Mask Design Verification

Verification products include both DRC and LVS. The LVS product includes a compare module to compare the extracted netlist to the reference netlist. Both products are integrated within the slam environment. Both are invoked from within slam. The results of the DRC product are stored in the database and may be reviewed with the VioVue which is part of the slam layout viewer. The LVS product generates a text error report in addition to the graphical error report. The LVS product can also generate a netlist from the layout in spice format.
