The internal oscillator IP component does not work for MAX 10 devices

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    Critical Issue

    Description

    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.

    Resolution

    You must use the clkout pin as the conduit interface in Qsys. This issue will be fixed in a future release of the Quartus II software.
