WebOct 17, 2010 · A master clock is a clock defined using the create_clock specification. 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.
