need help for PSPICE simulation error--unknown parameter

[leewan]

hello,can anyone help me to solve this error?i'm really running out of time. The PSPICE version that i'm using is 10.0, i downloaded the schemetic from ON Semiconductor .

ERROR -- unknown parameter


 

[Mr.Cool]

likely the problem is with component U1. try removing it from your circuit (temporarily) just to make sure this IS the problem. it should compile fine without U1.

then we can go from there..

 

[leewan]

without the U1(controller-NCP1608), there is free of error. The problem is without controller, the output waveform is totally invalid. There is no more any replacement controller. My project is doing Critical Conduction Mode Power Factor Correction.
