 阶段一
 OverviewIn this workshop you will learn to use DFT Compiler to perform RTL and gate-level DFT checks and insert scan using top-down and bottom-up flows. The workshop will show you how to analyze the reported data to identify common DFT violations and then fix the original RTL design.?
 
 The workshop explores essential techniques to support large, multi-million gate SOC designs including the bottom-up scan insertion flow in the logical (Design Compiler) domain. Techniques learned include: performing scan insertion in a top-down flow; meeting scan requirements for number of scan chains, maximum chain length and reusing functional pins for scan testing; and using Adaptive Scan (DFTMAX) to insert additional DFT hardware to reduce the test time and the test data volume required for a given fault coverage.?
 ? Objectives?At the end of this workshop the student should be able to:?
 Define the test protocol for a design and customize the initialization sequence, if needed?
 Perform DFT checks at both the RTL and gate-levels?
 State common design constructs that cause typical DFT violations?
 Automatically correct certain DFT violations at the gate-level using AutoFix.?
 Insert scan to achieve well-balanced top-level scan chains and other scan design requirements?
 Write a script to perform all the steps in the DFT flow, including exporting all the required files for ATPG and Place & Route.?
 Implement Rapid Scan Synthesis (RSS) in a top-down scan insertion flow achieving well-balanced scan chains?
 Modify a bottom-up scan insertion script for full gate-level designs to use Test Models/ILMs with RSS and run it?
 Preview top-level chain balance using test models/ILMs after block-level scan insertion and revise block level scan architecture as needed to improve top level scan chain balance.?
 Modify a scan insertion script to include DFT-MAX Adaptive Scan compression?
 Configure DFT Compiler to support low power flows including clock gating and multivoltage?
 Audience ProfileDesign and Test engineers who need to check for, identify and fix design-for-test violations in their RTL?or?gate-level designs, insert scan into possibly multi-million gate ASICs, and export design files to ATPG and Place&Route tools.
