执行picxo v2.6 pre_opt.tcl期间的严重警告

嗨，当我使用picxo（v2.6）时，它有一些严重警告。我没有限制picxo; Dosethese警告影响了picxo的工作？
笔记：vivado 2016.1
pre_opt.tcl：
[vivado 12-3346]无法在实例U_xx / U_xx / U_xx / PICXO_FRACXO_0_i / U0 / inst_picxo_top / obsawdkjh4ob / obsaiuran4bscm4fvcd上打印'LOCK_PINS'。
该单元格位于SLICE_X354Y120。
该单元格已具有“LOCK_PINS”属性。
请在取消新单元格之前取消单元格并重置属性。[lin：636]
