Systemverilog fork-join_none and forever block

[srish]

My code goes like this:

fork
begin
....
forever
begin
process 1;
if (some condition)
break;
end
.....
end
join_none

My doubt is if that "some condition" is met then will break will help to come out of forever block and fork-join_none block???? ........... fork-join_none has only 1 begin-end block......plz ans???

You will come out of the fork/join_none regardless of what is inside it because it dynamically spawns a process without waiting for it to complete. join_none means "wait for no processes to complete before continuing (re-joining) the current process".

The fork block has one statement inside it - a begin/end block - which means it spawns only one process. Lets name that block p1.

One of the statements inside the the p1 begin/end block is a forever looping statement.

The looping statement is another begin/end block.

One of the statements inside the the looping begin/end block is a break statement.

When the break statement executes, the forever looping begin/end block exits, and the next statement in the p1 begin/end block executes.

When the last statement in the p1 block finishes, the p1 process terminates.
