The upper part of the dialog lists some summary information. This information, which is derived from the SPD data, gives a quick indication of the type of device being simulated.

The center section of the dialog lists all 256 bytes of data held in the simulated SPD ROM. The list box provides a description of each byte index in the ROM. If a description is selected, the corresponding data byte is displayed in the text box to the right.

The Import SPD and Export SPD buttons provide the option of loading and saving SPD ROM data. The file format is an unformatted binary image, with an extension of “*.spd”.

The bottom section of the dialog is used to configure DDR PDL Response ranges for the simulated DIMM. PDL response ranges can be individually set for each of 16 PDLs. Adjusting the Low and High value modifies the response range for a particular PDL. When an appropriate response range is set for one PDL, the same range can be applied to all 16 PDLs by clicking on the Match PDLs button. The Reset PDLs button sets all 16 PDL response ranges to their maximum range (0 - 255).

Difference from Real Hardware

The DIMM device does not simulate timing-related issues except for PDL error simulation. The performance of real DIMM hardware is highly dependent on timing and loading issues.

ECC simulation is not provided.
