针对纳米CMOS电路连通域结构约束,该文提出了基于逻辑复制方法的电路等效变换技术以降低电路映射复杂性。首先通过对电路中所有的门扇出值进行排序来选定基准高扇出值;然后对于高扇出门单元通过二次方程式计算变换前后复杂度,对复杂度降低的高扇出门单元执行逻辑复制并进行扇出分割。与传统插入反相器方法网表转换法比较,结果表明使用该文提出的方法电路不仅更快速地被映射到纳米混合电路单元上,而且具有更好的时延特性。 Aiming at the structural constraints of the nano-CMOS circuits, this paper proposes a circuit-based equivalent transform technique based on the logic copy method to reduce the complexity of circuit mapping. First, by selecting all the fan-out values ​​in the circuit to select the reference high-fan-out value; and then using the quadratic equation to calculate the pre- and post-conversion complexity for the fan-out unit, and performing logical copy on the fan-out unit with reduced complexity Fan out the partition. The results show that the circuit proposed by this paper is not only mapped onto the nano-hybrid circuit unit more quickly, but also has better delay characteristics.
