For some clock net, some of designers prefer to add a T filter to avoid EMI issues. Because other nets needed to match length with it, so it's welcomed to combine a total Enet from driver to receiver. However, it's not supported in Expeditionpcb, the topologies see below. The only workaround is changing C's RF to make CES doesn't treat it as passive, but this workaround have serious negative effects on ECO. Is there a better to do so?
