I do not know simulation. However your schematic is incorrect.
Q2 goes nowhere and all connections to it can be deleted.
There should only be one resistor in series with LED's. (Usually)
What is LED with no red inside it?
What are triangles with 2 dots?
LED's usually take something like 1.5 volt. (1.5 volt is from my memory and it may be higher) Three LED's in series require 4.5 volt. 4.5 volt is too high a voltage to use with 5 volt power supply.
If resistors are 5 ohm, that is too low a resistance to use with LED's, (Usually)
Is there a connection missing from bottom resistor?

ty for your response. Triangles are the inverters, i want to make the word TEA... but it does not let me do E without the convergence failed

 

[Carl Pugh]

I goggled voltage red LED. Voltage for red Led is something like 1.8 volt.
With 5 volt power supply, you cannot put more than 2 LED's in series. One LED would be better.
Inverters cannot connect to LED's without a resistor in series.
If all you want to do is spell the word TEA, why don't you do it with resistors and LED's? No computer or invertors required.
Convergence is failing because current is outside permissible range.
