The _sw.tcl belongs in the same search path as the _hw.tcl you used to create your Qsys system. So if you just unzip the .zip and have added the I2C to your Qsys, then the _sw.tcl is probably in the right place.

It looks like the problem is that for whatever reason, in the files in the .zip, the _hw.tcl and _sw.tcl don't agree on the name of the hardware block.

In the _hw.tcl, the name is "i2c_opencores" [like it says on the wiki page].

In the _sw.tcl, the expected name is "opencores_i2c".

Try changing the _sw.tcl so that: 


set_sw_property hw_class_name i2c_opencores

And then restart the bsp-editor
