waiting on an array of events

[hooman_hbi]

Hi,

 

In my design I want a to have a SC_THREAD which waites on an array of events. Now I am aware of the fact that I could OR the events with '|'. But that solution is not handy when one is dealing with a large number of events. So is there any better solution?

 

Thanks,

Hooman

Hi Hooman,

Please see sc_event_or_list for your requirement.

An example can be found here

You can also just make your SC_THREAD sensitive to each element in the array, since a process sensitive to multiple events is sensitive to the or of those events, e.g.

 

SC_THREAD(proc)

for (int i=0; i< 100; i++)

   sensitive << my_array_of_100_events;

Is there a preferred way of adding an event to the static sensitivity list for a single wait? I think it would be possible by ORing the static sensitivity list with another event, and sending the result to a wait. The problem is that I don't see an accessor function for a thread's sensitivity list.

 

I guess one approach is to hard-code an sc_event_or_list that includes the static sensitivity list, but that seems a little clunky.

 

sc_event_or_list or_list;

for (int i=0; i< 100; i++)

   or_list |= my_array_of_100_events;

or_list |= new_event;

wait( or_list );

 

 Is there a better way to add an event to the sensitivity list for a single wait?
