LPDDR4 DETECTIVE FEATURES
- Provides logic analyzer like deep transaction Listing and Waveform capture
- Can store up to 1G of captured States at up to 3200MT/s
- Continuous, real time analysis, not post-processing
- 2D (voltage & time) Eye Detector guarantees valid data acquisition on each signal
- Extensive Triggering and Storage Qualification allows precise insight
- Protocol Violation Detector provides hundreds of simultaneous, real time tests to JEDEC specifications
- Mode Register Listing provided
- Supports Auto-Clock rate detect and clock stoppage
- Connects to the target under test with Flying Lead, 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
LPDDR4 Detective Set-up
- Easy Setup Guide steps the user through the process
- DDR Detective automated setup calibrates to your target and bus speed in 90 seconds. This allows for use in marginal systems
- Several CK operating points are supported automatically
- Final MRS values are automatically loaded into protocol analysis tools.
LPDDR4 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
- No need to define 4 states for a Command trigger, the Detective has them pre-defined.
- External Trigger In and Out
- Bit specific trigger set up ability across all A/C/C Commands and bus signals or LPDDR4 protocol violations
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
LPDDR4 Detective Protocol Violations
- Covers over 60 tests on all banks and ranks running over 1000 checks continuously and simultaneously. You never miss a clock cycle.
- 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
LPDDR4 Detective Performance Counters
Use real time counters to track multiple performance metrics:
- Command and Data Bus utilization
- Power management
LPDDR4 Detective Probing
All 4 technologies DDR3, DDR4, LPDDR3 and LPDDR4 in one box with interchangeable probing choices!
- SODIMM Interposer – DDR4 and DDR3, also LPDDR4 on module
- BGA Interposer – various package formats for DDR4, DDR3, LPDDR4 and LPDDR3 – Contact us
- Flying Lead – High speed coax wire solderable to pcb features
- Mid-bus Connector-less probing – Industry standard “Soft-Touch Pro” compatible
The DDR Detective® gives the phrase ‘cost effective’ new meaning!
LPDDR4 on DDR4 SODIMM Interposer:
- JEDEC Compliant 260 pin
- Operation up to 3200MT/s
- Interposer design saves a slot
- Rigid/flex design allows for use in both RVS and STD connectors.
- All signals are probed passively
- Electrically extends the bus approximately 2.0 inch
- 72 bit operation supported
- Simultaneous connection to Keysight Logic Analyzer available
BGA Interposer:
- Quick and easy connection to most Keysight logic analyzer Chip Interposers
- Scope Interposers can be used with Flying lead cable
- Contact us on package requirements
Flying Lead cable:
- Quick and easy connection to Keysight Scope Chip Interposers
- Can also be soldered to pcb features
- 38 AWG wire
Mid-Bus Probe:
- Single, dual and 3-head configuration available
- Midbus probing is ideal for embedded applications where no DIMM or SODIMM slot is present
- Connector-less midbus footprint can remain as part of the design throughout product life for service
