Measure performance metrics of SV-RNM vs VAMS models

Hi,

I am a student currently working on describing analog blocks with SystemVerilog using Real Number Modeling (RNM), which allows for discrete-time functional modeling of analog circuits and their behavior, enabling very fast event-driven simulation of the model. I already have Verilog-AMS models for these analog blocks, and since they are supposed to have much higher simulation costs, I would like to compare those to my SV-RNM models. Therefore, I would like to propose an approach to compare performance metrics between SV-RNM and VAMS models.

From what I could find on the net, it would be interesting to measure :

• the overal “stopwatch” time from start to end (“real”)

• the CPU time in user space of a single run (“user”)

• the CPU time in kernel space of a single run (“sys”)

The thing is that, I am using SimVIsion(64) to run my simulations, and I have no idea how to measure those. Does anyone know how can I measure this ?

Also, I didn't find that much resources on this topic, so feel free to let me know if you have any information, documents, or even contacts that might help me.
Thanks for your help.
