Optimizations for a simulator construction system supporting reusable components

ABSTRACT

Exploring a large portion of the microprocessor design space requires the rapid development of efficient simulators. While some systems support rapid model development through the structural composition of reusable concurrent components, the Liberty Simulation Environment (LSE) provides additional reuse-enhancing features. This paper evaluates the cost of these features and presents optimizations to reduce their impact. With these optimizations, an LSE model using reusable components outperforms a SystemC model using custom components by 6%.
