Geometric wire options (VLE)

sPoK

How can I set min. num. of cuts, wire width per metal, use of square collinear vias and other options for geometric wire without starting VXL, making my own contraint and setting it for default.

I assume that the geometric wire has the same properties (or most of them) as the "real" wire. 

Is this a bug or a feature? Since in Virtuoso L there is no Wire Asissitant to set all these options (IC6.1.5 ISR13).

Thanks

  • It's not a bug. You can create the constraint group in the technology library (maybe as an incremental technology database if you don't want to write to your PDK), either by hand, or using VLS XL to create the constraint groups. Then you can pick the constraint group when using VLS L.

    However, the power comes from using VLS XL. Is there a reason you don't want to use XL?
