UltraRAM - implementation via Block design (1MB)

Jump to solution

Hi All,

 

It's my first time here so please be gentle :)

 

I am trying to implement a 1MB ultraram in my design.

In order to do so I have used an AXI Interconnect, AXI BRAM controller and Block Memory Generator.

 

The Block Memory Generator was set to the followings:

1. mode - BRAM Controller

2. Memory Type - True Dual Port RAM

3. Primitive type - URAM

 

Since the URAMs are 72bit wide and 4K deep I have set the AXI BRAM Controller to 64bit wide, and at the Address Editor i have changed the memory range to 1M (we are aiming for 1MB memory size).

 

unfortunately I keep getting a critical massage stating the following: 

"[BD 41-1266] </axi_bram_ctrl_1/S_AXI/Mem0> at <0xC2000000 [ 8K ]> and </axi_bram_ctrl_1/S_AXI/Mem0> at <0xC2000000 [ 1M ]> are mapped into related masters </axi_ethernet_0_dma/Data_MM2S> and </microblaze_0/Data> at different ranges"

 

So my questions are:

1. How can I solve the critical issue?

2. Is it the right way to implement 1MB ultraram using the block design diagram.

 

Thanks in advance,

Refael Torika

The resolution is 

In the address editor @torikar missed one section on changing it 1M instead of 8K.
