Accurate Circuit Verification

Calibre nmLVS enables accurate circuit verification because it is able to measure actual device geometries on a full-chip for a complete accounting of physical parameters. These precise device parameters supply the information for back-annotation to the source schematic and the comprehensive data for running simulations. In addition to working with Calibre xRC, Calibre nmLVS can also be used with third party parasitic extraction tools

Automate Advanced, Customer-Specific ERCs

Calibre nmLVS can now be enhanced with Calibre PERC (Programmable Electrical Rule Checker). With Calibre PERC, you can automate advanced, customer-specific ERCs to eliminate lengthy and error-prone manual checking. PERC recognizes grouped devices that are connected as you describe and measures geometrical data associated with the circuit topology.
