gpsim is a full system simulator for Microchip PIC microcontrollers originally written by Scotte Dattalo.[1] 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 ALL of the 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.[2]

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