Quickstart Guide

Demo Setup and Instructions

Programming the FPGA

1. Invoke the Hello_FPGA_GUI. Select the appropriate COM port from the drop down list and click

Connect . The GUI displays COM Connected on successful connection.

2. In the FPGA Programmer tab, click browse and select one of the FPGA Programming ﬁles

(.dat).

3. Select PROGRAM under Action from the drop-down list and click Run.

4. Upon successful completion of FPGA programming, user LEDs 2 and 3 starts blinking on the

Hello FPGA board.

5. Unplug the USB cable from the hardware and follow the preceding instructions to reconnect the

cable.

6. Click Power Graph tab to see the FPGA Core Power information.

7. Click FPGA Demo tab to run the demo for the programmed ﬁle (.dat).

Connect the USB cable from the host PC to USB 2.0 port of the Hello FPGA board.

See Microchip Logo on the display followed by the Hello FPGA board image.

Running a Digital Signal Processing Application

Hello FPGA Kit

Quickstart Guide

After programming with

Demo1_FIR_FILTER_Vx.x.dat ﬁle,

follow these steps:

1. Go to the FPGA Demo tab

> Input Parameters tab.

2. In the Filter Generation

pane, select Filter Type,

Filter Window, enter

Cut-off Frequency (MHz)

and click Generate Filter

to generate the ﬁlter

coefﬁcients.

3. In the Input Signal

Generation pane, enter the

Input frequencies. Click

Generate Signal and observe

the Filter Input.

4. Click Start to send the

generated input signal, ﬁlter

coefﬁcients to SmartFusion2

FPGA and observe the

ﬁltered output.

Quickstart Guide

5. The ﬁltered output from

SmartFusion2 FPGA as

per the ﬁlter conﬁguration

can be observed on the

Filter Output tab.

6. In the Text Viewer tab, you

can see the numerical values

of the graphs plotted in the

Filter Input and Filter Output

tabs.

Quickstart Guide

7. Click Autosweep, the GUI

automatically sweeps

one of the input signal

frequencies (Sweep)

through a range of values

and sends to the FPGA to

perform ﬁlter operation .

Filtered output from FPGA

is displayed on the right .

Running an Image Processing Application

After programming with

Demo2_HF10_CAM_LCD_FF_Vx.x.dat

ﬁle, follow these steps:

1. The video captured from

camera is displayed on

LCD with FPGA running

Image Signal processing.

If required, turn the lens to

adjust the focus.

2. Go to FPGA demo tab to

adjust contrast, brightness

and color balance through

sliders The Contrast,

Brightness, and Color

Balance can be adjusted

through the sliders.

3. Click Reset to set the

default values.

Running an AI Digit Recognition Application

Hello FPGA Kit

Quickstart Guide

After programming with Demo3_

HF10_DIGIT_CNN_FF_Vxx.dat ﬁle,

follow these steps:

1. Go to the FPGA Demo tab.

The FPGA captures the

video from camera and runs

Convolution Neural Network

(CNN) to recognize the digit

in the video stream.

2. Point the camera to align

green box around a digit

with the green box on the

LCD. The recognized digit is

displayed on the LCD and

on the left side of the GUI

window.

3. Use Digit Set 1, Digit Set 2

or Digit Set 3 to test with

different fonts.

Measuring Power in Active and Low Power Mode

The Power Graph Tab can be used

to observe the FPGA Core Power (W)

and initiate Flash Freeze.

1. In the Flash Freeze pane,

click Flash Freeze Entry

to switch the FPGA from

functional mode to low

power mode and observe

the power drop in the GUI.

2. Click Flash Freeze Exit to

switch the FPGA back to

functional mode. The time

to exit Flash Freeze mode

can be observed in the

Flash Freeze pane.

Licensing

To create custom applications for the Hello FPGA kit, a free Libero SoC Design Suite silver license

is required. For more information, see https://www.microsemi.com/product-directory/design-

resources/1711-licensing#overview

Documentation Resources

For more information about the Hello FPGA Kit, including schematics and demo guide, see the

documentation at the resources section of the Hello FPGA web page.

Support

Technical support is available Online at https://www.microsemi.com/product-directory/product-

Serial Terminal

Each demo that comes with the GUI

is identiﬁed by the design version set

in the dat ﬁle. Version numbers 4,6,

and 7 are reserved. User should not

use these design version numbers

during dat ﬁle generation of their

custom designs. GUI reads the

current design version on the Kit and

loads the appropriate FPGA Demo on

a successful connection. For custom

designs, a generic ‘Serial Terminal’ is

loaded instead of FPGA Demo. This

tab enables the user to communicate

to the FPGA over Serial protocol.
