Summary:The article continues the study of modal reservation (MR) - a new method of cold redundancy of circuits that simultaneously improves electromagnetic compatibility. The results of quasi-static simulation of a double-sided printed circuit board with a triple MR are presented. First, a lossless analysis was carried out, after which the per-init-length electrical parameters of the structure and the bend were obtained with two sets of parameters. Then, linear combinations of modes are determined that give the greatest distortions in the time-domain characteristic. Then, a lossy time-domain analysis was performed, after which the N-norms were measured. The protective characteristics were analyzed and showed that the maximum amplitude of decomposition pulses at the far end of the structure increased by a maximum of 27%. The signal integrity analysis was performed, for which the cutoff frequency was determined from the frequency response, and the parameters of the excitation pulse were obtained from it. It is shown that it is not distorted in the structure before and after failures.
