Design Data Scaling
You can use the XScale utility to change the scale of your design data. XScale scales objects in Virtuoso Studio Design Environment cellviews according to the magnification factor you specify. You can apply XScale to views or view types within a certain cell or an entire library.
In SoC designs where you are merging a digital platform design with a custom platform design, you might have a mismatch in the database units per user unit (DBUperUU) settings if your different design teams are using different standards. For example:
-
Library Exchange Format and Design Exchange Format designs in SoCE typically use a DBUperUU of
2000. -
Virtuoso Studio Design Environment custom designs typically use a DBUperUU of
1000.
You need to scale the custom design data to 2000 DBUperUU so that the digital library elements and custom design data can be used together in a mixed-platform design environment. You can scale all of your design and reference libraries including the PDK library.
To correct the mismatch in database units:
- Change the DBUperUU in the technology file.
-
Use
XScaleto scale the physical elements to compensate for the change in DBUperUU.
