一个primetime annotated的问题

以下是我的大概步骤set power_enable_analysis TRUE
set link_path
read_verilog
link
set_wire_load_model
create_clock
read_sdc
read_vcd ：在这时候，显示
======================================================================
Summary:
Total number of nets = 50237
Number of annotated nets = 50237 (100.00%)
Total number of leaf cells = 33717
Number of fully annotated leaf cells = 33717 (100.00%)
======================================================================
但之后我用
report_annotated_power 显示
|||NOT|
Cell type|Total| Annotated | Annotated |
-----------------------------+-----------+-----------+-----------+
unresolved black-box cell|0|0|0|
leaf cell|33717|0|33717|
-----------------------------+-----------+-----------+-----------+
|33717|0|33717|
所有的cells又都没有被annotated，我的pt_shell version- F-2011.06-SP1
这是咋回事啊。
万分感谢啊

难道上面的是sdf?

用report_power 试试?

确实是sdc，并且report_power之后还是那样。不管咋样谢谢回复哈

我看report_annotated_power这个说明
DESCRIPTION
This command provides a summary report of how many powers are annotated
in the current design and, if the -list_annotated option is specified,
a list of cells with power values annotated on them.
EXAMPLES
The following example shows how power is annotated, removed, and
reported.
pt_shell> set_annotated_power -int 1 -leak 0.01 u0/*
1
pt_shell> report_annotated_power -list_annotated
我需要自己手动设置这个annotated power information吗，还是通过vcd文件它就可以自己找到这个annotated power 信息啊。
