Capacitive coupling and inductive coupling are the two main factors in the occurrence of crosstalk fault in the communication bus. Among the various methods for reducing crosstalk fault, Crosstalk Avoidance Codes (CAC) codes are effective. However, with technology scaling, CACs are not able to prevent inductive effects. The proposed CACs methods are mainly based on capacitive coupling and do not consider inductive effects. To overcome this issue, a coding method is presented to avoid crosstalk fault called Joint Capacitive and Inductive CAC (JCI-CAC). The JCI-CAC coding reduces crosstalk faults by removing patterns of inductive coupling as ′ 11111 ′ and ′ 00000 ′ and capacitive coupling as ′ 10101 ′ and ′ 01010 ′ . The JCI-CAC offers a new method to generate a new numerical system for data encoding that has a low computational overhead so that it can be used for any desired width of the communication bus. The simulation results of the proposed JCI-CAC mechanism are investigated in different criteria of delay, power consumption and area overhead. The simulation results provide less power consumption in JCI-CAC than other recent approaches. There have also been improvements in overhead area and critical paths in JCI-CAC coding. The main novelty of this paper is to provide a new numerical system and a new coding algorithm with minimum cell area overhead and power consumption, considering inductance coupling in addition to capacitive coupling. Based on simulation results, power consumption of JCI-CAC in the 8-bit and 16-bit bus is reduced by up to 20% compared to SOTA and FPF (PS-Fibo, S2AP, Improved Fibo-CAC, Fibo-CAC) codings. Also, cell area overhead in JCI-CAC compared to SOTA coding in an 8-bit bus is reduced by 4.8%.
