clocks

An essential part of timing analysis is accurately specifying clocks  and clock effects, such as latency (delay from the clock source ) and uncertainty ( amount of skew or variation in the arrival of clock edges) . You can specify, report, and analyze clocks are described in the following sections:

-- clock overview

-- specifying clocks

-- specifying clock characteristics

-- using multiple clocks

-- clock sense

-- using pulse clocks

-- timing PLL-Based designs

-- specifying clock-gating setup and hold checks

-- specifying internally generated clocks

-- generated clock edge specific source latency propagation
