Active/Reactive regions

Leo1008

 Hi,

 I have often come across the terms active and reactive regions of simulation in many of the SV tutorials, but haven't figured what they actually mean yet. Can you please elaborate on these.

Thanks

  • Yes, I wasn’t clear and you are correct. The reactive region comes after NBA, blocking assignments and continuos assignments. However, in the case of assertions it uses that values that were sampled before those events.

    Program blocks also work in the reactive region. I’m not sure if the 1800-2009 standard addressed program blocks, but I know there were originally many issues in using program blocks because of inconsistencies in the LRM and how they were supposed to be implemented. Since OVM does not require the use of program blocks, this has not been a concern.
