2.1 Config Worksheet

The first worksheet to be configured is the "Config" worksheet, which is divided into two sections. The first section of the worksheet, System Configuration, is where high-level details regarding the custom design would be entered, and more than likely will need customization compared to the default inputs. The second section of the worksheet, Memory Burst Configuration, allows some customization of the read/write burst of the DDR interface. If unsure on how to set the parameters of the Memory Burst Configuration section in the workbook, it is recommended to match the TI default value.
