Problem with signal Length in xSignals PCB panel

[[email protected]]

dears
I have seen an inconsistency in the signal length calculation of xSignals. as you can see i have defined four xsignals between two so8 ICs. i think the signals length for all nets must be equal but you can see that Altium don't consider resistor length.
what is your comments?

thank you.

If these signals need to be same length, you probably need to include resistors in all of them (e.g if you have D0 - D7, then you may need resistors in all data lanes, not only in D0 - D3).

So, in reality this is not a problem - just be careful if some groups have resistors and others not and there is relation ship between them.

thank you Robert
it's true, But why ÙŽAltium did not consider the series component length.e.g if we want to length match D0-D7 with CLK that may have some additional series/parallel components, In that case, we will have problems. anyway thanks for your reply

I guess, it is not so simple to say what will be the exact delay in that specific component - so there is no really way how Altium could calculate the "missing" length. You could maybe somehow use package in length, but that could be confusing (especially for people who will be re-using your components or your designs). Simple way to handle this, is just to be aware of the length in resistors and add this to your calculation of clk length.
