I have selected Atlys Spartan 6 development board. In Set target interface, when i am specifying interface as "Specify FPGA Pin{'LSB,..'MSB} as pin numbers [1:32] for sfix32_EN22 port type, its showing failed FPGA Pin input: FPGA Pin input should be cell array with format {'LSB',..,'MSB'}. What exactly pin numbers should be specified in FPGA pin?

Hi Tim,
Thanks for your response. I tried specifying pin numbers as {'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32'}
But its showing the same error.
Invalid FPGA Pin input should be a cell array with format {'LSB',..,'MSB'}

Hi Pooja, The "FPGA pin" box is used to specify FPGA pin location names, so HDL Coder can connect these FPGA pins to the port you specified. You have to find out the correct FPGA pin names by reading the Atlys board manual. For example, if you want to connect to LEDs, the pin names are {'U18', 'M14', 'N14', 'L14', 'M13', 'D4', 'P16', 'N12'}. The cell array format in your last post should be correct. You can try to specify the pin names on a port with less bitwidth to get started.

Hi Wang,
Thanks for response.
If i have output of 16 bits, can I directly use VHDC connector pins to assign output, the VHDC pins as given in manual IO1-P TO IO20-P with pin numbers.

You cannot use MATLAB numeric array syntax here; as the error message states, you have to specify each pin number as a string, combined together in a cell array:
{'1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32'}
