摘要
A computer-implemented method includes identifying a noise cluster, representing the noise cluster according to a variational model, projecting the variational model onto one or more corners to yield a projected noise cluster, and determining a computed noise for the projected noise cluster. Optionally, the noise cluster includes one or more noise cluster elements, and each of the noise cluster elements are expressed as one or more circuit element terms, according to a canonical form. Optionally, at least one of the corners is a bounding corner. For the bounding corner, the projected noise cluster is generated by maximizing the circuit element terms for those noise cluster elements that tend to increase noise, and by minimizing the circuit element terms for those noise cluster elements that tend to decrease noise, whereby noise is maximized for the canonical form. A corresponding computer program product and computer system are also disclosed.
