    GCBASIC
    GCBASIC is an open-source BASIC compiler for 8 bit Microchip PIC, Atmel AVR legacy, AVRDx and LGT microcontrollers. See https://ko-fi.com/post/The-Story-of-GCBASIC-Making-Microcontroller-Progr-D1D319SJ72 for story of GCBASIC. This is a continuous release project. The latest release is always available. This will give you the most complete development toolchain to create and program 8-bit PIC, AVR and LGT microcontrollers. We have added new capabilities that make GCBASIC the easiest tool set available - supporting over 1400 microcontrollers with tools to make this fun and simple. Please see the download section for your options. We have two IDEs, we have just the compiler and we have a minimal install - it is your choice. Please see the homepage here: https://gcbasic.com

    GHDL

    GHDL

    VHDL 2008/93/87 simulator

    This directory contains the sources of GHDL, the open-source analyzer, compiler, simulator and (experimental) synthesizer for VHDL, a Hardware Description Language (HDL). GHDL is not an interpreter: it allows you to analyze and elaborate sources for generating machine code from your design. Native program execution is the only way for high-speed simulation. Full support for the 1987, 1993, 2002 versions of the IEEE 1076 VHDL standard, and partial for the 2008 and 2019 revisions. By using a code generator (LLVM, GCC or, x86_64/i386 only, a built-in one), it is much faster than any interpreted simulator. It can handle very large designs, such as leon3/grlib. GHDL runs on GNU/Linux, Windows and macOS; on x86, x86_64, armv6/armv7/aarch32, aarch64 and ppc64. You can freely download nightly assets, use OCI images (aka Docker/Podman containers), or try building it on your own machine.

    GroIMP

    GroIMP

    Growth-grammar related Interactive Modelling Platform

    Important: Groimp migrates to Gitlab. You can find the latest code at "https://gitlab.com/grogra/groimp/". The version on Sourceforge will not be updated anymore. The modelling platform GroIMP is designed as an integrated platform which incorporates modelling, visualisation and interaction. It exhibits several features which makes itself suitable for the field of biological or ALife modelling: The “modelling backbone” consists in the language XL. It is fully integrated, e.g., the user can interactively select the rules to be applied. GroIMP provides classes that can be used in modelling: Turtle commands, further geometrical classes like bicubic surfaces, the class Cell which has been used in the Game Of Life implementation, and so on. The outcome of a model is visualised within GroIMP. In the visual representation of the model output, users can i
