but how do i really know whether or not the connections that are made in my schematic are the same as the ones that i now have in front of me on the pcb layout screen?
i followed the yellow net lines which act as markers but i really feel i need to be sure b4 i commit to manufacture.
does any reader know how i do this interconnectivity check?
one thing you could do is compare both schematic and PCB, there must be a design comaprison option in it, but as these are already syncronised it wont show any error(and if it shows then your fear is right)
other thing you could do is generate the netlist from sch and PCB and manually check for the particular connections you are worried about .
Switchers are usually layout-sensitive. I.e. performance and (especially) EMI may depend on the layout significantly. If the datasheet for your switched has a recommended layout - follow it closely.
regarding poor layout problems........and the conducted emission problems they give....is it possible to have poor layout and use common and differential mode filtering to filter it away?

Sometimes it's possible to filter out the conducted EMI. But I've had horror stories where such approach was difficult. For example, I've seen conducted EMI propagate through ground plane.
If you post your boost schematic or a part number for your boost converter/controller, we might help you get more prepared.
