gpsim for Mac

gpsim is a simulator for PIC microcontrollers, primarily used to run and debug programs written for these chips on a computer. For those learning embedded development or needing to verify the logic of PIC programs, it provides an environment where runtime behavior can be observed without repeatedly flashing the chip. As a command-line tool, it is better suited to developers who are comfortable working in a terminal and want to integrate simulation into scripts or automated workflows. The software follows the GPL license and is an open-source tool, with the official website providing basic project information and access details. If you are working with PIC series microcontrollers and looking for a lightweight simulation environment to support development or teaching, gpsim is worth looking into.
