Error (11176): Alt_sld_fab.alt_sld_fab.stfabric.demux: "Number of Output Ports" (numOutputInterfaces) <Number of Channels> is out of range: 1-16

Description

You may see the above error in Intel® Quartus® Prime Software version 15.0 when implementing a transceiver design that contains greater than 16 channels and has a separate ADME (Altera Debug Master Endpoint) interface per channel in Arria® 10 and Cyclone® 10 devices.

Resolution

To work around this problem, you can change the constant in the following file:

*quartus/libraries/megafunctions/altera_debug_master_endpoint.vhd

–from: constant NUM_CLOCKS  : natural := 0;

–to: constant NUM_CLOCKS   : natural := 1;

This problem will be fixed in the future version of the Intel® Quartus® Prime Software.
