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

  • Tim,

    Does'nt the Reactive region come into picture after the blocking and non-blocking assignments have been done in the

    stratified event queue? I understand that the reactive region comes after the active region and programs work in the reactive region of the queue so that by that time all blocking ,non-blocking and continous assignments have been evaluated.

     Please correct me if i wrong --The active region is the region where the continous assignments , blocking assignents and non-blocking assignments are evaluated in order specified above.The assertions execute in the observed region which follows after the NBA are evaluated and assigned,the reactive region follows the observed region where the 'program' block comes into picture.The testcase is written in the 'program' block and this is because by that time all continous assignemnts , blocking and non-blocking assignments have been evaluated and assigned and this avoids user induced races.
