DtoA1.N1 forced to X state for bias point, Warning


I am using UC1825 and whenever I am connecting my current shunt output as a feedback to the IC. I am getting this error.

WARNING(ORPSIM-15202): X$X_U7.N665691_DtoA1.N1 forced to X state for bias point

Pspice runs but doen't give proper output.

What is DtoA1 and how to work the digital and power electronics toghther?

This message indicates simulator is not able to solve the circuit for Bias point analysis and it has forced that specific node to X state. You may want to check your circuit for proper value, connectivity and initialization at t=0. As such one need not do anything special to simulate power electonics and digital circuit together.
