I am not clear on what you are asking. When you refer to “match the signal traces”, do you mean to make them the same length, or something else? And, to which signals are you referring: the signals from the sense resistor, or from the output voltage back to Vfb?
I can’t tell from your image where the inductor and the output are, and I’m not clear as to which signals you are referring. However, the TWO sense signals coming from each sense resistor should be routed in parallel as close as possible together along their route back to the Sense+ and Sense- pins. Furthermore, they should not be routed near any high-current paths, as this can cause unwanted coupling of noise back to the sense pins.
By keeping the traces routed as close together as possible, any noise that is picked up by one trace is likely to get picked up almost equally by the other, and since the Sense pins only measure the difference between the two signals, this common mode noise will tend to be ignored, compared to if only one of the traces picked up the noise.
Make sure you carefully read the layout and debugging recommendations on page 27 of the datasheet, the general layout diagram on page 28, and the application information on page 30 for guidance.
