Abstract
A semiconductor integrated circuit includes a boundary scan register and a plurality of local monitor circuits. The local monitor circuits are arranged individually about peripheral circuit regions of a semiconductor integrated circuit, being spaced from the boundary scan register, in order to measure and predict operation speeds in accordance with local on-chip process variations at a plurality of locations on the peripheral circuit regions. The operational speed of the semiconductor integrated circuit is determined by taking correlations into account between an overall signal delay time measured by the boundary scan register and local signal delay times measured by the respective local monitor circuits.
