Abstract: A method is described for simulating the f-sigma timing path delay of an integrated circuit design when local transistor variations determine the stochastic delay. This is achieved by determining an estimated delay time for a first timing path using non-linear operating point analysis of local variations (NLOPALV). An operating point is calculated for each cell that is included in a timing path in the integrated circuit design. The f-sigma operating point of a cell-arc is a point on the cell-arc delay function (CADF). An f-sigma delay value is determined for each cell using the selected operating point on the CADF of the cell. The determined delay values of the plurality of cells in the timing path may then be combined to predict the estimated delay for the entire timing path. The method may be extended to deal with slew rate, predict hold time statistics, prune paths, and deal with convergent paths.
Abstract translation: 描述了当本地晶体管变化确定随机延迟时模拟集成电路设计的f-sigma定时路径延迟的方法。 这通过使用局部变化（NLOPALV）的非线性工作点分析来确定第一定时路径的估计延迟时间来实现。 为集成电路设计中的定时路径中包含的每个单元计算工作点。 电池弧的f-σ工作点是电池电弧延迟功能（CADF）上的一个点。 使用小区的CADF上的所选择的操作点为每个小区确定f-sigma延迟值。 然后可以将定时路径中的多个小区的确定的延迟值组合以预测整个定时路径的估计延迟。 该方法可以扩展以处理压摆率，预测保持时间统计，修剪路径和处理收敛路径。

Abstract: An audio processor (1) includes a first filter coefficient calculator (31) that calculates a first filter coefficient so as to correspond to first gains for respective bands set by a user, a second filter coefficient calculator (32) that if values of third gains for respective bands of the first filter coefficient are greater than an absolute value of a second gain set by the user, calculates a second filter coefficient by limiting the values of the third gains for the respective bands to the amplitude value of the second gain, and a filtering unit (35) that filters an audio signal that has been transformed into a frequency-domain signal, using the second filter coefficient.
