cadence results dose not change by changing the circuit

[shivaamordad]

hi every one
i have a really strange problem
when i change my circuit to see the effect of it, the results dose nOt change and i am really confused.
for example when i change the capacitor value from 500f to 2p i have an error, and when change back to 500f again i have that error, and this error occur in the next simulations

can u help me?

regards

hi
your question isnt clear!
do you have error with 500f or no??
