history
Project history and usage
gpsim is a GPL/LGPL software simulator for Microchip PIC microcontrollers, with a command-line interface, GTK-based GUI, debugger-like controls, stimuli, modules, and support for many PIC families.
Project history
The gpsim site presents the project as part of the GNUPIC ecosystem: a full-featured simulator for Microchip PIC microcontrollers designed for accuracy, speed, and usefulness rather than visual polish.
Its design goal is whole-chip simulation, including the CPU core, I/O pins, and internal peripherals. The documentation emphasizes breakpoints, single-stepping, disassembly, memory inspection and changes, read/write breakpoints, trace buffers, stimuli, and modules.
The project used SourceForge for downloads, support trackers, mailing lists, and Subversion source browsing. Its site points users to released source tarballs, SVN checkout instructions, documentation generated from LyX, and a gpsim-devel mailing list.
Adoption history
gpsim was adopted in embedded and hobbyist PIC development because it offered a free software simulator with debugging concepts familiar from gdb-like workflows and in-circuit emulator usage.
The project also formed a small ecosystem around GNUPIC tooling. The official related-links section points to gpasm/gputils and other PIC tools, while the Windows section points to Borut Razem's gpsimWin32 port and installer.
SourceForge file feeds show continued packaged tarball releases across the 2010s and into the 2020s, which explains why the tool remains present in Unix package managers despite its older SourceForge-era development style.
How it is used
Users run `gpsim` to load PIC assembly/object artifacts, select a processor, inspect registers and memory, single-step or run code, set breakpoints, and connect simulated stimuli to pins.
The official documentation treats the command-line interface as central and also documents GUI windows such as register viewers, source browsers, breadboard views, scope windows, trace viewers, and module support.
The project is useful when a developer wants to test microcontroller code behavior without hardware or to debug peripheral interactions before moving to a device or in-circuit tool.
Why package nerds care
gpsim is a compact example of old-school embedded free software packaging: SourceForge hosting, generated HTML/PDF docs, a devel mailing list, GTK-era GUI pieces, and integration with assembler/debugging workflows.
For package maintainers, its value is in preserving a niche toolchain component for PIC work. It sits near gputils/gpasm rather than modern language-runtime stacks, and it keeps older embedded development workflows installable from standard package managers.
