埃尔莫延时分析是一种估算电子系统中RC网络延迟的简单方法。对于树状网络，通过将每个段的电阻乘以其下游电容来找到每段的延迟，并从源到汇点累加这些延迟。这种方法避免了对RC网络进行数值积分或微分方程的耗时计算。总结来说，从开关源（根）到第i个节点的传播延迟等于该节点电容Ci与从源到该节点路径上电阻之和的乘积。Vout的埃尔莫延时表现为R1C1+(R1+R2)C2。
- Elmore delay is a simple approximation to the delay through an RC network in an electronic system.
- For tree structured networks, find the delay through each segment as the R (electrical resistance) times the downstream C (electrical capacitance). Sum the delays from the root to the sink.
- The Elmore delay analysis model estimates the delay from a source (root) to one of the leaf nodes as the sum of the resistance in the path to the ith node multiplied by the capacitance present at the end of the branch. It provides a simplistic delay analysis that avoids time-consuming numerical integration/differential equations of an RC network.
- In other words, the propagation delay from a switching source (root) to an ith branch node is given as the product of the capacitance “Ci” of the node with the sum of the resistance from the source to the node, Ris.
The Elmore delay for Vout is given as tpd = R1C1+(R1+ R2)C2
