4 Test Head Filling and DUT Board Considerations Test System Configuration

72 System Reference, January 2001

There is a filling algorithm for filling the test head with

digital boards and analog modules:

• Digital Filling:

Group 1 ---> Group 2 ---> Group 3 ---> (Group 8)

• Analog Filling:

(Group 8) only

The bracket indicates that group 8 can optionally be used

for digital or analog testing. For this reason you can find it

under both list items.

This system configuration has the following maximum

analog and maximum digital configuration:

• Maximum Analog:

8 analog modules ---> 384 digital pins

• Maximum Digital:

no analog modules ---> 512 digital pins

The main advantage of the digital dominant configura-

tion of the 512 pin tester compared to the analog domi-

nant type of the 512 pin tester is that digital is populated

in the groups on the bottom line of the DUT board as well

as in the upper line groups. This makes DUT board routing

for digital signals much simpler.

2. The reservation of groups of the digital dominant type of

the 1024 pin SOC series tester are illustrated in Figure 36.
