Differential input/output check
■Validation pattern name
FNA_TOP_01010102
■Purpose
To perform inversion control and output control for the differential input of differential input/output circuit boards, and to check
that it is output to the differential output of the differential input/output circuit boards
■Check item
Perform inversion control and output control for the differential input of differential input/output circuit boards, and check that it
is output to the differential output of the differential input/output circuit boards. (Check the above for each of circuit boards B0,
B1, B2, E0, E1, and E2)
■Procedure
Configuration: B0 to B2 differential input/output circuit boards and E0 to E2 differential input/output circuit boards, without
verification model connection of DDR3L SDRAM
1.
Reset the sequence.
2.
Set the register areas for B0 to B2 differential input/output circuit boards and E0 to E2 differential input/output circuit
boards. Also, set the related register areas as shown in the table below.
