Impact of Place and Route Position on FPGA Electromagnetic Emission Characteristics

The continual advancement in the integration density of integrated circuit (IC) and their decreasing size augments device performance. However, this progression introduces pronounced challenges in terms of electromagnetic compatibility (EMC). EMC issues have now become pivotal factors that influence not just individual circuit functionalities but even the overall system's operation. Given the significance of this, the study of electromagnetic characteristics of IC is of great significance. This paper investigates the electromagnetic emission (EME) Characteristics of FPGA from the perspective of place and route (P&R) positions. The obtained results indicate that alterations in the P&R positions can affect the overall EME level of the FPGA. Placement and routing on the lower side of the FPGA will result in a smaller EME level. While such positional changes don't substantially impact the EME spectral characteristics of the FPGA, they do affect its spatial distribution characteristics of the EME.
