM) is the implementation of transactors. In fact, even if transactors represent the key objects to allow TLM-RTL mixed simulation, testbench and assertion reuse, their implementation is still manual, tedious and errorprone. The paper firstly classifies two scenarios as starting points to generate transactors and then, for each scenario, a suitable methodology is presented to automate the generation process exploiting the Extended Finite State Machine (EFSM) model.
