A method of performing a dynamic built-in self-test (BIST). The method includes performing a first test of a circuit on a semiconductor chip. The first test includes a first switch factor. The circuit during the first test is monitored with one or more sensors. A first sensor value of one or more sensors monitoring the circuit is determined. It is also determined whether the first sensor value is within a range of a programmable constant. A second switch factor is determined in response to determining that the first sensor value outside the range of the programmable constant.
