Hi,

I can't succesfully implement I2C opencore by Component Editor.

First, for the Verilog version, when I added i2c_master_top.v, the Errors Analyzing found wrote: can't open Verilog Design File "i2c_master_defines.v", but this file is near i2c_master_top.v Why?

Second, for the VHDL version is no errors, but I can't find "always0" in "Signal Type" column (in Interface to User Logic it was), but I can resolve this problem by type "external" and out of SOPC component tie to ground (it is good idea or not?).

But what about two chipselects? In Interface To User Logic I can set two chipselects signal but in Component Editor I can't? What I have to do?

Thank you for your advise
