- Supports programmable CAS latency
- Supports programmable burst lengths: 2,4 and 8
- Supports write data mask
- Supports the following devices
- Supports up to 1 GB device density
- Supports the following burst types
- Supports burst order
- Supports all mode register programming
- Supports extended mode register programming
- Supports auto refresh & self-refresh modes
- Supports auto precharge option for each burst access
- Supports power down features
- Supports DLL operation
- Checks for following
- Check-points include power up, initialization and power off rules
- State based rules, active Command rules
- Read/Write command rules etc
- All timing violations
- Bus-accurate timing for min, max and typical values
- Notifies the test bench of significant events such as transactions, warnings, timing and protocol violations
