LTC7151S Pgood Signal not working in simulation


   I'm attempting to power sequence two LTC7151S converters using the Run and Pgood signals.  However, even when simulating a single converter, I can't get the Pgood line to cooperate.  I have the Pgood pin pulled high with a 10k resistor, however, the signal is kept low even when i'm within 7% of the setpoint.  I even opened the test fixture made by lt, and confirmed that the pgood line doesn't work.  What is my next step?

grammar error
