Abstract
In one embodiment, a method generally comprises importing a layout identifying routing information for a plurality of differential pair traces on a printed circuit board at a skew assessment module, receiving values for a plurality of skew parameters associated with fiber weave skew, receiving variation parameters from a database comprising data collected on fiber weave variation for one or more of the skew parameters, calculating a skew estimate for the printed circuit board based on the skew parameters and the variation parameters at the skew assessment module, and determining if the skew estimate is within a specified skew allowance for the printed circuit board.
