1. A non-volatile computer readable medium storing instructions to determine jitter in a clock signal under test that, when the instructions are executed by a processor, cause the processor to:
determine two points of input-referred noise data for a crossing time, a first point of the two points being before the crossing time and a second point of the two points being after the crossing time, the crossing time being a time that a clock signal representation crosses a threshold value, the clock signal representation corresponding to the clock signal under test; and
determine a first time error associated with the crossing time using a displacement to the clock signal representation caused by the first point of the input-referred noise data, a displacement to the clock signal representation caused by the second point of input-referred noise data, a clock slew rate of the clock signal representation, a period of a sampling clock of an analog to digital converter used to generate the input-referred noise data, and the crossing time, the first time error indicative of a change in the crossing time due to the input-referred noise data.
