  • Patent number: 11210448
    Abstract: Embodiments provide for mitigating parametric yield loss of an integrated circuit (IC) design. In certain embodiments, a delay distribution associated with at least one cell disposed in the design is determined. A pin slack distribution associated with paths in which the at least one cell is disposed is determined. A residual distribution is determined based at least in part on the delay distribution and the pin slack distribution. Yield loss associated with the at least one cell is determined based at least in part on the delay distribution and the residual distribution. When it is determined that that the yield loss associated with the at least one cell exceeds a yield loss threshold, the at least one cell may be identified as a candidate for replacement with a replacement cell.

  • Publication number: 20210375607
    Abstract: Apparatus and method for processing an image-charge/current signal for an ion(s) undergoing oscillatory motion within an ion analyser apparatus. The method comprises: obtaining a recording of the image-charge/current signal (20a-20e) in the time domain. Then, by a signal processing unit, a value for the period (T) of a periodic signal component is determined within the recorded signal. Subsequently, the recorded signal is segmented into a number of successive time segments [0;T] of duration corresponding to the period (T). These lime segments are then co-registered in a first time dimension (t1) defining the period (T). The co-registered time segments are then separated along a second time dimension (t2) transverse to the first time dimension (t1). This generates a stack of time segments collectively defining a 2-dimensional (2D) function. The 2D function varies both across the stack in the first time dimension and along the stack in the second time dimension.
