Result Interpretation

Systems-Level Signal Integrity Crosstalk Margin Evaluator calculator computes Crosstalk Margin in V using the defined engineering formula and the input values provided. Crosstalk Margin is expressed in V. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Supply Voltage = 1.8
  • Induced Crosstalk Voltage = 0.12
  • Peak System Noise Floor = 0.05
  • Receiver Input Threshold Voltage = 0.4

Expected Result:

  • Crosstalk Margin = 1.23

Engineering Interpretation:

Under the given input conditions, the calculated result is: Crosstalk Margin = 1.23 V.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

crosstalk margin = supply voltage - abs(induced crosstalk voltage) - peak system noise floor - receiver input threshold voltage
