Could someone give a detailed guidance on how to simulate the following project in OrCAD Capture CIS Lite step by step?

Draw a schematics for static analysis of a diode. Simulate the circuit such that static characteristics of forward biased 1N4002 diode for three temperatures (75 , 25 and 125 degree Celsius) are obtained. On obtained characteristics, indicate what trace corresponds to what temperature, and then determine and display the value of threshold voltage for each trace. For the set point positioned at Vd=0.8V at temperature 25 degree Celsius and for voltage increment dV=+0.1V or dV=-0.1V determine the dynamic resistance of a diode and display it.

Note: This is not homework. I am practicing for exam.

Hi

I don't use orcad (I use LTspice), but you should:

Perform a DC sweep of the diode while forward biased.
Do this for each temperature. Use a stepping function for the different temperatures.
Calculate the resistance from the results.
