数字综合—RC，求助标准单元库问题

我用的.18的标准单元库，用RC工具，在对verilog代码综合时候，查看报告（.log文件）文件，里面说：标准单元库里Total cells: '560', Usable cells: '493', Unusable cells: '67'.List of unusable cells: 'ANTENNABWP7T BHDBWP7T CKLHQD1BWP7T CKLHQD2BWP7T CKLHQD4BWP7T CKLHQD6BWP7T CKLHQD8BWP7T CKLNQD1BWP7T CKLNQD2BWP7T CKLNQD4BWP7T CKLNQD6BWP7T CKLNQD8BWP7T DCAP16BWP7T DCAP32BWP7T DCAP4BWP7T DCAP64BWP7T DCAP8BWP7T DCAPBWP7T GAN2D1BWP7T GAN2D2BWP7T GAOI21D1BWP7T GAOI21D2BWP7T GAOI22D1BWP7T GBUFFD1BWP7T GBUFFD2BWP7T GBUFFD3BWP7T GBUFFD8BWP7T GDCAP10BWP7T GDCAP2BWP7T GDCAP3BWP7T GDCAP4BWP7T GDCAPBWP7T GDFCNQD1BWP7T GDFQD1BWP7T GFILL10BWP7T GFILL2BWP7T GFILL3BWP7T GFILL4BWP7T GFILLBWP7T GINVD1BWP7T GINVD2BWP7T GINVD3BWP7T GINVD8BWP7T GMUX2D1BWP7T GMUX2D2BWP7T GMUX2ND1BWP7T GMUX2ND2BWP7T GND2D1BWP7T GND2D2BWP7T GND2D3BWP7T GND3D1BWP7T GND3D2BWP7T GNR2D1BWP7T GNR2D2BWP7T GNR3D1BWP7T GNR3D2BWP7T GOAI21D1BWP7T GOAI21D2BWP7T GOR2D1BWP7T GOR2D2BWP7T GSDFCNQD1BWP7T GTIEHBWP7T GTIELBWP7T GXNR2D1BWP7T GXNR2D2BWP7T GXOR2D1BWP7T GXOR2D2BWP7T .这是什么意思?我看了库里的这些个单元，没发现什么问题。可是报告出这些不可利用，这是什么原因呢?难道给的标准单元库本身就有问题?求大牛开导，本人学生，刚接触数字后端，还望指导！谢谢。

这些cell属于eco cell， 正常flow不用的，
而且0.18的库怎么可能叫bwp7t呢? 感觉不像，
只要没有error到停止的warning就ignore吧， 做完再说

恩，多谢您的指导。我用的单元库的名称就有bwp7t，确实是.18的，工艺库的名称是tcb018gbwp7t。虽然我还不知道ceo cell的使用方法，只要不是critical的warning就行。我就先向后面做了。
多谢，多谢！

哦，tsmc 0.18 7track lib，了解了

这样的库可以在网上下载吗

你可以在论坛上搜一搜，看有没有共享的，一般库都是foundry厂给的。

您好，我也遇到这样的问题，问一下有什么解决办法么?
我是用 memory compiler产生的lib提示我 里面有0个可用单元，1个不可用。
总共就一个SRAM单元，那不可用，可咋办呀
