gpsim is a full system simulator for Microchip PIC microcontrollers originally written by Scotte Dattalo.{{cite web|url=http://www.gnupic.dds.nl/simulators.html|title=Simulators|work=GNU Pic "Free Microcontroller Software Tools"|publisher=GNU PIC|accessdate=2012-09-25}}

It is distributed under the GNU General Public License.

gpsim has been designed for accuracy including the entire PIC - from the core to the I/O pins and including the functions of all internal peripherals. This makes it possible to create stimuli and tie them to the I/O pins and test the PIC the same way you would in the real world.{{Cite web|url=http://gpsim.sourceforge.net/gpsim.html|title=gpsim|website=gpsim.sourceforge.net|access-date=2019-09-05}}

The software can run natively in Windows using gpsimWin32, a port to Windows created by Borut Ražem.
