Communication between e and SV

YM KIM

Hello all,

I'd like to implement interface channel between e and SV and followings are candidates. Which one do you think the most efficient?
Or else ways? Any ideas will be welcomed.

1. Using ports in Specman 

2. DPI

3. VPI

Thank you.

  • I'm no expert, but what I've seen so far suggests DPI can do the majority of things an everyday user would want, but sometimes you might need to augment it with some VPI to do things to the simulator core, e.g. turning on/off assertions or executing simulator-specific features like TCL commands. The answer will really depend on what you need to achieve.

    If what you're most worried about is how to pass transaction data between e, SV and C, I'd expect the TLM ports to be of most use, since they are truly language-neutral and were designed for that purpose. It also means less work yourself to interface the data types etc.
