TurboScan
Advanced Scan Synthesis, Scan Insertion, ATPG, Fault Coverage, and Test Generation
Advanced Scan Technology
TurboScan is an advanced full-scan and partial-scan
test suite. It includes a Scan Synthesizer and an Automatic
Test Pattern Generator (ATPG). TurboScan automatically repairs
testability violations to make your design highly testable.
The ATPG engine uses advanced search and compaction algorithms
to achieve very high fault coverage and produce up to 50%
smaller test pattern size. TurboScan is designed to reduce
product defect level and save test costs.
Features:
 |
Scan Selection and Synthesis - Automatic scan selection
based on your clock domain circuitry. |
 |
Scan Extraction and Debug - Built-in scan extraction
utility recognizes blocks with pre-synthesized scan chains
and incorporates these existing scan chains into the rest
of the design. |
 |
Sequential and Combinational ATPG - Generates highly
optimized test sets for full-scan, partial-scan, and non-scan
designs. TurboScan algorithms work on asynchronous sequential
circuits containing gated clocks, RAMs, ROMs, tri-state
gates, asynchronous set/reset, and unidirectional MOS
transistors. For full-scan designs, sequential ATPG can
be used after combinational ATPG to further improve fault
coverage. |
 |
Very High Fault Coverage - Handles complex design structures
(such as bi-directional pins, transparent latches, bus
contention resolution, rippled sets/resets, bus keepers,
and multiple phase clocks) for DFT to increase fault coverage.
TurboScan supports write and read of memories to allow
surrounding logic to be detected. |
 |
Advanced ATPG search engine - Uses a 32-value system
(compared to the traditional 4-value system) to reduce
the search space during ATPG. This improves the speed
of the ATPG process and further increases the circuit's
fault coverage. |
 |
Extremely Compacted Test Sets - Utilizing dynamic and
static vector compaction to reduce test sets. This reduces
the amount of tester memory needed and shortens the tester
time required, saving your overall test costs. |
 |
Transition and Path-Delay Capability - Supports transition
faults to detect difficult faults such as those at the
tri-state enable pins. TurboScan's timing option generates
test patterns for critical path delay faults and eliminates
false paths from timing analysis. |
 |
Test Generation Modes Supported:
- Full-scan, Partial-scan, or Non-Scan
- Fault Model: Stuck-at, Iddq, Transition, and Path Delay
fault
- Toggle Transition and Toggle State Coverage |
