create_generated_clock works?

 I am trying to analyze timing relationship between output clock and output data.  I set up the following in RTL compiler.

dc::create_generated_clock  -name clock_out -source clock_src -divide_by 1 [dc::get_ports clock_out]

dc::set_output_delay -clock clock_out 2 {data_out}

These commands are generated correctly in SDC file, I pass this onto Encounter for P&R for final timing analysis only.  I generate timing report as following (simplified below):

report_timing -clock_to clock_out

When I look at the report, it does not show any propagated delay from clock_src and clock_out is treated as ideal clock.  I have done similar setup with Primetime and it correctly analyzed timing relationship between clock_out and data_out.

I appreciate help.  Thanks!
