GENUS加载工艺库后报Warning

GENUS191加载工艺库后报多个类似Warning：


Warning : Detected both combinational and sequential timing arcs in a library cell. This might prevent the tool from using this cell for technology mapping. The tool will treat it as unusable. [LBR-76]
        : The arc 'CK_E_Ha0' between pins 'CK' and 'E' in libcell 'TLATNCAX12' is a sequential timing arc.
        : The library cell will be treated as a timing-model. Make sure that the timing arcs and output function are defined correctly. Even if the cell intends to have dual-functionality, it cannot be unmapped or automatically inferred.

TLATNCAX12是时钟门控单元，是否GENUS191不支持这种结构？Warning说不能自动推断出该单元，那么是否可以直接实例化？
