Hi. I'm designing a buck regulator. I'm using IR2110 to drive high side mosfet as switch and low side mosfet as a freewheeling diode. schematic is attached. when I run it on PSpice the message come "there are no data values in section 1. ignoring this section". and output file message come "INTERNAL ERROR -- Overflow in device X_U1.E_MD3_DlyHS_ABM24, Convert". also that IR2110 that I downloaded contains two components one is the IR2110 itself other is Comp. what is comp. is it a subcircuit? does I have to use it as well for the circuit to operate properly.

I suspect, problem could be with IR2110 model. You may want to try simulating your circuit without this, just use simple E devices to get desired isolation.
