Problem with the Coverage Analyst

Hello,

I have a problem with the Coverage Analyst.

I am using the Coverage Analyst version 5.21p. The Coverage Analyst finishes the coverage report ok (html files), but i have a problem with the results shown in the report:
- Coverage Analyst shows that some devices (Resistors) do not have any test associated with them, so as, the html report-page of each device shows "Number of tests = 0".
But:
- Each one of these resistors have their own object file in the "analog" folder, and they are tested ok with the ICT.
- These resistors have the properties "placed" and "testable" in the file "board.o", and they are included in the "testorder" and "testplan" files.
So, the question is:

Why the Coverage Analyst does not show that these resistors are tested?, What can be wrong?

Thanks in advance for your help.

No one else has this question

Hi jmvicent,
May I know which category are the resistors found in the board file?
Are they under the RESISTOR category or in PIN LIBRARY?

Would you like to send us the test directory?
This will allow us to determine the reason for this.

Please send to adrian_cheong@agilent.com

Thanks ... adrian

Hi adrianc,

the resistors are under the RESISTOR category.

I am sorry, but i can't send you the test directory.

Thanks,.

Is this the only test directory that is exhibiting this symptom?

Hi,

Yes, this is the only test directory with this problem.

Hi jmvicent,
"Coverage Analyst shows that some devices (Resistors) do not have any test associated with them"
>> are all the resistors missing in the Coverage Analyst report? or just some?

For those resistors that are missing in the Coverage Analyst report, choose one example.
- the resistor test file in the analog directory, is the resistor test statement commented?
   e.g.   !resistor 909, 1.32, 1.17, re2, ar20.0m, ed, sa, sb, sl, en
   Can you send me one of the resistor test source file?

- the testorder file includes the resistor test. Which of the below statements is found in the testorder
e.g.   test resistor "r121"; nulltest
           test resistor "r120"; comment
           test resistor "r122"

- the testplan file includes the resistor test. What test section is the test located in? Please send me a copy of the test subroutine that the test is found in.
e.g.   sub Analog_Tests

- again in the testplan, is the subroutine called in the "sub Test_Sections" subroutine?
   e.g.   call Analog_Tests (Failed_In_Analog, Mode$ & AnalogMsg$)

Thanks.

Hi adrianc,

Coverage Analyst has missed some resistors (not all of them).

For those missed resistors:

- The test statement inside the test file on the analog directory is not commented.

- The testorder includes these resistors, i.e.:
           test resistor "r6"
           test resistor "r7"
           test resistor "r8"

- Resistors tests are included in the Analog_Tests subroutine. See below the "call":

       if Logging or not learning then
            call Analog_Tests (Failed_In_Analog, Mode$ & AnalogMsg$)
            if boardfailed then subexit
       end if

* I will send you an email with some resistor tests source files and the Analog_Tests subroutine from the testplan.

Thanks, Jose
