PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

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.

DLD V 2.0 Released Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display as well as CRT and digital Oscilloscope all provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems.

Statistics101 is an Integrated Development Environment (IDE) that uses a simple, powerful language called “Resampling Stats” to develop Monte Carlo programs to analyze and solve statistical problems. The original Resampling Stats language and computer program were developed by Dr. Julian Simon and Peter Bruce as a new way to teach Statistics to social science students. Of course, social science students aren't the only ones who can benefit. Anyone who wants to learn statistics will find that the resampling approach helps in understanding statistical concepts from the simplest to the most difficult. In addition, professionals who want to use resampling, bootstrapping, or Monte Carlo simulations will find Statistics101 helpful. More information at https://statistics101.sourceforge.io/

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.
