Systems and methods for timing a linear data path element within an integrated
circuit design are provided. A representative system includes a computer and a
memory element associated with the computer. The computer includes logic for receiving
information describing the integrated circuit design. The integrated circuit design
includes a description of a signal-timing path and the clock distribution system
across the integrated circuit. The memory is configured with executable steps to
generate a model of a signal that traverses a signal-timing path that is coupled
to a linear element. The model includes a mechanism for simulating clock signal
operation over a plurality of clock distribution structure types. A representative
method includes the following steps: acquiring circuit information; identifying
a signal path within the circuit information; recognizing when the signal-timing
path is coupled to a linear element; associating a clock uncertainty with the clock
signal; determining a confidence interval for the signal-timing path responsive
to the recognizing step, wherein the clock signal is propagated along the signal-timing
path; and associating the confidence interval with the signal-timing path.
