I think you want to see the wave forms. Push the button that looks like a man running. Then hold the cursor over the wire "output". Click.
I think you need to set up V1 and V2.
OK thank you very much for helping. Now I try to make some circuit
Great tip- I tried setting both Vhigh and clock V to 5 and to 1 volt. Both worked. Thank youRight click on the flip flop to open the component attribute editor.
In there, goto SpiceLine and enter the following string
Vhigh 5 Trise 1u Tfall 1u
This will set the flip flop to 5v.. The rise/fall time to 1 microsecond.
There are more parameters you can add but this is the bare minimum you would need to get things running =]
