ATF15xx CPLD ISP Software [ATMISP] –Quick Start Tutorial P. 1
ATF15xx CPLD ISP Software - ATMISP
Quick Start Tutorial
This tutorial introduces the features and usage of the ATF15xx CPLD In-System
Programming (ISP) Software [ATMISP] v7.x for the ATF15xx family of JTAG ISP
supported Complex Programmable Logic Devices (CPLDs). It describes the entire ISP
process from setting up the JTAG device chain file (.CHN) using ATMISP to executing the
JTAG ISP instructions onto the JTAG device on the target JTAG ISP hardware system. For
this tutorial, the ATF15xx-DK3 CPLD Development/Programmer board will be used along
with the ATDH1150USB USB based ATF15xx JTAG ISP cable. Please refer to the Getting
Started section of the ATMISP Help File for information on how to setup other ISP hardware
platforms.
Step I : Setup ISP Hardware
For this section of the tutorial, the ATF15xx-DK3CPLD Development/Programmer board is
used as the target ISP hardware along with the ATDH1150USB cable. To setup the
ATF15xx-DK3 and ATDH1150USB for programming, follow the steps below.
1. Connect the USB cable contained in the ATDH1150USB kit to the USB port of the
computer and the USB connector of the ATDH1150USB ISP cable.
2. Connect the 10-wire ribbon cable contained in the kit to the JTAG-A port of the
ATDH1150USB and to the JTAG header (JTAG-IN) of the ATF15xx
Development/Programmer board.
NOTE: The selection jumper at JP-TDO on the ATF15xx-DK3 board should be plugged into
the “TO ISP CABLE” side.

3. Insert the 44-TQFP socket adapter board (ATF15xx-DK3-SAA44) onto main ATF15xx-
DK3 board if it is not already inserted.
4. Set both the VccIO and VccINT selection jumpers on the ATF15xx-DK3 board to 3.3V.
NOTE: The Power Switch for the ATF15xx-DK3 must be turned OFF before changing the
positions of the VccIO and VccINT Selection jumpers.
5. Connect the 9V DC power source to the power connector at JPower of the ATF15xx-DK3
board.
6. Insert a blank ATF1504ASV 44-pin TQFP device into the 44-pin TQFP socket. Please
note that pin 1 of the device should be at the upper left hand corner of the socket facing
the U1 label.
7. Turn the power on by bringing the Power Switch of the ATF15xx-DK3 board to the ON
position.
For the older ATF15xx CPLD ISP kits, please refer to the corresponding User Guide for
information on how to setup the hardware to perform JTAG ISP operations. For custom
JTAG ISP target hardware systems, please connect the JTAG ISP download cable into the
appropriate connector and apply Vcc to the CPLD(s) and JTAG ISP download cable.
The ISP hardware setup process is now completed.
Step II : Setup ATMISP Software
The first step of an ISP flow is to create a new chain file in the ATMISP software. A chain
file (.CHN) contains the JTAG device chain information such as the device types, number of
devices in JTAG chain, JTAG operations, and the location of the associated JEDEC files that
are required to program a single or multiple-device JTAG chain in the target hardware
system.
1. To create a new chain file, the ATMISP software first needs to be launched either
through the desktop icon or the Start … Programs menu.
2. To create a new chain file, select the New command under the File menu or click on the
New shortcut button.
An existing chain file (with a .CHN extension) that was created by the ATMISP software
can be loaded into the software by using the Open command under the File menu or
the Open shortcut button.

3. The first piece of information that the software asks for when creating a new chain is the
number of devices in the JTAG hardware chain. Therefore, simply enter how many JTAG
devices are chained together in your target system. For this tutorial, enter 1and then
click OK since you will be programming a 1-device JTAG chain in Step III of this tutorial
using the ATF15xx CPLD Development/Programmer board.
4. Next you will need to specify the properties of each JTAG device in the Device Properties
window. First, you will need to select the target device type of the first device in the
JTAG chain. Clicking on the down arrow will open the list of all the supported device
types. For this tutorial, please select ATF1504ASV as the target device type.
In the JTAG Instruction field, you can specify which JTAG instruction to be executed on
this device in the chain. Please select Program/Verify to program and verify the
ATF1504ASV.
The next step is to specify the JEDEC file to be programmed into the target device in the
JEDEC File field. Click on the Browse button, change the directory to the
[..\JEDEC\ATF1504AS] sub-directory under the ATMISP installation directory and
then select atf1504.JED as the JEDEC file. Click OK to close the JTAG Device
Properties window when all properties are specified.
If there is more than one device in the JTAG chain, then the JTAG Device Properties
window will open again for the second device, third device, and so on until the JTAG
Device Properties window for the last device in the JTAG chain is closed.
A new chain is now created and it will be displayed in the Chain File Hierarchy window
of the ATMISP Software. You can easily add or delete devices by using the Add Device
or Delete Device command respectively. These two commands are available through
the Edit menu and the right-click drop down menu in the Chain File Hierarchy window.
To edit the device properties, you can use the Edit Device command in the Edit menu
or by double clicking any part of the chain in the Chain File Hierarchy window.

5. For ATMISP v7.x, the only cable type supported is the ATDH1150USB USB based
ATF15xx JTAG ISP cable and the only port type supported is USB (v1.1/2.0/3.0). If you
are using an LPT based JTAG ISP cable (i.e. ATDH1150VPC), please use ATMISP v6.x on
a Windows 2K or XP PC instead.
6. This chain file can now be saved by selecting the Save or Save As command in the File
menu or by clicking on the Save shortcut button. Saving the chain file is optional but
recommended.
This completes the ATMISP software setup process.
Step III : Execute ISP Instructions
Now that both the ISP software and hardware are properly setup, it is time to program the
JEDEC file [atf1504.JED] into the target CPLD [ATF1504ASV] on the target ISP board
[ATF15xx-DK3]. To start the ISP process, click on the Run button at the bottom of the
ATMISP window.
The programming process will now start and the progress bar will indicate the progress of
the programming cycle. Once the programming is completed, ATMISP will generate a
prompt indicating that the JTAG operation was completed successfully or not. The message
pane at the bottom will also show the information related to the programming process.
However, the atf1504.jed file was not created to show any meaningful display on the LEDs
of the ATF15xx-DK3.
