With sophisticated architecture and advanced technology, KNiulink provide DDR4 IP solution with high performance and low power. In advanced process nodes, KNiulink could offer both controller and PHY IPs. In architecture, it supports Multiport AMBA AXI interface, configurable port number and support asynchronous or synchronous AXI port. For PHY interface, it will integrate DFI compatible design. One de-skew PLL is embedded inside the PHY to improve jitter performance.

Deliverables

- Datasheet (Including Integration Guideline, Interface PINs, clock and reset description, all training flows etc.) (DDRMC & DDRPHY)

- Register Map files (register address and function description), timing calculation sheet (DDRMC & DDRPHY)

- Timing lib/db, Layout Frame (.LEF) (DDRPHY)

- Encrypted RTL and Netlist, SPEF/SDF (DDRPHY)

- Top Level GDS (DDRPHY)

- RTL Code & SDC Constraints (DDRMC)

- Verification environment and cases (testbench, DDRIO Verilog model, initial flow, training flow, bandwidth access, DFT pattern
