Run/Plot Single Transient Simulation Multiple Times

What is varying between these runs? It's not clear what you are doing here. You are talking about running a single simulation 100 times - presumably something must be changing (otherwise why would you bother). It's also unclear to me what would be the issue with plotting the results - this should just work. What are you trying and what doesn't work?

The switching current is defined as a stochastic parameter (exponential & normal distributions), hence the switching duration & peak current values are  expected to change with every run. The device is modeled using VerilogA, and I'm trying to simulate this simple circuit.

How do I run the same transient simulation several times?

I can think of a couple of potential options and will let you decide which, if any, might be best for your application.

1. If neither your verilog-A model nor R3 are temperature dependent, you can set up an Assembler corner run with the temperature varied from 0 to 99 with a 1 degree increment

2. Add a voltage source whose DC value is a variable "sim_count/100" [1] and connect it between ground and new node "vsim_number". Connect new node "vsim_number" to a "no-connect" or, say, a 1 K resistor R1 to ground. Sweep the variable sim_count from 0 to 99 with an increment of 1 to perform 100 simulations. This will allow you to easily identify each simulation corner with the variable sim_count's value.

I hope I understand your intent and these two thoughts provide spark an idea or two for you.

[1] I include the divisor of 100 to limit the output voltage source to less than 1 V. 

Keep it even simpler - just add a dummy variable and sweep that. There's no need to actually use it in the circuit or changing anything with an actual effect like temperature.

Of course, you're going to have to make sure that your random generator gives different results each time. Normally they wouldn't unless the seed is set differently - so maybe you end up making the seed a variable and sweeping that?
