Honored Contributor --- Quote Start --- I have even tried using the OpenCores I2C wrapper found at alterawiki.com/wiki/OpenCores_I2c.

You need to change some lines of _hw.tcl file according to Qsys required syntax. I suggest you take a *_hw.tcl file from another Qsys built-in component and use it as a template for your i2c custom component.
