WebAug 2, 2011 · Timing paths in a sample circuit. The figure 1 has 2 timing paths: Path 1 from the positive-triggered register (1) through logic A, to a negative-level latch (2), while Path 2 is from the latch, through logic cloud B, to a positive edge triggered register (3). Let us examine this simple example to illustrate borrowing time to compensate for the ... WebICC command: check_timing. Library checks: It validate the library i.e. it checks the consistency between logical and physical libraries. It checks the qualities of both libraries. check_library: This command shows the name of the library, library type & its version, units of time, capacitance, leakage power, and current.

A transition on the reference event (input signal) establishes a reference time for changes on the data event. A transition on the data event (input signal) initiates the timing check. The limit and treshold are delay values. The notifier is a reg variable. lochgelly medical practice phone number
