2FPGA Offline Programmer Instructions
2.1 Overview
Offline programmer is a device that offline programs GW1N(R) chips.
It has the features of data confidentiality, portability, multi-path
programming, etc. It is suitable for rapidly large-volume production at the
factory and is convenient for maintenance personnel to carry out. The
offline programmer can simultaneously program four FPGA devices, and
automatically detect device access and program in a single interface,
which greatly increases the mass production rate.
The offline programmer encrypts and saves the data using an
AES-128 advanced encryption algorithm, and the key is saved after
several times of encrypting. AES is a set of internationally recognized,
commonly used and secure encryption standards that ensure securely
delivering data.
2.2 Offline Programmer Instructions
The offline programmer can be configured and managed using the
offline programmer software, such as data stream file management, upper
burner count management, and writer firmware upgrade. The software
supports Windows 7 and above operating systems. After configuration, the
offline programmer can be connected to the FPGA to program.
2.2.1 Software Download and Driver Installation
The relevant software and driver package can be downloaded at
Gowin website or contact the sales for help. Install the driver and the path
is https://www.gowinsemi.com/en/support/devkits_detail/7/. After
installation, use USB cable to connect the programmer and computer, and
USB Serial Port(COMxx) appears on the port, that is, the driver is installed
successfully, as shown in Figure 2-1.

2.2.2 Configuration Interface
OPmanager.exe is the associated software in the "bin" directory. Open
OPmanager.exe, and the configuration options are shown in Figure 2-2.
Figure 2-2 Software Configuration Interface
1. Programming File: The selected one is GW1N1.fs. Open the
management tool and generate the key randomly, encrypt the data
stream files and store them in the programmer.
2. Vcc1 voltage is set as1.2v, Vcc2 is set as 3.3v. The supported voltages
are: 1.0v, 1.2v, 1.5v, 1.8v, 2.0v, 2.5v, 3.3v.
3. Verification: Options are the status code, read-back, or no verification.

Note!
Status code: Determine whether the programming is successful or not according
to the status code read from the FPGA after finishing programming data stream
files.
Read-back: Determine whether the programming is successful or not according
to the consistency of writing and reading after finishing programming data
stream files.
No verification, that is, only prompts the completion of programming.
4. The max. programming times: If it sets 100, “programming times : Error”
will pop up on the LCD of the offline programmer if the programming
times are greater than 100.
5. Clear programming times: Check to clear programming times.
6. Retry times if failed: Retry x times automatically if failed, and error will
be reported if x times failed.
Note!
1.5 version does not support the setting for the time being.
7. Delay after programmed: Delay x seconds after programmed,
indicating the result of programming.
8. Configure to programmer: Configure the checked information items to
programmer.
9. You can clear the configured data stream file, secret key, programming
times, and the upper limit value of programming times via resetting
factory data.
2.2.3 Configure to Programmer
The associated software is required to configure the programmer.
Open the OPManaer.exe software to configure it, as shown in Figure 2-3.
The configuration steps are as follows:
1. Select the data stream file (.FS).
2. Select 1.2v as Vcc1.
3. Verification selection: No verification.
4. Set the max. programming times or leave it blank.
5. Click the "Configure to Programmer" button.
6. Restart the programmer after configuration.

Figure 2-5 Connecting Programmer to SocketBoard
The quad JTAG programming interfaces share the TCK, TDI, and TMS
signal lines. After the programmer sends commands, the four FPGA
respond and can be programmed simultaneously. Operation steps of
programing four FPGA devices simultaneously are as follows:
1. Programmer is powered on and start;
Note!
Support USB power supply or 5V power supply.
2. Connect four FPGAs to the programmer;
3. Press the green Program key, the screen displays detecting the device
and the corresponding ID CODE is displayed after the device is
detected. The corresponding indicator turns green after the
programming is done successful.
Note!
In this mode, n (<=4) FPGAs can be programmed if they are connected. The programming
interfaces of 1.2.3.4 can be selected optionally.
2.2.5 Program One FPGA Automatically
In the automatic programming mode, the programmer can
automatically detect the new FPGA. It will program automatically if a new
FPAG is connected. Currently, automatically programming only supports
one FPGA, and only interface 1 of the programmer supports detecting and
programming automatically. Operation steps of programing one FPGA
automatically are as follows:

1. Programmer is powered on and start; “AUTO-PRO-MODE” will be
displayed after pressing the program key for 5 seconds, and then the
programmer enters the auto programming mode;
Note!
Support USB power supply or 5V power supply.
2. Connect one FPGA to interface 1;
3. The screen displays detecting the device and the corresponding ID
CODE is displayed after the device is detected. The corresponding
indicator turns green after the programming is done successful.
4. Disconnect the FPGA from the interface1, and then connect it to the
interface 1 again. The programmer will automatically program the
stream file to the FPGAdevice, and you do not need to press the green
programming key.
Note!
The automatic detection is used to detect whether there is a device connecting the
programmer; if a device is connected, it will be programmed automatically. If not, the
programmer will continue detecting and waiting for the new device.

2.5 Notes
1. When multiple devices are programed simultaneously, only the same
series of devices are supported. For example, all the GW1N-1 devices
or all the GW1N-4 devices.
2. The data stream file is configured in the offline programmer. Select the
FPGA to be programmed according to the screen prompt: "currently
support: GW1N(R)-x", to avoid other damage to the FPGA.
3. When configuring the offline programmer or programing the update file,
you need to manually cancel it when the progress bar is stuck at a
certain progress, and then restart the programmer.
