Patent US 9,552,448

A method of transmitting data is disclosed. At least one system block of a system-on-chip (SoC) is modeled at an untimed functional level in first and second untimed functional models. First and second transaction level (TL) models of the at least one system block system block are modeled at a transaction level (TL) using the first and second untimed functional models, respectively. First and second cycle accurate (CA) models are modeled at a cycle accurate (CA) level using the first and second TL models, respectively. Data is transmitted from the first untimed functional model to the first CA model, from the first CA model to the second CA model via a CA bus, and from the second CA model to the second untimed functional model.
