tina

I am a student working on an assignment for a monostable multivibrator circuit that runs for 3 seconds. This picture is given, but without values. When we use TINA, it doesn't run, so we need to figure out what the values are so we can build it in real life. We have 4 days left until submission.

Hello. I'm trying to simulate a twin T Oscillator using TINA. For some reason I can't succeed to create oscillation.Any thoughts?
