Everything you need to configure, verify and tune DDR

VTOS DDR is a low-cost software product that provides everything you need to configure, verify, and tune the DDR memory of your board design.

VTOS DDR is a standalone DDR verification tool that also integrates with Kozio's vAccess for automated production test.

VTOS DDRis sold as multiple products:

  • VTOS DDR Test - for comprehensive DDR 2/3/4 testing.
  • VTOS DDR Tune - for comprehensive DDR 2/3/4 optimization and testing.


VTOS DDR Provides

  • Object files that are ready-to-run on your embedded device using a supported processor.
  • On-the-fly DDR configuration for DDR2, DDR3, DDR4, and mDDR (LPDDR) memory controllers.
  • A rich suite of directed memory tests that verify the entire 64-bit DDR memory range, including address testing, burst testing, noise testing, and stress testing.
  • Constrained random capabilities for extended memory testing and burn-in.
  • A powerful scripting environment for automated tuning of DDR settings, all at full processor speed.
  • Test reports that can be exported to spreadsheets for further analysis.
  • Highly optimized test algorithms that make it possible to test every cell of memory in production.
