When I do Assura LVS on the layout I got from P&R Encounter, the "unbound pins" error appears in the report. As the attached picture shows, the net marked as green color in both schematic and layout looks matching well. But it seems LVS cannot specify the pin ports from the instance of the standard cell layout? Can I ignore this error and trust that schematic and layout actually match? Thanks in advance.
Hi bjbitI think it is better to troubleshoot the error so that you can get lvs match. The error looks strange. Assura seems to be reporting. You should check the sdb and ldb netlists in the run directory to see why Assura is reporting pin errors.terminal>vldbToCdl design.sdb > design.sdb.asciiThe above cmd will convert the binary netlist to ascii format.Best regardsQuek
