GDDR4 Synthesizable Transactor provides a smart way to verify the GDDR4 component of a SOC or a ASIC in Emulator or FPGA platform. The SmartDV's GDDR4 Synthesizable Transactor is fully compliant with standard GDDR4Spec rev 04.pdf Specification and provides the following features.
- Features
-
- Supports 100% of GDDR4 protocol standard GDDR4Spec rev 04
- Supports all the GDDR4 commands as per the specs
- Supports all types of timing and protocol violation detection
- Supports all mode registers programming
- Supports double data rate architecture
- Supports programmable clock frequency of operation
- Supports single ended read strobe (RDQS) per byte
- Supports single ended write strobe (WDQS) per byte
- Supports quad or eight internal banks for concurrent operation
- Checks for following:
- Check-points include power on, initialization and power off rules
- State based rules, active command rules
- Read/write command rules etc
- All timing violations
- Supports programmable burst length: 8 only
- Supports data mask (DM) for masking write data
- Supports multiplexed addressing
- Supports auto precharge option for each burst access
- Supports auto refresh and self refresh modes
- Supports on‐die termination (ODT)
- Supports programmable offset for both driver and termination
- Supports parity and boundary scan
- Notifies the test bench of significant events such as transactions, warnings, timing and protocol violations
- Benefits
-
- Compatible with testbench writing using SmartDV's VIP
- All UVM sequences/testcases written with VIP can be reused
- Runs in every major emulators environment
- Runs in custom FPGA platforms
