In the Quartus® II software release version 14.0 update 2, there is a Qsys bug in the internal oscillator IP component (ip/altera_int_osc/altera_int_osc_hw.tcl) for the MAX® 10 device. When compiling your design, you might generate an error such as "<signal name> has unknown type clkout," and the altera_int_osc_hw.tcl might declare invalid parameters.
You must use the
clkout pin as the conduit interface
in Qsys. This issue will be fixed in a future release of the Quartus
