I could not find the FPGA pin locations of the 64Mbit SDRAM. The ucf file (https://github.com/matrix-io/matrix-voice-fpga/blob/master/voice_core/voice.ucf) does not include them. Would it be possible to update the ucf file, or point me to the location, where I can find the pin locations? I would like to include the SDRAM in an FPGA design.
