I am using RC model to test delay in this circuit.

However the RC model attenuates the signal rather delaying it from volts to milivolts.. clik 2 c d simulation... its nt clear bt u cn c tht output is in mv and i/p is in V.

What can be the problem in this?

regard the components except R & C as simple buffer/repeater/driver or inverter!

Thank you!

Distributed RC model

I figurd d problem out!

The voltage supply was missing!

Now if i give voltage supply to each module of this circuit .i.e. inverters & drivers .. CADENCE giv error

&

If i giv it on top level then
will i be able to debug the circuit?

I am checking the output of first inverter and it gives output in mV instead of inversion!

However the final output is similar to input but delayed as anticipated..

Please give comments!
