Using the Memory Generator Wizard (for Block Memory) - 2022.2 English

1. Open the Memory Generator wizard using one of the following methods:

   On the Logic Sheet, click Add Memory.

   
   
   
   
   

   OR

   On the IP Manager Sheet, click Manage IP.

   
   
   
   
   
   1. In the IP Manager dialog box, click Create IP.
   2. In the dialog box IP catalog, select Block Memory.
   3. In the dialog box, click Create.
2. In the Block Memory tab of the XPE Memory Generator dialog box, fill out the information in the dialog box for one block memory Memory Type in your design.
   
   

   The fields in the Block Memory tab are:

   Memory Type

   Select the type of memory your design will use.

   • Single Port RAM
   • Simple Dual Port RAM
   • Single Port ROM
   • Dual Port ROM

   Clock

   Enter the clock frequency at which the distributed memory will operate. For dual-port memory types, XPE assumes the same clock frequency for both Port A and Port B.

   Algorithm

   Specify which of these algorithms the Xilinx design tools will use to configure block RAM primitives and connect them together:

   Minimum Area

   The memory is generated using the minimum number of block RAM primitives.

   Low Power

   The memory is generated such that the minimum number of block RAM primitives are enabled during a Read or Write operation.

   Toggle

   Enter the average toggle rate of the data signals. A toggle rate of 50% means that half of the data signals toggle each clock cycle.

   Port A and Port B

   If you have selected a single port Memory Type, you will enter information for Port A only. If you have selected a dual port Memory Type, you will enter information for both Port A and Port B.

   Width

   Enter the bit width for each word in the port.

   Depth

   Enter the depth of the port . Width × Depth is the total number of bits in the memory.

   Enable

   Enter the percentage of time that the port will be enabled.

   Mode

   Select the operating mode for the block RAM: READ_FIRST, WRITE_FIRST, or NO_CHANGE.

   Module name

   Allows you to assign a name to the generated block memory configuration. This will help to distinguish multiple configurations in the XPE sheets.

3. When you have filled out the values for this block memory, click Create.

   A row in the Block Ram sheet and a row in the Logic sheet will be filled in with the information you entered in the dialog box.

4. For each block memory type in your design, fill out the dialog box and click Create.

   Each time you click Create a row is added to the Block RAM sheet and the Logic sheet.

5. When you have configured all of the block memory in your design, click Close to close the XPE Memory Generator dialog box.
