Symbolics and Translation to IC61

armthy

 Hello,

I have noticed that during IC51 to IC61 translation, some of the symbolic/symbolic arrays are unbound in IC61.

On further investigation, I have realized that this is due to incorrect usage of symbolics in IC51.  Instead of using Create->Contact the Symbolics have been added as an Instance. Since I have seen legacy designs that have this usage all over the hierarchy, I am wondering if any forum members has a template of skill code that can go thru a layout hierarchy and replace symbolic instances with the equivalent contacts.

I can run such a code in IC51, correct the layout hierarchy and then run the translation to IC61.

Appreciate any help on this.

Thanks!

  •  Hi Andrew,

     Thanks for your reply. If you place a instance array of a via in IC51 the objType is mosaicInst. This will not translate correctly to IC61. It will be unbound. If you use the "Create->Contact" and create a contact array, this will get translated correctly to IC61 as the vias will be now mapped to the one coming from the techfile via definition.
