2.2.2. Using Custom Memory Timing and I/O Configuration

If you want, you can use custom memory device timing and analog configurations by modifying the values on the Advanced: Memory timing and Advanced Analog: overrides tabs. .

To modify the Advanced: Memory timing and Advanced Analog: overrides values, follow these steps:

  1. In the IP parameter editor, select the Advanced: Memory timing or Advanced Analog: overrides tab.
  2. In the overrides tab, click the + beneath the JEDEC Parameter box.
    Figure 9. Advanced: Memory Timing Tab
  3. Click the parameter that appears in the JEDEC Parameter box. A drop-down menu appears. Select the parameter that you want to change.
    Figure 10. Drop-down Menu
  4. In the list under the values section, search for the parameter you want to change and input the value on the field next to it.
    Figure 11. Modifying an Advanced Memory Timing Value

    If the specified value is not valid for the parameter, an error message appears, listing the valid values.
