WIDTH = 8 - The size of memory in wordsĪDDRESS_RADIX = HEX - The radix for address valuesĭATA_RADIX = BIN - The radix for data valuesĬONTENT - start of (address : data pairs) A Sample MIF File will have the following shape DEPTH = 32 - The size of data in bits The MIF format will be nothing but a lookup table that specifies the address of each pixel and the alias of each color using the RGB Color code. In order to display a BMP image onto a monitor using the built-in VGA connections, I must first transform the BMP image into its MIF Format. Note: The Quartus II software searches for the altsyncram init_file in the project directory, the project dbĭirectory, user libraries, and the current source file location.I am working on the DE12-115 microprocessor from Altera using Quartus. The content that is initialized to ‘X’ is shown only when you perform the read operation.

ForĮxample, if your target memory block is M4K, the output is cleared during power-up (based on Table 4–Ĩ). This option does not change the power-up behavior of the RAM but initializes the content to ‘X’. To initialize theĬontent to ‘X’, turn on Initialize memory content data to XX.X on power-up in simulation. To initialize the memory to zero, select No, leave it blank. You can include the files using the parameter editor when (.mif) or Hexadecimal (Intel-format) file (.hex). To identify the type of memory block the software selects to implement your memory, refer to theĪll memory blocks (excluding M-RAM) support memory initialization via the Memory Initialization File Note: When the memory block type is set to Auto in the parameter editor, the compiler is free to chooseĪny memory block type, in which the power-up value depends on the chosen memory block type. Used, MLAB blocks power-up to read the memory contents while M-RAM blocks power-up to an MLAB and M-RAM blocks power-up to zero only if output registers are used. Load the contents of the memory block, the output is still cleared. Even if a memory initialization file is used to pre. Of whether the output registers are used or bypassed.

The outputs of M512, M4K, M9K, M144K, M10K, and M20K blocks always power-up to zero, regardless Outputs cleared if registered, otherwise reads memory Outputs cleared if registered, otherwise unknown This table lists the power-up conditions in the various types of embedded memory blocks. Table 3-10: Power-Up Conditions for Various Embedded Memory Blocks Power-up conditions depend on the type of embedded memory blocks in use and whether or not the Power-Up Conditions and Memory Initialization Memory block being used, provided you do not assign block type when you instantiate the memory
