The truth is that you don't and this is fairly apparent when you find a buggy device and the vendor either shrugs it or threatens to sue you. (yes that does happen) You can build out of discrete logic. The opportunity for something dodgy to be built in at that level is unrealistic. Some military equipment still works on that principle.
