I tried to simulate MOD-16 asynchronous counter (see attached figure) using Pspice Schematic (Orcad v10.0). Pls find the schematic and simulation files in the RAR file. When I run the simulation, I got the error as shown in the attached figure. Would anyone pls advise what's wrong with my schematic or settings? Thanks.
 

every input pin must have a input voltage the must not be in air because their input voltage bios the input transistor
clr and preset pins too
your preset pins in stage 2 and 3 must contact to earth or 5 voltage

output pins can be in the air without problem
