sdo_from the_epcs_controller Assignment

I am currently trying to upgrade a design (well more redo) from Quartus 13 to 16.

I doing so i have tried using the altera_epcq_controller in place of the Legacy Flash controller in order to access the EPC16 in order to get the code for the NIOS cpu.

Unlike the old core the 4 pins required tin interface are not exported to the top level as per the Documentation.

When i add the 4 assignment as per docs

• data0_to_the_epcs_controller = DATA0

• sdo_from the_epcs_controller = DATA1,ASDO

• dclk_from_epcs_controller = DCLK

• sce_from_the_epcs_controller = FLASH_nCE

when compiling the project i get the following error

Critical Warning (136021): Ignored assignment LOCATION which contains an invalid node name "sdo_from the_epcs_controller"

The other 3 Nodes are found and map to the correct pins.

Any one know what the name of the node is or if it even required i have to assume this is the same as the node epcs_flash_controller_0_external_sdo in the legacy core.

Any help would be great

Cheers
