How can I use M9K RAM Memory in CycloneIII ??

--- Quote Start ---

Hello Everybody !..

I have seen in CIII datasheet that it has a different kind of RAM block called M9K, with higher frequency.

When I use "reg" is this a M9K??

I Use Verilog, How can i define and use this Memory Block?

A solution without using SOPC builder is preferred.

Thanks

Hi,

you can do that by using :

reg [0:7] my_ram[0:63] /* synthesis ramstyle = "M9K" */;

But why do you want to specify the RAM implementation ?

i have a solution of my project which has a lot of shift registers and i can have maximum 125 MHz in my algorithm.

I saw that M9K type ram block has a very high frequency and wondered if i can increase my frequency..

Hi,

do you have problems to achieve your required clock speed ? Are you shift registers as register implemented ?

Kind regards

Use the MegaWizard plug-in manager if you want to create a ram-based shift register. It's under the "Memory Compiler" section.

Yes, My registers are defined as you mentioned above, like this.

reg [0:7] my_ram[0:63]

I don't have a trouble of speed, my current solution works fine but it would be fine it it could work faster.
