Validation Test for IC Digital Design

  1. 1. Validation Test for IC Digital Design Alex Lollio, Global Rotation Engineer Automotive Products Business Unit Provence Design Centre, France Sept, 2013 - Oct, 2013 Project Leader : Denis Parmentier Project Manager : Andre Mourrier Program Mentor : Massimo Grasso COMPANY CONFIDENTIAL 1
  2. 2. Digital Design Flow: Validation Test is missing 1. CADENCE DIGITAL SIMULATION TEST Digital Pattern Testing Signal 2. SIMULATED DUT Expected Output VALIDATION TEST CADENCE “.stil” file generation VALIDATION TEST ON DIGITAL DESIGN IS MISSING 3. FAILURE ANALISYS Digital Pattern Testing Signal Real DUT Output REAL DUT COMPANY CONFIDENTIAL
  3. 3. Digital Design Flow: Proposed Validation Test 1. CADENCE DIGITAL SIMULATION TEST Digital Pattern Testing Signal 2. SIMULATED DUT Expected Output PROPOSED VALIDATION TEST Digital Pattern Testing Signal Real DUT Output REAL DUT PXI System located in Provence Test Passed if Real DUT Output = Expected Output COMPANY CONFIDENTIAL
  4. 4. Project Goal: Testing Application Digital Pattern Testing Signal 0$ 2k$ DUT CADENCE “.stil” file generation TSSI Converter “.stil” to “.xml” 0$ CADENCE SIMULATION Expected Output PROPOSED VALIDATION TEST 7k$ ? DUT LabVIEW application for Generating and Acquiring the digital data and make the comparison test Project Goal: Write LabVIEW application for making the test COMPANY CONFIDENTIAL
  5. 5. PXI System Overview BANANA TERMINALS PXI CHASSIS HSDIO (NI PXI-6552) • -2 to 5.5V DIO Channels • Clock 100MHz • Internal Memory 8MB PXI CONTROLLER COMPANY CONFIDENTIAL
  6. 6. Real Test Bench located at IR Provence COMPANY CONFIDENTIAL
  7. 7. LabVIEW Interface: Signal Gen&Acq COMPANY CONFIDENTIAL
  8. 8. Conclusions • LabVIEW Application for .STIL Digital Testing has been presented • The LabVIEW Application Source Code has been uploaded to Provence Server and can be easily modified by everyone • LabVIEW Classes of 5 working days has been done in Provence Design Center • PXI system can be easily upgraded with an analog card in order to synchronize digital generation with analog acquisition • Next step is to add to the system the IDDQ testing capability COMPANY CONFIDENTIAL
