Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
LPM_WIDTH |
Integer | Yes | Width of the q[] port. |
LPM_WIDTHAD |
Integer | Yes | Width of the address[] port. LPM_WIDTHAD should be (but is not required to be) equal to LOG2(LPM_NUMWORDS). If LPM_WIDTHAD is too small, some memory locations are not addressable. If it is too large, the addresses that are too high return undefined logic levels. |
LPM_NUMWORDS |
Integer | No | Number of words stored in memory. In general, this value should be (but is not required to be) 2 ^ LPM_WIDTHAD-1 < LPM_NUMWORDS <= 2 ^ LPM_WIDTHAD. If omitted, the default is 2 ^ LPM_WIDTHAD. |
LPM_FILE |
String | Yes | Name of the Memory Initialization File (.mif) Definition or Hexadecimal (Intel-Format) Output File (.hexout) Definition containing ROM initialization data ("<file name>"), or "UNUSED". |
LPM_ADDRESS_CONTROL |
String | No | Values are "REGISTERED", "UNREGISTERED", and "UNUSED". Indicates whether the address port is registered. If omitted, the default is "REGISTERED". |
LPM_OUTDATA |
String | No | Values are "REGISTERED", "UNREGISTERED", and "UNUSED". Indicates whether the q and eq ports are registered. If omitted, the default is "REGISTERED". |
