1)Elmore delayElmore延迟 1.Finally,on the basis ofElmore delaymetric the impact of random processes variations on interconnect delay is analyzed,and the method to estimate the statistical characterizations of interconnect delay in the presence of process variations is presented.考虑了互连线工艺变化的空...
下图互联线延迟可以表示为: Delay=R1*C1+(R1+R2)*C2+……+(R1+R2+……+Rn)*Cn =Rwire * ( Cwire / 2 + Cload) 可以看出Delay和RC乘积正相关。 人们实验发现互联线Delay正比于互联线长度L的平方(Delay~L2),这也是长互联线中间加buffer修时序的原因。 1.3.RC Corner 由于工艺波动的存在,导致互连线工...
等效成一个R一个C的话这个tao就是RC的乘积，而传播延时delay=0.69tao
Next, using the Elmore delay coefficients, the embodiment computes a set of delays based on the representation, wherein each delay in the set of delays corresponds to a delay between the driver pin and a corresponding load pin in the set of load pins. As load pin capacitances change during...
The Elmore Delay Model is a commonly used delay model for clock network synthesis in Computer Science. It approximates the delay of a step response in a tree of lumped RC elements by using the mean of the impulse response. This model is particularly useful for computing the 50% delay of ...

The Elmore delay is an extremely popular timing performance metric which is used at all levels of electronic circuit design automation. It is provably an upper bound on the actual 50% delay of an RC tree step response and also holds for input signals with finite rise time. A lower bound on...
A more accurate model is the Elmore delay model, which we will discuss here. 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...

We study the minimum-cost bounded-skew routing tree problem under the pathlength (linear) and Elmore delay models. This problem captures several engineering tradeoffs in the design of routing topologies with controlled skew. Our bounded-skew routing algorithm, called the BST/DME algorithm, extends ...
