A problem about Conformal

Hi all,

I am writing a do file with Encounter Conformal Verify to check clock domain cross. In this module, there are two clocks, however some ports belong to none of these two clocks but belong to another clock in another module.

The do file is as below:

elaborate design -root d_ip_llwu_syn 

add clock 1 -waveform 1 1 2 ipg_clk_ips2dgo//????
add clock 1 -waveform 1 1 2 ipg_clk_3v
add clock 1 -waveform 1 1 2 ipg_clk_s_3v
 

The ipg_clk_ips2dgo does not appears in d_ip_llwu_syn, but in d_ip_ips2dgo_syn. As I add ipg_clk_ips2dgo, run the dofile, it says ipg_clk_ips2dgo is not a primary input. Of course it is not ^ ^

How can I add another clock in the dofile, while it is not in the exact module?

Thanks in advance.
