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
