DLSys: A Toolkit for Design and Simulation of Computer System Architecture
John L. Donaldson, Richard Salter, Rebecca E. Punch · 2011
is a GUI-based digital logic simulator designed for use in Computer Organization and Architecture courses. Its key features are support for abstraction (allowing subcircuits to be abstracted as black boxes) and extensibility (allowing new circuit elements to be created as Java plug-ins). These features make DLSim 3 suitable for use at all levels of Computer Organization study. The purpose of this paper is to demonstrate the use of DLSim 3 at the system architecture level. We introduce DLSys, a collection of DLSim 3 circuits and plug-ins intended for use in the design and simulation of single- and multiple-CPU computer systems.
