COVERAGE SELECTIONS
 
Board Cov (Board Coverage): CB
Overall coverage factor can be defined for the board and technology used in this certain step.
For example if you are using inCircuit testing and you have test points in 80% of the nodes, you have Board Coverage 80%. This affects to all coverages you (or tool) enters in three Technology Coverage (Tech Cov) fields (T, P, C).
 
Tech Cov (Technology Coverage): CT, CP and CC
When technology is selected from drop down menu, these fields are filled with default values. You can change the values to ones which better describes capabilities of your test systems.
 
Combining Board Coverage and Tech Coverage
Total defect coverage used in the calculation is product of Board Coverage and Technology Coverages:
- for termination defects: CB x CT
- for placement defects: CB x CP
- for component defects: CB x CC
