Open Source Java Simulation Software for Linux

EduMIPS64 (aka edumips) is a cross-platform MIPS 64 ISA simulator. It can be used to run and debug MIPS programs that are written using the MIPS64 instruction set. It supports visual debugging and lets you see what instructions do in the pipeline.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

AmazonTP is a GUI and API for automatic generation of power quality events by invoking the popular ATP (Alternative Transient Program).

JCPUSim is a CPU (Central Processing Unit) simulator written in Java. It is intended to aid in teaching how the fetch-decode-execute cycle, CPU, registers, memory and assembly programming language work in a computer system.

JSim8086 is platform-independent Assembly Language Simulator of the Intel 8086 CPU. It was designed to be a learning tool (CAL) for first year Computing students who are learning Computer Systems Organisation and Assembly Programming.

It provides a graphical animated representation of a network simulation run (e.g. for ns-2). Further, common metrics are calculated and displayed. The tool is written in Java and supplies 2 frontends (applet and stand-alone application).

We introduce a completely visual representation based on typed Mind Maps to represent steps of calculation for a pure untyped lambda calculator, VLM.

Yet another COSI Clone is an assembly computer simulation.

jFAST is a simple finite automata (FA) graphical simulation utility; it is designed to feature simple mechanisms for creating, editing, and simulating FA. jFAST is ideal for use by students, instructors, and self-guided explorers alike.

msgnet is a library that implements a simulation framework with visualisation for message passing networks. This might be useful for teachers and students of distributed systems courses.
