Abstract
One means of reducing pessimism in crosstalk analysis is to consider timing orthogonality. While earlier works have addressed the temporal alignment of timing windows [1, 2, 3, 4], these treatments have overlooked one key point. Crosstalk noise failures are frequency dependent. A chip that functions at one frequency can fail due to crosstalk noise at faster and slower frequencies. Moreover, because system developers and manufacturers need chips that operate over a wide range of frequencies, noise analysis tools should guarantee a wide range of operation. In this paper, we explain this phenomenon and propose a simple procedure to include timing information and guarantee functionality from dc to f{max}.
