How to get STA info base 4_cts.odb

[Pxx-X]

First, I use ORFS run a benchmark successfully, and get 4_cts.odb at results file
Second, I run OpenROAD, and input command read_db 4_cts.odb. I want to do some work base pre-routing info

Question 1
how do I get some STA result like ORFS reports?
I have try some command like report_tns and report_wns, but openroad always return 0, but ORFS output not 0.
If I want to get delay info of all timing path, what should I do?
I try to click Update button of Timing Report and Clock Tree Viewer, but OpenROAD do not return anything. Did I missing some thing to read or load?

Question 2
what infomation of 4_cts.odb file contain? I think .odb = .def + .lib + .lef + .v, is it correct?

the input and output of ORFS is there:aes_cipher_top.zip

Asked by a beginer of EDA, Thank you veryyyyyy much!!

It is better to use the make gui_cts target as that will load the timing data as well.

BTW, when I run ORFS flow, can I stop after CTS done?
Because I don't care the output after CTS, and I find that just commenting the parts of the Makefile of ORFS after cts does not work.
What should I do? Thank you!

BTW2, can OpenROAD TCL terminal use some bash command as Innovus? It will be useful, but I have not find any document describe it.

make cts

We use a standard tcl interpreter so tcl exec ... should work.
