DFT and DFM meaning???

[imar]

hello freinds!
can any one help me and give me some explanation or links about :
*DFM: Design For Manufacturing
* DFT: Design For Testability.

thanks in advance!

DFM: its more related to layout and less related to Circuit Design , but while designing Circuit itself we can consider DFM Issues also....

DFT: it is different from DFM ...it purely related to testing

thanks ninge!
is there any book of tutorial that may help to have a deep knowlege in that field. it seems nice to practice this kind of work either when designing or when achieving Layout. i want to have more information about it?

thanks for your help.

You've got hundreds of Application notes on the web otherwise.

DFM purpose is to help a given design to be manufactured in volume with maximum yield. Design for Manufacturing = improve robustness versus defectivity and process window.

DFM Principles

1/ Do not use min rules when not necessary
– Find best compromise between all recommendations
– Pay specific attention to repetitive cells
( i.e., lot of instances per product like standard cells and some sub-circuits in
memories …)
– Take care of critical signals
(noise, timings, matching …)
– Most of the gain comes out from small improvements
2/Target homogeneous density for each layer
3/And for all of these, do not increase chip or cell area
