Hello,
I am trying to incude a DDR3 UniPHY Controller megacore to my design, but I am experiencing several issues. I am working on a TR4 development kit (TERASIC) based on the STRATIX IV FPGA (EP4SGX530KH40C2).
Basically I have generated the Megacore by using the Megawizard plug-in manager, I have parametrized my DDR3 block and I have generated the entity for my design.
After this I have normally instantiated the DDR3_Controller by defining it as a component inside my VHDL code, and I have connected it to the right signals. In addition I have mapped them to the pins on my development board by using the pin planner.
I haven´t still developed a control logic to drive the controller but this shouldn´t be a problem.
When I try to compile my design, it already fails in the Analysis and Synthesis step, and I get the following errors:
What is the problem here? How can I fix this?
I am getting problems both by compiling the examples automatically generated by the Megacore, and the examples developed with my board are quite bugged and fully not working...
BR,
Giovanni.
