 The difficulties faced are:
1. Understanding how the tool works
2. How to input the values for components

The circuit details are
1. power suppy: 1.65 v
2. gain band width product: 100Mhz
3.slew rate: >= 50 v/us
4.output voltage range: >= 2 vp-p
5.compensated capacitor: 2.3 pf
resistor : 519 ohms

simulation results:

1. open loop gain = 70.97 db 
2.phase margin = 76.5 degrees
3.settling time = 22ns
4.total power consumption: 16.5 mv
