Hello,

Select the components from eSim librarires. The 555 timer should be from eSim_subckt

Thanks for the reply

I have added the components from eSim librarires only. I have choosen from eSim_subckt only as LM555n. But still the problem is persiting had not solved.

Going through above details there is no proper connections at C1. Check the value assigned
