In reply to ramazankaan:

It is confusing what you are writing. Look to this piece of code:

 3'b111: begin 
                    example_vif.LA_EN <= 1'b1;
                    example_vif.data_bus <= req.data_bus;
                    example_vif.LA_EN <= 1'b0;
                 end

You are setting LA_EN to 1#b1 and afterwards in the same time step to 1’b0.
What you see seems to be correct.
