Providing designers with a suite of automated DDR analysis, visualisation and debug tools, the UniquiPHY DDR System Analyser (DSA) is a comprehensive software package. The analyser complements its adaptive PHY technologies, dynamic self-calibrating logic (DSCL) and dynamic adaptive bit calibration (DABC), by giving the DDR design team a powerful, automated analysis and debug tool that interacts directly with the UniquiPHY DDR PHY.

It allows the user to directly control PHY behaviour and run numerous analyses, including trim and margin tests, DLL step-size tests, and general initialisation and read/write tests.

The streamlined analyses provided by DSA give the DDR design team detailed insight into the DDR system performance and margins and also provide detailed information that speeds DDR system debug.

In addition to specific DDR analyses, DSA provides other useful system-level functions, such as verifying board connectivity and quality such as de-skew. DSA can also be used to help evaluate the performance and quality of different DDR SDRAM components from either different vendors and/or different speed grades.
