A One-Hot Encoding Approach for Signal Integrity Enhancement of Intra-chip Interconnects

As the density of package interconnect wires continues to increase and the operating frequency continues to increase, the performance of integrated circuit packages continues to improve. It also brings signal integrity problems, such as reflections, impedance mismatch, clock delay, and eye diagram distortion. Rongrong Ben et al. proposed four methods to optimize crosstalk ([1]).Hanzhi Ma et al. summarized the recent advances in the application of PEEC method in signal integrity analysis of neuromorphic chips based on memristors([2]). Manish et al. proposed a three-dimensional coplanar electromagnetic bandgap (EBG) structure to improve the signal integrity (SI) ([3]).One-hot coding is an approach often used for feature coding and is widely used in the field of machine learning and data mining 141 In this paper, authors apply one-hot coding to the circuit. Compare the signal integrity of one-hot coding circuit and uncoded circuit. The results show that one-hot coding circuits can enhance signal integrity.
