How do I connect EPCS signals to device pins?

Altera_Forum · ‎09-21-2012

I'm building a Cyclone IV design using EPCS configuration. I have instantiated an EPCS serial flash controller in my Qsys design and exported the EPCS ports (dclk, sce, sdo, data0). These four ports are visible on the block boundary in the .bsf file.

How do I connect these ports to the dedicated programming pins on my package using the block editor? I tried connecting pin symbols (three output, one input) to the ports, then naming the pins to the default names and pin locations in the pin planner.

When I compile the design it fails with this error :

"Error (169135): Node name ~ALTERA_ASDO_DATA1~ causes a name conflict with a reserved programming pin name -- change the node name"

So it looks like Quartus doesn't like me using the default pin names.

What do I need to do to make sure the EPCS port on my Qsys block connects to the programming pins on the package?

Thanks,

Dig around in the device settings menu. There should be an option to bring those pins into your design safely. I just don't remember exactly where.
