想把gds导入virtuoso中，看版图，如果可以过lvs和drc的话，打算直接调用。

报的是类似的错误，警告中的其中2条代表是：

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.

这是什么原因呢？是工艺库的只读权限吗？
我听有些大佬说报警告不用管，只要不报error就行。
