The cross() function is primarily used within the Cadence Calculator to detect the precise time a signal passes a defined value.
: The tool uses linear interpolation between simulation data points; for high precision, use a smaller time step in your transient analysis.
: Designers can specify if they want to find rising edges, falling edges, or both. Occurrence Number : You can find the nthn raised to the t h power time a signal crosses a value (e.g., the 5th rising edge). cadence cross
: Use the cycle and time options within the function to handle periodic signals without manual counting.
: It is often used to "unwrap" periodic waveforms by finding cycle crossing points. Practical Applications in Design The cross() function is primarily used within the
Using the cross() function effectively requires careful setup of your Cadence Virtuoso environment.
: Calculates the duration between two crossing points (e.g., 10% to 90% of the signal swing). Occurrence Number : You can find the nthn
: Tracks variations in crossing times over many cycles to evaluate signal stability.
