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...

Heh. We can timebomb the sim after a certain point sure, but up until that point the IP will work perfectly. And all it takes is rerunning the sim. I've tested $system calls on Modelsim SE and it's supported, but I can't say about the other flavors and simulators. Perhaps since Altera seems to be going the systemverilog route in the V family, there might be an SV solution for future dev.
