Can SV detect integer variable's changing

[mrforever]

Hi, SV experts

Can SV detect integer variable's changing? if have the code like this,

integer a;

@(a) begin

do_function0 ;

end

do_function1;

how does it behave? will it execute do_function0 when "a" changes, while execute do_function1 when “a" doesn't change ?

thanks for the answer.

You'll need to show more context. Is this code itself inside another procedural block? Event controls in front of statements behave like a separate statement, and should be read as "wait for a change on 'a', then execute the statement that follows.

task A; // or begin

@(a) // wait for a change on a

do_function0;

do_function1;

endtask // or end

In a procedural block of code, each statement is executed when the previous statement completes.
