2. How to Use Mimas – Spartan 6 FPGA Development Board
2.1. Components/Tools Required
Along with the module, you may need the items in the list below for easy and fast installation.
1. USB A to Mini B cable.
2. DC Power supply (Optional).
2.2. Connection Diagram


This diagram should be used as a reference only. For detailed information, see Mimas schematics at the end of this documentation. Details of individual connecto
2.3. USB Interface
The on board full speed USB controller helps a PC/Linux/Mac computer to communicate with this module. Use a USB A to Mini B
PC. By default the module is powered from USB so make sure not to overcrowd unpowered USB hubs. (the picture on the left sh
2.4. DC Power Supply
This module uses +5V power supply to function properly. By default the board is congured to use +5V supply from USB. So an external +5V
power is not required unless USB port is unable to supply enough current. In most cases USB ports are capable of providing enough
current for the module. Current requirement for this board largely depends on your application. Please consult FPGA datasheet for
more details on power requirements. If for any reason, an external 5V power supply needs to be used for the module, the Power select
jumper should be congured properly before connecting the power supply. Please refer to the marking on the board for more details.

2.5. Power Select
The Solder jumper is used to congure the power source for the board. The Solder jumper in pin 1 and 2 is shorted to switch the power source to on board USB p
use the external DC power.
2.6. On-Board Peripherals
8 LEDs and four micro switches are provided on-board for user dened purposes. These peripherals are connected to FPGA IOs and can be controlled from user R
have pull-ups on board so make sure to enable week pull ups on corresponding IOs in your design.
2.7. JTAG Connector
JTAG connector provides access to FPGA’s JTAG pins. A XILINX platform cable tool can be used to for JTAG programming.
2.8. GPIOs

3. Driver Installation
3.1. Installing on Windows
This product requires a driver to be installed for proper functioning when used with Windows. The driver
package can be downloaded from the product page. To install the driver, unzip the contents of the downloaded
driver package to a folder. Attach USB cable to the PC and when asked by Windows device installation wizard,
point to the folder where driver les are present. When driver installation is complete, the module should appear
in Windows Device Manager as a serial port (see the picture on the right). Note down the name of the serial port
(COM1, COM2 etc..). This information is required while programming the module with conguration tool.
3.2. Installing on Linux


To use this product with Linux, USB CDC driver needs to be compiled in with the kernel. Fortunately, most Linux distributions (Ubuntu, Redhat, Debian etc..) h
installed. The chances of you requiring to rebuild the kernel to include the USB CDC driver is very slim. When connected to a Linux machine, this product should
the /dev directory. Usually the name of the device will be “ttyACMx” or similar. The name may be dierent depending on the Linux distribution you have.
3.3. Installing on Mac
Similar to Linux, Mac operating system comes with the required drivers pre-installed. When connected to a Mac computer, the device should appear as a serial po
4. Generating Bit Stream for Mimas
HDL design needs to be converted to bit stream before it can be programmed to FPGA. Mimas at this time accepts only binary (.bin) bit stream created by XILINX
(http://www.xilinx.com/tools/webpack.htm). Once the HDL is synthesized, it is easy to create a binary bit stream out of it. Please follow the Steps below to generat
your design using ISE Web Pack.
Step 1: Right click on the “Generate Programming File” option in “Processes” window.
Step 2: Select “Process Properties” from the pop up menu. In the dialog box, check “Create Binary Conguration File” Check box and click “Apply”.


Step 3: Click “OK” to close the dialog box. Right click on “Generate Programming File” option again and select “Run”. Now you will be able to nd a .bin le in the p
le can be used for Mimas conguration.
5. Powering Up Mimas
Mimas can be powered directly from USB port so make sure that you are using a USB port that can power the board properly. It is recommended to connect the b
instead using a hub. It is practically very dicult to estimate the power consumption of the board, as it depends heavily on your design and the clock used. XILINX
estimate the power consumption. In any case if power from USB is not enough for your application, an external supply can be applied to the board. Mimas requir
a 3.3V and a 1.2V supply. On-board regulators derive these voltages from the USB/Ext power supply.
6. Configuring Mimas
The Mimas Spartan6 module can be congured by two methods,
a) Using Mimas conguration tool through USB.
b) Using the Xilinx programming cable..


6.1. Configuring Mimas Using Configuration Tool
Mimas has an on-board micro-controller which facilitates easy reprogramming of on-board SPI ash through USB interface. The micro-controller receives bit strea
application and program it in to the SPI Flash and lets the FPGA boot from the ash. The Mimas conguration application can be downloaded from www.numato.
Mimas is connected to PC, it shows up as a COM port in Device Manager. Run conguration application, select proper COM Port before downloading bit stream. C
select the bit stream le (.bin) and press “Program” button to download the bit stream. Wait till the download process is nished. Once the download process is o
controller will try to boot the FPGA from the SPI Flash automatically. Follow the below steps.
Step 1: Open Mimas Conguration Tool. Select the port no.(Refer “Driver installation” for more information on nding port no.) Click Open le and select the .bin
Step 2: Click on “Program” button. Wait till “Done” appears on the screen.
