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
