HBM4 PHY
Maturity plannedTargets ASIC (CMOS) onlyDifficulty Very hardPriority 2
HBM4 PHY for the 2048-bit interface with 32 channels, intended for logic base dies and advanced packages.
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.
