Qsys new component - file path keeps changing

--- Quote Start ---

Hello,

i am working on my first Qsys project and it is running smooth with all built in components and one custom unit i connected in my .bdf file.

However, i was trying to a add the I2C unit from Altera wiki by the following steps:

1. New component (in Qsys)

2. add the top module to files (i2c_opencores.v)

3. Analyze file and connect all signal to the avalon counterpart and assign everything in interfaces and edit some names

4. no errors or warnings appear and i save

5. adding to system content is fine too

6. THEN: when i edit the file again or just generate and compile in quartus i get the errors

edit again error: Error: add_fileset_file: No such file .../VHDL/i2c_opencores/vhdl/i2c_opencores/i2c_opencores.v

the path is doubled??

same during compilation:

Error (12252): ...: add_fileset_file: No such file .../TDC_FPGA/VHDL/i2c_opencores/VHDL/i2c_opencores/i2c_opencores.v

no matter how often i specify the correct path it always returns to the wrong path!

Any ideas someone?

EDIT: i dont get this pathchange if i dont edit any names and leave everythin "as is".

EDIT2: however it also happens if i add multiple files!

When using I2C Opencores via QSYS and then compiling in Quartus II v.13.0 I get "Warning (12251): I2c_opencores_0: i2c_opencores is not in the library" which results in Errors.

In QSYS Generate went OK. What library is Quartus talking about?

Is it the same thing You were asking about? What is the way out?
