11.2.2. Vendor Memory Model
Contact the memory vendor directly, because many additional models are available from the vendor's support system.
When using memory vendor models, ensure that the model is correctly defined for the following characteristics:
- Speed grade
- Organization
- Memory allocation
- Maximum memory usage
- Number of ranks on a DIMM
- Buffering on the DIMM
- ECC
Note: Refer to the readme.txt file supplied with the memory vendor model, for more information about how to define this information for your configuration. Also refer to Transcript Window messages, for more information.
Note: Intel® does not provide support for vendor-specific memory models.
During simulation vendor models output a wealth of information regarding any device violations that may occur because of incorrectly parameterized IP.
