Abstract
The possibility of designing a power supply circuit on a flexible-rigid printed circuit board to ensure the stable operation of DDR4 memory chips is considered. A pretopological modeling of a flexible-rigid printed circuit board was carried out, and a matrix of decoupling capacitors was formed. An automated placement of elements on a flexible-rigid printed circuit board was performed, accounting for the criteria of thermal and electromagnetic compatibility using a two-level genetic algorithm. The features of tracing the power circuit are considered. A post-topological modeling of a flexible-rigid printed circuit board was carried out, confirming the effectiveness of the proposed approach to designing and choosing mathematical models.
