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
