Transaction Level Modeling (TLM) improves the simulation performance by raising the abstraction level. In the TLM 2.0 standard based on OSCI SystemC, a single transaction can transfer a large data block. Due to such high abstraction, a great amount of information becomes invisible and thus timing accuracy can be degraded heavily. The authors present a methodology to accurately time such block transactions and achieve high simulation performance at the same time. First, before abstraction, a profiling process is performed on an Instruction Set Simulator (ISS).
