[Altera_Forum]

Hi,  

I should use off chip sdram on my de2 altera project. Does someone know if is possible to implement the sdram without sopc builder?  When i use sopc builder i have some problems with license and open core plus megafunction... i have quartus web edition .  Thank you.  P.s. I would to implement sdram fsm controller. Is this the right way?

As posted before ... 

 There is an OpenCores project that is called "Zet PC platform" that runs Windows 3.0 Opencores has a link to this web page...  http://zet.aluzina.org/index.php/pictures (http://zet.aluzina.org/index.php/pictures)  This project has a SDRam IP you could try. you need to download the sources and look for "yadmc" that is the sdram controller ip. this project shows how to use this ip and parametrize it for your own sdram devices without sopc

sorry but i see only pitcures... 

can you post the link of the project?

[Altera_Forum]

i've found it. 

Thank you so much. It is in verilog language. My project is in vhdl language. Can i mix vhdl and verilog files in my project?

[Altera_Forum]

yes you can :) 

 Quartus is able to compile a mix of VHDL & verilog HDL as well as schematic entry and Altera HDL

But Modelsim will not be able to simulate a mixed VHDL/Verilog design if you don't pay an extra license, IIRC.

That is correct, but it has been discussed on nios forum (if i am right) wheter this is still true or not. i can't remember that somebody said it is still so as it was all those years VHDL or Verilog HDL with this license 

a couple of years ago you had to decide what kind of license (VHDL / verilog) you want for modelsim each time you ask altera for an updated license.
