Abstract
	This paper investigates the case of providing functional safety simultaneously with electromagnetic compatibility of radio electronic equipment (èëè ÷åãî-òî äðóãîãî, êîíêðåòíîãî) by employing modal reservation (MR) technology. The presented (èëè proposed) algorithm analyzes structures with triple MR after various types of failure. This algorithm allows for the simulation, evaluation and selection of the optimal switching order for such circuits. It is built on the principle of evaluating the maximum voltage (Umax) at the output of the reserved conductor, and handles various types of faults and their variations at the end and along the conductor at an arbitrary location. Using this algorithm, we performed a quasi-static simulation of a specific structure with a triple MR and determined the optimal switching order that provides the minimum interference. For this structure, switching option 3 is optimal, since in options 1 and 2 after failure 1 there is a change in Umax from 0.238 to 0.325 and 0.272 V, after failure 2 - up to 0.411 V, and after failure 3 - presumably up to 1 V. The developed algorithm can be used for a similar analysis of any similar structures with MR.
