DFT 使用工具調查

chip123

為瞭解大家都使用那家公司的工具來做DFT??

) }% {2 h# ]: I! g8 z聽說有人可能用 MBIST 和 BSD？還是比較流行用dc ，但 dc 只是插入scan chain，那 test pattern 用什麼工具呢?TetraMax可以產生test pattern？還是你可能是 Synopsys 的 DFTC、或者 CadenceTetraMAX 兩個都用？

Below is my company DFT releated EDA tools for you reference:
1. dft insertion, Synopsys-dft compiler,
3 n. |. }5 W5 R& U$ s9 t- V2. dft compression, Synopsys-dftMax,
3. mbist, Mentor-mbistarchitect,
4 R1 s  J* {% i! `4. atpg, Synopsys-TetraMax
5. bsd, Synopsys-dftc

我公司也在使用Syntest tool(TurboScan) +1
virtual scan, ac scan 都有用

Cadence ==> RTL Compiler + Encounter Test (acquired from IBM)

Synopsys : support multiple clock domain, phase shift test clock

What's the equivalent gate-counts of your design?

I am a new guy in EDA design area. I want to implement the bsd scan for my design by bsd compiler of synopsys,but I
encountered some difficulty, It made me boring.who can explain the bsd flow in detail.

DFT 包含很廣, 你指的應該是一般常用的 scan chain insertion 及 atpg tool 產品吧?
3 ?5 F% g* W5 k9 Q/ F$ a" n我們公司現在用的還是國產的老字號 Syntest tool(TurboScan).

2 M4 W; g& R! _) h$ aSynopsys : DFTCompiler + TetraMAX
Mentor : DFT Advisor + FastScan
Cadence : ?
Syntest : TurboScan(VirtualScan)

另外 MBIST & BSD 應該不是 tool,
$ i% `5 H, W) U! l3 [4 Y0 M! gMBIST : Memory BIST
BSD : Boundry Scan
