DDR EyeFinder and EyeScan Software

The DDR EyeFinder and EyeScan

software is a great tool to help you

position the sampling points for accu-

rate read and write data capture. The

software triggers on valid read and

write commands with your system

executing any memory test suite or

stimulus program. The software will

then display read and write data valid

window as a result of the scan.
