Overview
The Digilent Cmod S6 is a small, 48-pin DIP form factor board built around a Xilinx Spartan 6 LX4 FPGA. The board
also includes a programming ROM, clock source, USB programming and data transfer circuit, power supplies, and
basic I/O devices. There are 46 FPGA I/O signals that are routed to 100-mil-spaced through-hole pins, making the
Cmod S6 well suited for use with solderless breadboards. At just .7” by 2.6” inches, it can also be loaded in a
standard socket and used in embedded systems.
1 Configuration
The FPGA on the Cmod S6 can be configured using the on-board Adept USB interface or from the on-board Quad-
SPI Flash memory. Configuration files can be programmed using Xilinx’s ISE 14.2 (or higher) development tools,
using Digilent’s Adept system, or using older versions of the Xilinx tools if Adept is also installed. Xilinx’s ISE/Impact
programming tool and Digilent’s Adept tool will recognize the board and/or FPGA when the board is attached to a
PC using a Type-A to micro-B USB cable.
Xilinx’s iMPACT tool and Digilent’s Adept can both be used to program the FPGA, and iMPACT can also be used to
program the on-board QSPI Flash. Please refer to the ISE and/or Adept documentation for more information on
using the configuration software.
When using Digilent’s Adept software for programming, a dialog box available from the Config tab can be used to
select a configuraiton file. Pressing the Program button will program the FPGA with the selected file. This may
result in a warning that the configuration file was built for an unknown device; however, this warning can be
ignored.
When using Xilinx’s iMPACT 14.2 (or higher) software for programming, a .bit file can be associated with the FPGA
by right-clicking on the FPGA icon, selecting the desired .bit file, and clicking Program.
