HI we are using the SSRAM CY7C1470V33 in our design (instead of CY7C1380C which is part of the SOPC builder). How do we go about designing the system . Please help us regards, Bhandari

This component doesn't work with QSys. Apparently anything using an Avalon MM tri-state buffer needs an upgrade.

It ask you to perform the upgrade, which i do and it doesn't change anything.

QSys has a few extra features compared to SOPC. Check if the upgraded component defines all the required interfaces and if all ports are correctly connected.

Also check the base address: I can't remember right now if your SRAM component must be assigned to an absolute address or offset from TS bridge.

For more help you must specify what your problem exactly is: can't build Qsys? SRAM doesn't work at all? you can access SRAM, but you get data errors?
