7.1.4. Intel Cyclone 10 GX EMIF IP LPDDR3 Parameters: FPGA I/O
You should use Hyperlynx* or similar simulators to determine the best settings for your board. Refer to the EMIF Simulation Guidance wiki page for additional information.
Display Name | Description |
---|---|
Voltage | The voltage level for the I/O pins driving the signals between the memory device and the FPGA memory interface. (Identifier: PHY_LPDDR3_IO_VOLTAGE) |
Use default I/O settings | Specifies that a legal set of I/O settings are automatically selected. The default I/O settings are not necessarily optimized for a specific board. To achieve optimal signal integrity, perform I/O simulations with IBIS models and enter the I/O settings manually, based on simulation results. (Identifier: PHY_LPDDR3_DEFAULT_IO) |
Display Name | Description |
---|---|
I/O standard | Specifies the I/O electrical standard for the address/command pins of the memory interface. The selected I/O standard configures the circuit within the I/O buffer to match the industry standard. (Identifier: PHY_LPDDR3_USER_AC_IO_STD_ENUM) |
Output mode | This parameter allows you to change the current drive strength or termination settings for the selected I/O standard. Perform board simulation with IBIS models to determine the best settings for your design. (Identifier: PHY_LPDDR3_USER_AC_MODE_ENUM) |
Slew rate | Specifies the slew rate of the address/command output pins. The slew rate (or edge rate) describes how quickly the signal can transition, measured in voltage per unit time. Perform board simulations to determine the slew rate that provides the best eye opening for the address and command signals. (Identifier: PHY_LPDDR3_USER_AC_SLEW_RATE_ENUM) |
Display Name | Description |
---|---|
I/O standard | Specifies the I/O electrical standard for the memory clock pins. The selected I/O standard configures the circuit within the I/O buffer to match the industry standard. (Identifier: PHY_LPDDR3_USER_CK_IO_STD_ENUM) |
Output mode | This parameter allows you to change the current drive strength or termination settings for the selected I/O standard. Perform board simulation with IBIS models to determine the best settings for your design. (Identifier: PHY_LPDDR3_USER_CK_MODE_ENUM) |
Slew rate | Specifies the slew rate of the address/command output pins. The slew rate (or edge rate) describes how quickly the signal can transition, measured in voltage per unit time.
