1. A method for a circuit module to have reliable margin configuration; the circuit module comprising a main circuit, a first auxiliary circuit and a second auxiliary circuit; the main circuit comprising a first node, the first auxiliary circuit being coupled to the first node, the second auxiliary circuit being coupled to the first node and a control signal, and the method comprising;
causing the first auxiliary circuit to be on; and
when the first auxiliary circuit is on, causing the second auxiliary circuit to be on or off in response to whether the control signal is of a first level or a second level; wherein:
when the first auxiliary circuit and the second auxiliary circuit are both on, the first auxiliary circuit and the second auxiliary circuit jointly cause an operation parameter of the main circuit to be a first value;
when the first auxiliary circuit is on and the second auxiliary circuit is off, the first auxiliary circuit causes said operation parameter to be a second value different from the first value; and
an operation margin of the main circuit covers a range between the first value and the second value.
