DLSim, a GUI-based digital logic simulation program developed by Richard Salter at Oberlin Colleg... more DLSim, a GUI-based digital logic simulation program developed by Richard Salter at Oberlin College, has been used for class demonstrations and homework exercises in the Computer Organization course at Oberlin for over ten years. Until recently its use has been limited to the component of the course dealing with low-level logic design using gates and flipflops. A new version, DLSim 3, extends those capabilities through the use of Java plug-ins, making it possible to use the software for digital design at higher levels of abstraction. With DLSim 3, we are able to present the many levels of circuit design in a single environment, from low level combinational and sequential circuits through models of complete CPUs. The purpose of this paper is to give an introduction to DLSim 3 and to describe how we have used it in the classroom, focusing particularly on CPU design.

What distinguishes DLSim from other digital logic simulators is its robust plug-in system. Working with the DLSim plug-in system this summer presented us with an opportunity to explore progressively more complicated digital logic circuits in a virtual environment. We set out to implement a set of circuits that would test the capabilities and limits of the DLSim virtual logic simulating environment through the powerful abstraction tool provided by the plug-in system. Some of these circuits played a part in enhancing and testing the simplified MIPS processor, MicroMIPS, developed primarily by our mentor John Donaldson. Another was a user-programmable circuit designed for the implementation of boolean functions. The versatility of the DLSim plug-in system allowed us a high degree of creativity with our circuit designs. Through hands-on experience with DLSim we were able to better understand larger scale computer organization.
