check_library cells missing in logic library

lilyzhong

check_library的时候出现下面提示Number of cells missing in logic library:       12 (out of 664)
在后面的过程中就会出现好几处warning
The 'A2LVLD_X2_A7TULL' cell in the '/home/xxx' physical library does not have corresponding logical cell description.

The 'A2LVLD_X8_A7TULL' cell in the '/home/xxx' physical library does not have corresponding logical cell description.
这两个是常出现的
不过DC和ICC都可以继续跑下去


有看到说是physical only cells，可以不用管
但是man的时候，显示
This  message  is  for  reporting missing cells in logic library during logic vs. physical library checking.  All  the  physical  cells  except physical  only cells that are missing in logic library will be reported in this table.
对于physical  only cells会专门显示
This  message  is  for  reporting  physical-only  cells in the physical library.


谢谢
