Dear Navaneethan

Please attach the circuit diagram and used CNTFET model for H-spice, so I give comprehensive help.

Best regards

Dear Majid

                           Thanks for your kind reply.

 i am using stanford 32nm model for CNTFET.

i want to design an circuit with delay as picosecond and power as nanowaatt ranges.

Here with i ll attach the circuit diagrams and code for your reference.

Propogation delay and avgpower calculation only makes me in trouble.
