How to implement DP RAM written in RTL using M20K?

[AGaru1]

Hi all,

can you please help me to synthetize a ram module written in vhdl as M20K? Unfortunately Quartus is synthetizing it using flipflops so it ends up in a big waste of them. Is there any particular attribute to write on the rtl or any constraints to specify on the qsf file? Or also any particular coding style for the rtl in order to make it possible? I want to avoid using the Intel DP RAM from the Altera library because the timings are different and a great modification of the design would be required.

Thank you so much.

Yes, what you can do is right click on the vhdl/verilog files, insert template.

From there, you can find the method to rewrite the code for your ram and there is also attribute that you can use to infer M20k

Thank you so much, i didn't know that.
