Variables Used
Agressor Voltage - (Measured in Volt) - Agressor Voltage refers to the avoided voltage in a CMOS circuit, which is typically a small positive voltage added to the input signal to avoid unwanted triggering of the circuit.
Victim Voltage - (Measured in Volt) - Victim Voltage is calculated when the victim being actively driven, then the driver will supply current to oppose to reduce the victim's noise.
Ground Capacitance - (Measured in Farad) - Ground Capacitance is the capacitance at the ground of the CMOS Circuit.
Adjacent Capacitance - (Measured in Farad) - Adjacent capacitance is the capacitance at adjacent point.
