Astable multivibrator

Cant fritzing Simulate blinking LEDs with an astable multivibrator or did i wire something wrong?

Currently, in version 1.0.2, it cannot simulate transitory analysis, only the operating point (DC).
However, I’m working on adding transitory analysis capabilities and then it would be possible. The code is online in the repository (check the pull requests) and you can try it if you compile Fritzing (which is not easy if you are not a developer ). We aim to include this branch in the next release.
