Hi,I am working with Cyclone III Development Kit, 3C120 FPGA device, Quartus 9, and I am trying to program a simple audio loopback project using TLV320AIC23 audio codec, which is placed on HSMC data conversion board. I used the HSMC reference manual pdf to find pin assignments to the audio codec through HSMC: AD_SDIO - AD3 AIC_BCLK - AA12 AIC_DOUT - AB4 AIC_LRCOUT - AA3 AIC_SPI_CS - AB11 AIC_XCLK - AA4 However, there are 3 pin assignments that I could not locate in assignment editor: AD_SCLK - AH1 AIC_DIN - W12 AIC_LRCIN - Y11 While trying to assign the pins to these locations, I got an error from Quartus: "can't recognize value PIN_<appropriate pin> as legal location". As I have checked in pin planner for this device (3C120F780C7), the W12 location seems to be stucked to VCC, Y11 stucked to GND and AH1 does not exist at all. Can somebody tell me the correct pin assignments that I should use to be able to work with the audio device? Thanks!
