The General tab contains top-level options for configuring the DDR subsystem, as shown in Figure 1. The fields available on this tab are:
- Clock—to set the DDR memory clock frequency and user logic clock rate. The user clock frequency is automatically populated.
- Topology—to set the topology of the memory system, including the address bits, bank configurations, DM modes, and ECC.
- Memory Format—to select component or type of DIMM.
- Enable Parity/Alert—when the memory format is RDIMM or LRDIMM, this option can be selected to support the Alert signal from DDR memory when it detects a CA parity error.
