System C TLM 2.0
Transaction-Level Modeling 2.0 (TLM-2.0) is a modeling methodology defined in IEEE 1666-2023. Instead of communicating through individual signals at every clock cycle, modules exchange complete transactions (read/write requests) using C++ function calls. This raises the abstraction level, dramatically increasing simulation speed and enabling early software development before RTL is available. 1. Introduce TLM-2.0 replaces pin-level signal connections with high-level function calls carrying a tlm_generic_payload transaction object. An initiator (e.g., a CPU model) calls transport functions on a target (e.g., a memory) through typed sockets and a bus/router. ...
