Schematic bus terminals has no corresponding layout bus terminal definition

Hello ,

I am facing an issue where the CAS shows "Schematic bus terminals has no corresponding layout bus terminal definition" for all the Buses in the layout (imported using GDS)

Will be great if some solution can be shared ?

I am using IC618

thank you

    Hello,

    You can turn off this check if you don't want to interoperate your data with Innovus using Open Access.

    If you want to turn it off, in the CAS window turn off Implicit Bus.

    If you want to fix it you can go to the Annotation Browser click RMB on the marker for this issue and fix it by using update implicit bus.

    Thanks,

    Alex

    Also, you may be better off importing the data from the P&R tool using DEF format rather than GDS. GDS will lose and connectivity information, so isn't the best way into a connectivity-driven flow (you had another post asking something similar)

    Thanks for the reply , 

    I will try out these options. What output from Genus can be used instead of GDS for importing inside Virtuoso ?

    Also after importing GDS there were ungenerated pins showing up in CAS. So I used Tools -> Create pins from labels to for ungenerated pins .Is this approach fine to get connectivity information as well (flight lines etc..) for routing using the imported GDS?
