Mainstream DFT tools can be separated into 2 groups.
- Test Insertion
- ATPG Tools
Again ranked by popularity
DFT Insertion Tools
- Synopsys DC + TestCompiler (test insertion)
- Mentor DFTAdvisor
- Cadence Encounter RTL Compiler (test insertion features)
- LogicVision DFT
- DeFacTo Technologies
Test Generation Tools
- Mentor FastScan
- Synopsys TetraMax
- Cadence Encounter Test
One could further split the market with tools for Compression, true-time test, BIST, Boundary Scan etc.
