The trick to SIM or even real circling approaches is to draw a mini Jepp chart and write on it all the points, distances, timings, heights, speeds, Flap and Gear extension points, wind, vertical speeds and so on
Certainly very impressive information but this bears out the point made by Tee Emm that circling approaches in the simulator as taught by some operators is nothing more than trick flying using instrument navigation to solve a visual problem.
I am not sure that reputable regulatory authorities would permit this. Certainly the Boeing FCTM section on circling approach procedure makes no specific direction in terms of FMC navigation in lieu of visual navigation. In marked contrast the FCTM does publish extensive information on FMC planning for instrument approaches. This suggests Boeing does not encourage heads down MAP reading during a visual circling manoeuvre?
