When a new clock is generated in a design that is based on a master clock, the new clock can be defined as a generated clock. For example, if there is a divide-by-3 circuitry for a clock, one would define a generated clock definition at the output of this circuitry. does facebook allow pornographyhttp://www.ids.uni-bremen.de/lectures/lab_ic/2_tut_intermediate/ f1rst newsWebFeb 4, 2024 · It starts with the clock root pin defined, for which we want to create conventional clock tree structure and H-Tree.
