Shared Library of circuit sim files?

[mikeinfodoc]

I have and use LTSPice and NI's Multisim circuit software simulators.

Does anyone know of a website where there are downloadable prebuilt circuit sim files (for either of the products above)?

Sort of like a GitHub, but containing a library of prebuilt, commonly-used circuit sim's  (such as some simple/standard/common circuits such as buck/boost/schmitt/etc)

For example, somewhere in which I could download sample circuits which others have built and tested.

Currently, I am hoping to find some schmitt comparator circuit sims, as my feeble attempts to get desired results from my created sim files are not working as I desire.

Most spice vendors have some standard examples in their tool. As well as semiconductor
vendors with their own tools and examples. Both online tools and offline. No central
database I am aware of covering the industry.

For example ON Semi has downloadable tools and examples for a number
of parts, including various regulator architectures. Same for TI,(Tina TI)....

I found some useful open circuits online here:

They also let you run/simulate the circuit and show scope results.
