A method for determining mismatch variation of circuit components in a circuit is provided. The method includes determining a mismatch contribution for a specification of an integrated circuit design and displaying a list of components in the circuit design sorted according to the mismatch contribution. The method also includes displaying an adjustable scale for a size of the component, modifying the circuit design according to with the size of the component adjusted according to a user input to the adjustable scale, determining an adjusted mismatch contribution of the component, and displaying in the list of components a modified value of the mismatch contribution, and a modified value of an overall standard deviation for the specification in the circuit design.

Interactive platform to predict mismatch variation and contribution when adjusting component parameters

A method of processing signals includes: sampling multiple signals, where each sampled signal includes multiple signal values and corresponding time values; partitioning the sampled signals into multiple partitions, where each partition includes signal values and corresponding time values for signals having identical time values within a partition time interval and where at least one additional partition is formed when two sampled signals diverge from identical time values; and saving signal values and time values from partitions in buffers corresponding to the partitions, where the buffers represent allocations of memory for saving partition values.
