LM61460-Q1: LM61460AFS-Q1 PSpice model Steady state parameter definition

Hi Yuriy,

I've contacted the PSPICE support team and will get back to you once I have more feedback on this error message.

Expect to hear back by tomorrow.

Regards,

Jimmy 

Hi Imran,

I haven't seen Fig.1 and Fig.2 you have provided.

Nevertheless I have defined Steady state as either  "0" or "1" before I sent my request to E2E

due I found the same recommendations in an other forums.

But in both cases The simulation was aborted with the same error message:

X_U2 0 N45567 N45450 N46087 N47156 0 0 N45433 N43822 N46326 N45216
+ N46634 N43582 N43582 LM61460AFS-Q1_TRANS PARAMS: STEADY_STATE=0

Reading and checking circuit
ERROR(ORPSIM-15167): Undefined parameter: steady_state.
Circuit has errors ... run aborted
See output file for details
INFO(ORPROBE-3188): Simulation aborted

Can you please send me figures you mentioned and or instruction, how do I need perform changing of model parameters?

Thank you.

Yuriy
