Length & Width
- Item: Input item name.
- Net: Select Differential Pair Net Group.
- Start Component: Upon selecting this option, a test will be performed between the start component and the end component.
- End Component: Upon selecting this option, a test will be performed between the start component and the end component.
- Filter: Enter a filter to choose differential pair net from the selected net group. Enter Base Net and Pair Net and click Add Filter. The Differential Pair Filter is added.
- Tolerance: Define tolerance measure base.
- Value: Tolerance value to measure an allowable length skew between nets in a differential pair.
- Via Existence: Via count check criteria. (Not Check/Min/Max)
- Via Qty: Specify the minimum or maximum numbers of vias.
- Report display highlights all differential pair nets. It is reported as failed if a length difference between the two nets in a pair is bigger than the tolerance.
- It is reported as failed if the number of vias does not match with the specified via count.
- Buried Via Merge: Enter a reference value to judge multiple Blind Via as one.
- Width: Upon selecting check, it fails if there is a region in which two nets have different widths.
- Pin Escape: Enter a radius of circular region around pins to be excluded for the rule check.
- Max Total Length: Check maximum trace length.
- Include Via Length: DFE includes via length for calculating trace length.
- Include Package Length: DFE includes package length for calculating trace length.
