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

  • I would suggest using an incremental technology database. What that means is rather than attaching your design library to the technology library, use the reference option instead. This means that you have a technology file in your design library, but one that is mostly blank and will inherit from the technology library.

    You can then set up your coinstraint group (either by editing the dumped ASCII tech file from your library, modifying, and re-loading, and then saving the tech file), or by using the Process Rule Editor in the constraint manager in VLS XL.
