The clock design for the first implementation of the IA-64 microprocessor is presented. A clock distribution with an active distributed deskewing technique is used to achieve a low skew of 28 ps. This technique is capable of compensating skews caused by within-die process variations that are becoming a significant factor of the clock design. The global, regional and local clock distributions are described. A multilevel skew budget and local clock timing methodology are used to enable a high… CONTINUE READING
