Cadence Cross Review

💡 : While the cross() function is powerful for single points, it is often combined with other functions like delay() to build complex automated verification scripts.

Using the cross() function effectively requires careful setup of your Cadence Virtuoso environment.

: 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.

: If the function fails to find a point, ensure your threshold is actually within the signal's range (e.g., don't look for a 1V cross in a 0.8V signal). 💡 : While the cross() function is powerful

: Measures the time difference between an input crossing a threshold and an output doing the same.

Engineers rely on this function to automate measurements that would be impossible to pinpoint manually. Occurrence Number : You can find the nthn

: It is often used to "unwrap" periodic waveforms by finding cycle crossing points. Practical Applications in Design
