We have DXP with all of the options except IP processors, including fpga support, but no Nanoboard. My need is to build simple logic block replacement fpgas, and insert them into pcb designs. The current fpga is an Altera EPM3128A.

Made it through the schematic and pcb phases, including a schematic of the fpga functions.

I was under the impression that at this point DXP would use the fpga schematic to generate a VHDL file that I could compile with the appropriate Altera software. When I go to Tools>Convert>Generate VHDL From Part, andclick on thefpga symbol in the schematic, it generates a VHDL file with only entries for the control signal pins.

My call to phone support ended with the explanation that the user is supposed to fill in the details of the logic in this VHDL file and compile it manually.

The examples in the manual (using the Nanoboard) certainly indicate that there is some sort of automatic file and compilation going on. Am I missing more than just the physical Nanoboard, like additional software?

If DXP won't generate the VHDL file from the fpga schematic, what is the point of generating it in the first place? It seems that I could just start with the Altera software.

Any help would be seriously appreciated.

I can't help with DXP specific info, but I have done this with P99SE. You ouput a netlist from the schematic, and select VHDL as the net list format. (I had to massage the netlist a little bit to make it compatible with Xilinx's VHDL compiler, but I did get it to work.
