Abstract: One example includes a testing method that includes connecting a capacitor having a first capacitance to an output terminal of an integrated circuit (IC). The method can also include generating pulse signal responsive to an enable signal provided at at least one input terminal of the IC and providing a drive signal to the output terminal to cause a linearly increasing voltage across the capacitor responsive to the pulse signal. The method can also include measuring a no-load delay. The method can also include measuring the linearly increasing voltage at the output terminal responsive to the drive signal. The method can also include determining a first capacitance charge time for the capacitor responsive to the linearly increasing voltage reaching a threshold and determining a second capacitance charge delay for a second capacitance based on the first capacitance charge time and the no-load delay.
