    Hey guys,
    do you have a simulation using Simulink or Pscad(?) of a PWM modulator using a NE555 timer?

    Do you know if it works using Win 7?

    LTSpice IV can simulate using the 555 and yes it does work on Win 7 and Win 7 x64bit.

    LTSpice is a free download; google: "LTSpice download" and you will find it.

    There is a model of the NE555 in the Misc directory; however it is an "idealized" 555 timer instead of a component model to make the simulation run faster. You can't buy a 555 timer that good.

    I've posted LM555.zip, accessible from this post:
    http://forum.allaboutcircuits.com/showpost.php?p=277737&postcount=6
    with instructions on how to add the LM555 model to LTSpice.
