Supply change in post layout simulation
Feb 11th, 2022, 10:39pm
 
Hi everyone,

In the very last stage of a  phase generator that I have designed for a TI ADC, I see the following phenomenon. As you can see, supply (Second signal) changes with the input (First signal) in post layout simulation. Phase generator is connected to the SAR ADCs.
Could you please help me understand what is happening?

Thanks

Solved. The extracted file was corrupted! Using dspf extraction solved it. Supply nodes were floating!

Thanks,
Nilou
