With a hammer? Seriously, most autorouters you are likely to afford have these problems. Worse, VCC and Ground are "just another signal". It will cheerfully put a high current consumer on the end of the pipe with it's VCC and ground currents screwing up everything inbetween. I have an autorouter, I use it mostly to check where the board may be too dense. Then I manually route the highest frequency and current tracks, then VCC, Ground, and any other power supplies, then the lower and lower speed signals. Each track is considered for EMI and balanced against it's neighbors. You won't get that out of ANY router I've ever heard of. uP xtal caps need to return to the uP ground on a separate track, not one that visits some other point. VCC needs to route to a cap AT the ground pin, and from there up to the chip's VCC pin(s) I've never seen a router where you could teach it things like this, and if they exist, I bet I can hand route it in less time than it takes to teach the system all the rules for a particular board. The autorouter can complete simple boards, but usually they are SO simple they aren't worth making. I usually see the autoroute crowd sharing a lot of members with the "we've got big FCC problems" crowd.
