If you like in the Calibre Verification User's Manual section "Compare Layout Databases Using DBdiff", you'll see an example of just that:
Example: Generate a Calibre RVE Results Database (RDB) File
The following example shows how to use the DBdiff application to generate a RDB output file digblk.rdb.
dbdiff -system GDS -design DIGBLK_v2.gds DIGBLK -refdesign DIGBLK_v1.gds DIGBLK -rdb digblk.rdb
To view the layout differences in Calibre RVE, follow these steps:
- Open the design being evaluated in a supported layout viewer.
- Start Calibre RVE, using Verification > Start RVE from DESIGNrev, or using Calibre > Start RVE from other supported layout viewers.
- In the Calibre RVE dialog box, select File > Open Database. Enter the name of the RDB in the database field and select a database type of DRC/ERC. The layout differences are shown as checks in Calibre RVE. See "Using Calibre RVE for DRC" in the Calibre Interactive and Calibre RVE User's Manual."
Hope that helps-
