郁闷啊,pspice仿真学了半年了,竟然连一个中规模集成块都没仿真出来,每次都会出现类似这种东西:
ERROR -- Model IO_4000A used by X_U24.U4029ALOG is undefined
ERROR -- Model IO_4000A used by X_U24.U1FF is undefined
ERROR -- Model IO_4000A used by X_U24.U2FF is undefined
ERROR -- Model IO_4000A used by X_U24.U3FF is undefined
ERROR -- Model IO_4000A used by X_U24.U4FF is undefined
ERROR -- Model IO_4000A used by X_U24.U4029ADLY is undefined
请版主给予指点,谢谢.
