How to report list of flops whose clock port is driven by test clock in test mode

diablo

 Hi all,

  I have functional and test analysis views. The Test clock is muxed with functional clock whose selector is TEST_EN net.

  In my functional SDC, I have "set_case_analysis 0 TEST_EN" and in test SDC, I have "set_case_analysis 1 TEST_EN". I want to verify  whether in test analysis view, the Test clock is seen by all the flops. 

  How to report the list of flops whose clock port is driven by test clock in test analysis view.

 Thanks for your time.

  • Hmm - that's strange that it appears to be returning a collection, but the name of the clock isn't echoed.

    "get_proeprty [get_pins xxx] clocks" should get a collection of clocks.  To query the name of those clocks we need to:

    get_property [get_property -view func_worst [get_pins pc0/vreg_ovp_reg_0/CKN] clocks] hierarchical_name

    -or- if there are multiple clocks you could iterate through each like this:

    foreach_in_collection clk [get_property -view func_worst [get_pins pc0/vreg_ovp_reg_0/CKN] clocks] {puts "[get_property $clk hierarchical_name]"}

    "hierarchical_name" is an attribute off clocks and other objects alike so you shouldn't have to swap out hierarchical_name for instance_name.  The outer get_property returns the name, the inner get_property returns a collection.

    Let us know how these suggests enlighten things and we can go from there.
