想用 dft_drc -coverage_estimation 看一下覆盖率，但是最后报错dead socket，大家遇到过这种情况吗？
报错信息如下：

SEQUENTIAL CELLS WITH VIOLATIONS
   * 5 cells have test design rule violations
SEQUENTIAL CELLS WITHOUT VIOLATIONS
   *28611 cells are valid scan cells

Information: Test design rule checking completed. (TEST-123)
  Running test coverage estimation...
Error: dead socket.
Error : Could not get fault coverage information.
Error: Could not perform design rule checking. (TEST-1311)
