I have made a simulation for converting +12 DC to +5 volts using MC33063 from ONsemi; Cadence Orcad Capture generates the netlist well but pSpice calculations do not converge. Is there anyone to help the simulation converge, please? The whole project is attached.

Make sure in your schematic you are using the components with PSpice model attached.

There is no error indicating the library problems. My problem is on convergence and unacceptable results.
