    XSCHEM

    XSCHEM

    Schematic circuit editor for VLSI and Mixed mode circuit simulation.

    Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this...

    42

    Simulation for spacecraft attitude control system analysis and design

    42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics. Its primary purpose is to support design and validation of attitude control systems, from concept studies through integration and test. 42 accurately models multi-body spacecraft attitude dynamics (with rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, modelling environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft concurrently, facilitating studies of rendezvous, proximity operations, and precision formation flying. ...

    Arduino Primary Avionics Module  (A-PAM)

    Arduino Primary Avionics Module (A-PAM)

    A foundational avionics system for model rockets

    ...These larger rockets also use larger propellants, typically in the High Power Rocketry (HPR) range of “H” and above impulse level. Not only do these motors require you to be certified in HPR, the motors themselves tend to be rather expensive. My goal was to develop a system that could be used by high school students. It would involve proven rocket designs that could be flown on school yards. That meant it needed to be small, fitting everything into a body tube with a diameter no more than 42mm. This would allow it to use “D” or “E” motors. It would need to be flexible. I wanted the design to be a starting point to allow them to conduct real science and it had to be inexpensive.
