SSRAM controller disappeared in Qsys 12.1

I used Quartus et Sopc builder 10.0 before, and I have a Sram controller in my Nios core.

It's in the category : Memories and Memory controllers --> SRAM --> Cypress CY7C1380C SSRAM.

But when I update my Quartus to 12.1, in the Qsys, the Sram controller disappeared ! There is no more sram controller in the ip list.

Even if I tried to open the old Sopc file with Qsys, it can't neither compile(generate) nor save into .Qsys if the old file contains a Sram controller.

Can any one help me with this? I really do appreciate.

PS: I have to use Qsys instead of SopC builder, it's a client requirement.

THX!!

    Hi,

    I'm at home now, so no access to the Qsys library but I'm sure that you could find the CY7C1380C in a generic controller of the library. You just have to add this controller in your Qsys system, double clik to customize it, and you will see options in a GUI right panel to select pre set parameters (CY7C, FLASH etc).

    If you don't find by your own, I'll post the right way tomorrow.

    pantxoa, Thx for your reply, i've found the CY7C1380C controller in the lib :

    altera\12.1\quartus\sopc_builder\model\lib\com.altera.sopcmodel.components.avalon.jar

    but I don't know how to add a component of format .jar ...

    Open your model in Qsys, in the Component library left panel, browse to Qsys Interconnect => Tri-State Components => Generic Tri-State Controller.

    Double clik to add it to your system.

    Then double clik to the component in your system, and you'll find a list of presets with the CY7C1380.
