MicroCap simulation questions

There`s lot of people using MicroCap for simulating circuits so I guess this thread will be useful..

1. How to measure Output imedance vs Frequency?


- AC analysis from Fmin to Fmax.
- Short the input to ground.
- Apply an 1A AC current source at the output.
- The voltage across the current source is the output impedance in ohm, from Fmin to Fmax.

Applies to all Spice simulators, it's not specific to MicroCap.
 
Can someone please help to simulate this circuit in MicroCap:

U1 is CD4069 and pinout from left is 1-2-3-4


This circuit working nicely in real life, but I cant make it work in simulation...


Thanks,
