GDDR7 memory controller
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 3
GDDR7 SGRAM controller for PAM3 signalling with four channels per device, on-die and link ECC handling, data poisoning and retry.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
