Interaction of Co-Design and Co-Simulation, based on Multi-Block-Systems

摘要

While simulation of any VLSI system like actual processors is quite complicated and time-consuming but solvable by different levels of simulation, the influence of software to the complete system behaviour remains hard to model. Especially responsive systems - the name for embedded systems with hard real-time constraints - are difficult to simulate by unplanable events from outside. This paper presents a simulation method as well as hardware architecture to handle such systems with more precision and confidence in the forecasts. This methodology is based on (virtual and real) multiblock machines and the introduction of threads associated with timing behaviour (so-called timethreads) for the operating system.
