Time-based encryption in simulations?

Hi folks, I'm trying to think of a solution to make time-based simulation IP (verilog). We use vencrypt to protect the ip already. I was thinking about the possibility of using system call...

We do something like that in synth already. My hope was for a simulation solution

Use an assertion based on the counter? But of course an hour of real time is an infinity in simulation time :)

Are PLI calls supported in the simulators you expect to use? Perhaps you could do what you want that way, but at least its hidden inside your source. Why PLI? Well, you if you're going to make OS calls, I think that is your only option.

Cheers,
