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??

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？

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?
我們公司現在用的還是國產的老字號 Syntest tool(TurboScan).

另外 MBIST & BSD 應該不是 tool,
MBIST : Memory BIST

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.

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

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

special capability:
Synopsys : support multiple clock domain, phase shift test clock
Mentor   : highest compression
Cadence  : low power handling, pattern fault, diagnostics

Common new features:
Compression, at-speed ATPG, core wrapper, BIST, IEEE1149.1

In my image, Syntest had became a service-oriented company.

我公司也在使用Syntest tool(TurboScan) +1
