Auto route STOP at symbol boundary?

goofycat

Hi,

 

Although for top-level components, layout GXL works find and we can auto route connection, "auto route" does not appear to work between different level of hierarchies.

For example, in the attached screenshot, auto route does not connect top level FETS to the block in lower right.

Is this by design?

    Can't easily see the detail on that image (it doesn't seem to want to enlarge and it's a bit fuzzy) but this should work. I'm assuming there's no layout for the bottom right instance and so it's expanding to place two transistor instances inside? Or is there an existing layout for that sub-block? If so, are there pins on the layout?

    Not really enough info to go on, I'm afraid...

    Regards,

    Andrew.
