Hello Daixiwen,

Thank you for the reply. And I think I have seen that checksum hardware accelerator example in the SOPC user manual.

The issue with that is, that is too much a high level for a beginner to start with.

It does not explain how to create a sw.tcl file and the *.c and *.h driver files (I think all those files are to be hand-coded).

Also the build process explains a NIOS II SBT build, and which is specific for a Cyclone IV device.

I use the DE1 board here, which has the Cyclone II device in it.

So is there any simple example for the SOPC builder component which I can refer to? That would be a huge help.

Thank You,

Akhil
