MPLAB-SIM Simulator Software
The software simulator is a no-cost tool with which to evaluate Microchip’s products and designs.
The use of the simulator greatly helps debug software, particularly algorithms. Depending on the
complexity of a design project a time/cost benefit should be looked at comparing the simulator
with an emulator.
For projects that have multiple engineers in the development, the simulator in conjunction with
an emulator can keep costs down and will allow speedy debug of the tough problems.
MPLAB-SIM Simulator simulates the PICmicro series microcontrollers on an instruction level. On
any given instruction, the user may examine or modify any of the data areas or provide external
stimulus to any of the pins. The input/output radix can be set by the user and the execution can
be performed in; single step, execute until break, or in a trace mode.
MPLAB-SIM supports symbolic debugging using MPLAB-C, and MPASM. The Software Simula-
tor offers the low cost flexibility to develop and debug code outside of the laboratory environment
making it an excellent multi-project software development tool.
