Thank you sir for responding. I have pasted the link above
Dear Abhinav,
The netlist is erroneous there are a lot of question marks present in the netlist indicating wrong/no connection. Also the units "ohms" need not be written after the Resistor values. Please recheck these things.
Please see the Spoken Tutorials videos to know how to create circuits in eSim:

Please feel free to ask if any queries.
Thanks & Regards,
Sumanto Kar
