Sir ,
I am not able to simulate the Dee Dah siren circuit using NE555 Ic. I think the issue is regarding the Spice model of 555 . Can any one suggest the procedure for downloading the spice model and integrate with the simulator?

I’ve collected some links to getting started with simulation in KiCad. I think that it also has a working example with an NE555 somewhere in there. And at least it also has links to other resources such as libraries.
If I am not mistaken, I think that the (more or less) complete internal schematic for the 555 chip is included in some datasheets.
The 555 is an old and rudimentary IC. I think you could reasonably copy the schematic from the datasheet into the simulator and work it that way.
