Latest Patents

Verock's latest patents include an invention that allows for multiple layouts for a schematic in hierarchical logical-to-physical checking on chips. This innovation introduces an EQUATE property into the layout cell data for a layout design, enabling the identification of the schematic corresponding to the layout design. Instead of requiring the layout cell to be exploded for flat checking, the layout cell instances can be checked hierarchically. This method allows for one instance to be checked internally for compliance with design rules while the remaining instances are verified for proper connections to neighboring cells. Consequently, new layout cell designs can be created as needed without the necessity of rerunning schematic checking tools.

Another significant patent by Verock allows for hierarchical logical-to-physical checking on chips. In this invention, layout cells that share the same name as their corresponding schematic are checked hierarchically. A single instance of a specific layout cell is checked internally for compliance, while other instances are merely checked for proper connections. Layout cells that do not match any schematic name are automatically exploded for flat checking at the transistor level. This approach preserves hierarchical checking for the majority of layout cell instances, while also accommodating special layout requirements for a smaller number of cases.
