WARNING (XSTRM-81000): Via detection cannot create new via definition for "PO_M1p_pcell_be88a2756111d36c79117e00e9d4c2a2" because the technology database is not writable. The candidate via cell will be mapped to regular cell and the references to it instances.
INFO (XSTRM-80075): Via detection cannot use a stdViaDef for "M2_M3pBAR_pcell_e4545bf6d9638fb71364c4b2d4fd805d" due to rounding errors. A customViaDef has been used instead. Use the -dbuPerUU option to increase the DBUperUU to enable detection of stdViaDef.
