Hey guys. So I finally finished designing my circuit with tons of help from people on the forums and have it working how I want. Now I want to replace the op amp/comparitor/flip flop parts I've been using in my simulation (which I just randomly chose) with the actual circuit components I will be using for my project just to double check that it will still work as expected. Models for the actual components weren't available in the standard multsim library, but I was able to download the .MOD files for the components from the National Semiconductor website. The files are sitting on my desktop, but for the life of me can't figure out how to import them into multsim (v. 10) so I can place them in my simulation. If anyone knows how to do this, it would be great! Thanks!
