forcing node voltages for ac analysis

Is there a way to force the nodes to some value (obtained from spectre.fc - after running the transient analysis) And then use that spectre.fc to force all the nodes to certain value and ask AC Analysis to use that as dc operating point to run the sweep ? I want to use this for my DAC simulation (PGA) The gain changes after each clock falling edge, so I want to capture the transient time @ Clocking edge, and get spectre.fc and use that spectre.fc for the AC simulation to see the gain. Thanks, Ramesh
