cdsvias problems

fuelectronics

 Dear all,

I try to creat the vias in my own PDK,  so i goes to technology file manger to creat cdsvias. 

After that i return back to  Virtuoso layout editting, to press "O", it shows   NO CONTACTS/VIAS defined in constraint group.

I check the "Help", I should go to window>>contraint group manger for my vias defination, but i did not find this option in there. 

Do you have any idea to sovle this problem, let me get the required VIAS in the contraint group.

    Have you put these vias in the validVias section of the interconnect section of the constraint group (virtuosoDefaultSetup I think, though you may need to add them to other CG's also).

    Regards,

    Lawrence.
