GDDR6 DFI Synthesizable Transactor

GDDR6 DFI Synthesizable Transactor provides a smart way to verify the GDDR6 DFI component of a SOC or a ASIC in Emulator or FPGA platform. The SmartDV's GDDR6 DFI Synthesizable Transactor is fully compliant with standard DFI version 4.0 or 5.0 Specifications and provides the following features.

• Compliant with DFI version 4.0 or 5.0 Specifications.
• Supports GDDR6 devices compliant with JEDEC GDDR6 SGRAM Standard JESD250A and JESD250B.
• Supports GDDR6 x16 or x8 clamshell modes.
• Can be configured as a single controller driving two x16 GDDR6 channels simultaneously (x32 total) or two controllers each driving one x16 GDDR6 channel.
• Supports GDDR6 operation at up to 18Gbps.
• Supports GDDR6 error detection code (EDC).
• Supports controller retries read and write transactions after EDC error detected.
• Supports GDDR6 data bus inversion (DBI) and CA bus inversion (CABI).
• Supports Per-bank and All-bank refresh.
