DDR4 DETECTIVE FEATURES
- NOW supports 3DS at 3200MT/s!
- Provides logic analyzer like deep transaction Listing and Waveform capture
- Continuous Capture for Violations and Performance metrics NOT a fill memory and then post process like other tools. This is a FuturePlus ONLY feature!
- Eye Detector guarantees valid data acquisition
- Extensive Triggering and Storage Qualification allows precise insight
- Protocol Violation Detector provides hundreds of simultaneous, real time tests to JEDEC specifications
- Margin analysis shows where command timing fails and where it can be improved
- Thousands of counters for DDR4 analyze performance metrics real time, all the time, for all commands, total Clocks, by Rank also power management information
- Interactions among up to 8 ranks, over two slots are analyzed.
- Mode register and SPD capture are provided
- Supports Auto-Clock rate detect and clock stoppage
- Connects to the target under test with DIMM, SO-DIMM, and BGA interposers or a midbus probe
- Integrated Microsoft Charts gives quick insight into large trace captures
- Trigger In & Out allows the Detective to integrate with other test tools

DDR4 Detective Triggering and Store Qualification
Triggering Features
- Full control of Trigger Position from 5% – 95% Post store.
- Adjustable trace depth from 5K to 512M States (1G option available)
- 2 level (Or/Then) address/command triggering. External Trigger In.
- Bit specific trigger set up ability across all A/C/C bus signals and all DDR4 protocol violations
- 3DS support includes Physical Rank and Logical Rank specific triggering
Store Qualification Benefits
- Use any transaction with address as a store qualifier
- Store only certain commands or just violations
- Store only Accesses to a certain bank group/bank/rank

DDR4 test: Protocol Violations
- Covers 65+ tests on all banks and ranks running over 1000 checks continuously and simultaneously
- Automatically calculates protocol parameters based on JEDEC specifications and loads into the protocol checking function
- Allows user to override and enter other parameter values
- Scoreboard display gives quick indication of what test is failing and displays running totals
- Ability to enable and disable each compliance test
- 3DS Specific Violations cover all Physical and Logical Ranks

DDR4 Detective Margin Analysis
- Runs automatically until all parameters are completed
- Measure your memory sub-systems latencies
- Characterize memory latency performance
- Learn what how much margin your system is operating at
- See if ddr4 test coverage is complete

DDR4 Performance Analysis
Real Time, All The Time Continuous Analysis of the DDR4 memory bus.
Competing products capture a miniscule amount of DDR traffic, count the events in the trace and then display. Deadtime between traces and limited trace depths give only a small sampling of actual DDR events. The DDR Detective use new breakthrough architecture to accumulate events on EVERY cycle! Thus no bus events are missed.
This never been done before feature gives unprecedented insight into DDR bus activity for validation, system architects, software engineers and designers.
Bus Command Utilization Analysis – Verify expectations of traffic, show potential hotspots. Choose any DDR4 Command from any bank, bank group or rank.
Page Hit Analysis – Tracks Hits, Misses and Unused for all pages. Viewed by bank, bank groups, or rank.
Bank Group Analysis – Tracks all combinations of Read and Write commands to same and different bank groups.
Power Management Analysis – Follows memory in and out of Power Management states, tracking all related Power Management commands and the total time spent in those states.
Multiple Open Bank Analysis – Reporting open banks allows the user to see how many banks are open simultaneously each second. This isimportant for power consumption as open banks consume power.
Bank Utilization Analysis – Can select by bank or bank groups to show how long an individual bank is open. This is useful in detecting system errors such as excessive activates.
Data bus Utilization Analysis – Bandwidth analysis by bank or rank for all comands affecting the data bus.
Bus Mode Analysis – Useful for tracking system states (Reset, Idle, Active, Precharge PD, Active PD, Max PD, SRX, DLL Dis/Enable, Write Leveling, MPR mode and Vref Training). Can help identify why a system is not booting, or lead to optimization for faster boot times.
Summary/Drill down mode shows hours and even days of results in a single screen
