What is the best tool out there for DFT?

Can cadence buildgates synthesis tool do DFT? What about synopsys DC??

Which is the best tool out there for DFT? Does synopsys offer anything?

hi, i think there are more customer for dft compiler in dc.
ambit can do dft things, blast create of magma also.

Re: DFT tool

Mentor DFTAdivisor and FastScan gain much popular .

dft adviser is dft tool. but fastscan is atpg tool, not for dft. they are different.

Re: DFT tool

Test Compiler is build in DFT tool in synopsys DC.

DFT Compiler (DC Synopsys) is popular in scan chain insertion process and FastScan (Mentor) is the same in test pattern generation process

Re: DFT tool

Cadence's Buildgates/PKS offers full scan-insertion and (if you have a PKS license), "placement-aware" scan-chain re-ordering. Having used both Ambit-DFT and Synopsys's DFT-compiler, I have to say DFT-compiler is easier to use. It's also more tightly coupled with Synopsys' TetraMAX (ATPG) companion tool (which my employer uses.)..

> Test Compiler is build in DFT tool in synopsys DC.

To clarify, Synopsys Test Compiler requires a Test-Compiler license. It is not 'free', as Synopsys still sells standalone Design_Compiler licenses. The program executable is packed in the same CD-image on Solvnet, but then so is Physical Compiler, DC-Ultra, Designware Foundation, and a bunch of other *expensive* add-on products.

I can't speak for the other tools, but Ambit-DFT is included free with Buildgates (no separate license needed.) If you have access to Ambit-DFT, you may as well give it a try. If your project is "DFT-clean", then Ambit is painless to use and will get the job done. On the other hand, if your project is not DFT-clean (lots of asynchronous set/reset flipflops, clocks not accessible from a primary-port, lots of custom 'macros', etc.) -- you will share my pain and find yourself making many RTL-code changes to accomodate Ambit-DFT.

dc can do it, please read the dc manual

DC and magma are all powerful!!

Re: DFT tool

You can do initial level scan in Ambit.

synopsys' DFT complier can do some jobs of this, but i am still wondering how powerful DFT compiler is.

can it bypass macros, or mux gated clocks and set/reset automatically??

Re: DFT tool

cadence ambit do scan chain insertion and test rule check.but didnot do wrapper on memory .
I recommended SYNTEST dft tools which can do same as ambit but with a cheap price.

I can do dft using DC

Re: DFT tool

now we are using Synopsys tools dft compiler, need a sperate license from design compiler, it do well job for scan test

Re: DFT tool

hi
use dftAdvisor and FastScan from mentor

Re: DFT tool

Maybe refer to the following survey:
https://www.deepchip.com/items/snug05-10.html
-----------------------------------------------------------------
Subject: Synopsys DFT Compiler/TetraMAX vs. Mentor DFT Advisor/FastScan

Synopsys DFT Compiler: ########################### 68%
Mentor DFT Advisor: ############# 32%

Synopsys TetraMAX: ####################### 57%
Mentor FastScan: ################# 43%

And Cadence Test Encounter came in at 4%, but that's not a fair number since
I forgot to mention them by name in the question.

Re: DFT tool

Dftadvisor and fastscan by mentor graphics . the new version dftvisualizer is too good
