Error (15629): Atom "address_pres_reg[0]~3" is dependent on unconnected input ports

Environment

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

    Due to a problem in the Quartus® II software versions 14.1 and 15.0, you may see this error when compiling a design that includes the ALTGX_RECONFIG IP and targets Arria® II GX,  Arria® II GZ, Cyclone® IV, or Stratix® IV devices.

    The error occurs when the number of channels controlled by the reconfiguration controller exceeds six for Arria® II GX and Arria® II GZ, four for Cyclone® IV GX, or six for Stratix® IV.

    Resolution

    To work around this problem, either compile your design using the Quartus® II software version 14.0 or ensure that you do not exceed the relevant number of channels controlled by your reconfiguration controller.

    This problem is resolved in 15.0.1
