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.

  • Hi Bob,

    Thanks for the reply.

    I tried your solution and I have few questions on it. 

    encounter 6> get_property -view func_worst [get_pins pc0/vreg_ovp_reg_0/CKN] clocks

    0x11692
    encounter 7> get_property -view test_worst [get_pins pc0/vreg_ovp_reg_0/CKN] clocks

    0x11694
     

    I did not get clock name as in your case.

    I tried the looping through the registers using your foreach loop and replacing correponding views and clock name.  For hierarchical_name i am assuming, i have to replace it with any instance name. This is what i had, but could not get it to run correctly.

    foreach_in_collection register [all_registers] {
      foreach_in_collection pin [filter_collection [get_pins [get_property $register pc0]/*] {is_clock == true}] {
        set clk [get_property [get_property -view func_worst $pin clocks] pc0]
        if {$clk == "CLK5"} {
          Puts "Pin: [get_property $pin pc0] in view \"func_worst\" is driven by \"CLK5\""
        }
      }
    }

    When you have set clk[get_property...], the inner get_property gets the pins but what about the outer get_property? which property is it trying to fetch?
