Eventhough I connected the nets, Its showing unrouted net constaint. What am I doing wrong here ?

    Taking a wild guess, I would think maybe you forgot to check the box to make them plated through holes?

    GND12 and GND are two seprate grounds. I want isolation between them.

    Hi,

     

    This thread is confusing to me.  Can you describe the issue more clearly. Is there a report file you can look at that says what net is not fully routed?

     

    If you are getting an unrouted net constraint error then perhaps you can use the PCB tab to see what are the routed and unrouted lengths of the various nets on the design.  To do this select the PCB tab.

     

    1) from the tool ribbon pick the View tab then PCB to hide/unhide the PCB tab.

    2) From the drop down box choose Nets to show the nets in the design.

    3) you should then see a list of all the nets with their routed and unrouted lengths.

     

    You can sort the list of nets by clicking the columns headers to see the longest un-routed nets.  If you think all are connected and this shows a non-zero number in the un-routed net value then you can investigate or post that information.

    While testing this feature I see a potential problem.  I made two segments of one net just barely touch each other and it is showing them as connected with 0 length unrouted.  However, if you did this on an actual PCB there is a chance it would have insufficient copper connecting these.  This might happen, for example, if you connected a net to a pad on a component and then nudged the component over such that the net ended up just barely touching the pad.

    Here is a close up showing the hot spots and just how poor a connection these might have but still say they are routed.  If I reduce the route trace widths just slightly then the unrouted connection length changes from 0 to 11.528mil.

    Have a look at Design Rules > Routing > Width .... set widths appropriately and select "Check Min/Max width for physically connected copper"

    I have checked the PCB tab. Its showing routed.
