Testable Modifications & Fault Coverage Prediction

with your primary Netlist before DFT Modifications made

with your secondary Netlist met our advices after DFT Modifications made

We fulfil thorough testability analysis of every bit which is the value "0" or "1" assigned to any node of your circuit. We calculate two measures per bit (controlability-brown & observability - blue). We show two histograms of distribution of brown & blue measures upon levels from zero to the worse measure of the maximum value.

График тестопригодности

better==>worse brown distribution on controlability - how straitened to reach bit from inputs
worse <==better blue distribution on observability - how straitened to transport bit onto any output
dashed lines show thresholds below which ATPG still possible thereof measures are good
fault coverage prediction based upon the testable area surrounded by bright red line where both controlability & observability measures are good thereof ATPG is possible
in other words testable area or testability is possibility of ATPG

The high quality test should be generated

If testability is bad we offer advices to customer how to improve for circuit testability by inserting testable modifications.
