    HP41CX

    HP41CX

    HP-41cx Emulator

    An Qt based HP-41cx Emulator first based on Eric's NSIM-0.61 Project. Ported to C++ and extended by an graphical Qt-based User-interface. Since Oct.2014 I developed my own NUT-Core implementation which is quite different from Eric's one. I called it NewT in fact of the existing NewT NUT Hardware revival.

    simutron

    simutron

    AVR simulator IDE

    Electronic circuit simulator. Simple environment to run and debug firmware for AVR 8-bit microprocessors. Able to run arduino firmware. Internally this program uses the open source Simavr AVR Processor Simulator (https://github.com/buserror/simavr) and wraps all its functions in a GUI shell. Setups for firmware debugging scenarios can be created dynamically. Able to run 16MHz MCU with decent set of external parts in real time. In particular this can be used for development of CNC firmware in conjuction with its CAM frontend without access to the real hardware. For Linux and Windows systems. Please visit wiki pages (https://sourceforge.net/p/simutron/wiki/Home/) for instructions

    The FMI++ Library

    The FMI++ Library

    A High-level Utility Package for FMI-based Software Development

    The Functional Mock-up Interface (FMI) specification intentionally provides only the most essential and fundamental functionalities in the form of a C interface. On the one hand, this increases flexibility in use and portability to virtually any platform. On the other hand, such a low-level approach implies several prerequisites a simulation tool has to fulfill in order to be able to utilize such an FMI component. The FMI++ library addresses this problem for models and tools with interfaces according to the FMI specification by providing high-level functionalities, which ease the handling and manipulation of such models and tools. Furthermore, the FMI++ library provides utilities to implement FMI-compliant interfaces for a large class of simulation tools. The FMI++ library intends to bridge the gap between the basic FMI specifications and the typical requirements of simulation tools. It is distributed using a BSD-like license.

    ACADO Toolkit

    ACADO Toolkit

    Toolkit for Automatic Control and Dynamic Optimization

    ACADO Toolkit is a software environment and algorithm collection for automatic control and dynamic optimization. It provides a general framework for using a great variety of algorithms for direct optimal control, including model predictive control, state and parameter estimation and robust optimization. ACADO Toolkit is implemented as self-contained C++ code and comes along with user-friendly MATLAB interface. The object-oriented design allows for convenient coupling of existing optimization packages and for extending it with user-written optimization routines.

    AirTSP

    Simulated Airline Travel Solution Provider Library

    AirTSP is also named AirTSP (TSP standing for Travel Service Provider). That project aims at providing a clean API and a simple implementation, as a C++ library, of an Airline Schedule Management System. It is intended to be used in simulated environments only: it is not designed to work in the real-world of Airline IT operations. AirTSP/AirTSP makes an extensive use of existing open-source libraries for increased functionality, speed and accuracy. In particular the Boost (C++ Standard Extensions: http://www.boost.org) library is used. AirTSP/AirTSP is the one of the components of the Travel Market Simulator (http://www.travel-market-simulator). However, it may be used in a stand-alone mode.
