Circuit Simulation Software

  1. Feb 20, 2013 #1
    Hi I am working on a project at the moment and I was wondering if there is any circuit simulator that includes the PIC 18F4550 microcontroller. I currently use Crocodile Technology and I have tried editing the code to get the chip to just appear (I don't need it to do anything just sit there so I can wire around it) but it just crashes. So I am wondering if there is any software out there that has the chip in it. Also I want it to appear as it does in the datasheet i.e all 40 pins instead of just the i/o pins

    Why would you put a chip in a simulator, if the chip is not going to do anything in the simulation?

    I don't understand what you mean by "wire around it"?

    Just so I can see what parts I need and how I would wire it. If it could simulate that would be brilliant but the bare minimal is to be able to be put into a circuit.

    Does your simulator have blank ICs that are just rectangles with numbered pins?

    It does but nowhere near the amount of pins on the PIC 18F4550

    If you are not actually going to simulate it, why not just use the schematic capture part of some PCB layout software ?
    I am pretty sure you can find symbols for PICs in say Eagle or DesignSpark (free versions available).

    Thanks f95toli DesignSpark works out, thanks for the help :)
