Associate an individual mif file to each RAM memory instantiated by a "generate"

Hello,

I instantiate RAM memories with the following VHDL code :

 gen_inst_ram_0to7 : 
for i in 0 to 7 generate
inst_ram : ram
port map(
address_a => w_address_a(i),
address_b => w_address_b(i),
clock => clk,
data_a => w_data_a(i),
data_b => w_data_b(i),
wren_a => w_wren_a(i),
wren_b => w_wren_b,
q_a => w_data_out_a(i),
q_b => w_data_out_b(i)
);
end generate gen_inst_ram_0to7;

I would like to use memory initialization files (*.mif) but don't know how to link the 8 files to the 8 instanciations.

Could you give me a hint to do such thing ?

Thank you.

You can try to study the RAM VHDL design code in Quartus. In the new VHDL file, right-click and "insert template". Find VHDL > Full Designs > RAMs and ROMs > Single-Port RAM with Initial Contents. 

There is a part of the design code on how to use .mif file. Or you can instantiate it using the Quartus IP Catalog. Hope it helps.

Thank you for your answer but this template covers the case of using a *.mif file to set the initial state of an explicitly instantiated RAM block. My issue is about doing so when the RAM blocks have been instantiated using a "generate" statement.

Thank you  for your support.

Hello,

As requested, I replied to your answer, stating that it what well suited for my case but you didn't pursue. I was less available those last 16 month but we can now resume support.

My issue is about using *.mif files when the RAM blocks have been instantiated using a "generate" statement.

Thank you  for your support.
