摘要： In a method of generating variation-aware library data for statistical static timing analysis (SSTA), a “synthetic” Gaussian variable can be used to represent all instances of one or more mismatch variations in all devices (e.g. transistors), thereby capturing the effect on at least one timing property (e.g. delay or slew). By modeling device mismatch with synthetic random variables, the variation behavior (in terms of the distribution of delay, slew, constraint, etc.) can be interpreted as the outcomes of process variations instead of modeling the variation sources (e.g. transistor shape variations, variations in dopant atom density, and irregularity of edges).
摘要翻译：在用于生成用于统计静态时序分析（SSTA）的变异感知库数据的方法中，可以使用“合成”高斯变量来表示所有器件（例如晶体管）中的一个或多个失配变化的所有实例，从而捕获效应至少一个定时属性（例如延迟或转动）。通过对与合成随机变量的设备不匹配进行建模，变异行为（根据延迟分布，压摆，约束等）可以解释为过程变化的结果，而不是对变异源进行建模（例如晶体管形状变化，变化掺杂剂原子密度和边缘不规则）。

摘要： In a STA method, after accessing data sets regarding the IC, vectors of the data sets for STA can be generated. Each vector can include a base value and a plurality of tokens, wherein each token is quantized. For each vector, the data of the vector can be adjusted. Adjusting can include shifting a predetermined token to zero and adjusting the base value and remaining token values based on the shifting. Incremental compression can be applied within the vector by storing each token value as a difference versus its previous token value. Differential compression can then be applied by storing each token value as a difference versus a corresponding token value in a predetermined reference vector. A resulting vector can be stored. At this point, an operation for STA can be performed using multiple resulting vectors without de-quantizing or decompressing.
摘要翻译：在STA方法中，在访问关于IC的数据集之后，可以生成用于STA的数据集的向量。每个向量可以包括基本值和多个令牌，其中每个令牌被量化。对于每个向量，可以调整向量的数据。调整可以包括将预定标记移动到零，并且基于移位来调整基值和剩余令牌值。通过将每个令牌值与其先前的令牌值相比较，可以在向量内应用增量压缩。然后可以通过将每个令牌值与预定参考向量中的对应令牌值相差来存储差分压缩。可以存储所得到的载体。此时，可以使用多个结果向量执行STA的操作而不进行解量化或解压缩。

摘要： A method of performing simultaneous multi-corner static timing analysis (STA) on a design for an integrated circuit is provided. This method can include reading design data including a netlist, parasitics, and libraries at a plurality of corners. Each corner can represent a set of process, temperature, and voltage conditions. Using the design data as inputs, a plurality of operations can be performed to generate timing reports regarding the design at the plurality of corners. Notably, each operation has a single control flow and uses vectors of samples for performing the plurality of operations. Each sample is a value associated with a corner. This method minimizes computational resource and memory usage as well as accelerates the turn around time of multi-corner analysis.
