7 Installing the TAP CONNECT JTAG Cable Windows 7 and Windows 8.x Installation The TAP CONNECT JTAG Cable attaches to a PC with a USB A-to-mini cable; connect the cable to the PC. If the OS is Windows 7 or 8.x, the drivers will automatically install. The cable includes two USB Ports: FT2232H Channel A and FT2232H Channel B. Drivers for both channels have to be installed, as the screens will indicate. Note: USB 2.0 only with Windows 7 USB 2.0, USB 3.0 with Windows 8 Troubleshooting the Cable Driver Installation The New Cable does not enumerate: Windows 7 and Windows 8.x automatically installs the drivers. However, should the TAP CONNECT JTAG Cable not enumerate, open the Device Manager by going to: Control Panel>Hardware and Sound> Devices and Printers>Device Manager In the Device Manager your drivers should be found under Universal Serial Bus controllers. Should you not see the drivers located here, look to see if the Device Manager has the cable listed under Other Devices. Select one of the two channels, right click, select Update Driver Software. If necessary, repeat for the other channel. ontap does not recognize my cable: Please follow the steps outlined above. Odds are your cable is not being detected because the driver for the older ontap USB Cable may be interfering with the new device. 7

8 Installing the TAP CONNECT JTAG Cable (cont d) When the TAP CONNECT Cable drivers are properly installed, they will appear as shown below in the Device Manager>Universal Serial Bus controllers list. The new drivers are called USB Serial Converter A & B Figure 4: The new TAP CONNECT JTAG Cable drivers are installed. 8

9 Setting up the TAP CONNECT JTAG Cable Selecting the Cable Open ontap and from the menu bar, select Test and Programming Cable, as seen in Figure 5. This will open the Select a test/programming cable adapter screen (Figure 6), where the cable type will be declared. Figure 5: Select Test and Programming Cables from the menu ontap s home page to begin the setup process. 9

10 Setting up the TAP CONNECT JTAG Cable Selecting the cable (cont d) With the Select a test/programming cable adapter screen open, click on the Selection tab. Now, select the ontap USB Cable radio button. Next select the ontap USB Cable tab. Figure 6: Make the cable selection from this screen, then proceed to the ontap USB Cable tab. 10

11 Setting up the TAP CONNECT JTAG Cable Selecting the cable (cont d) The TAP CONNECT JTAG Cable screen should display the cable s name, as shown below in Figure 7. At this point, the USB cable is enabled and ontap can run existing SVF files from any of the Test screens and from ProScan. If you have installed an older ontap USB cable and your computer did not automatically recognize and update your new TAP CONNECT JTAG Cable, you may have to manually update the drivers. This can be accomplished by opening the device manager and searching through the USB Devices list for the FT2232C Channel A and Channel B, which is the older ontap device. Once you locate these devices, right click on them and select the option to automatically search for and install new drivers. Figure 7: When the TAP CONNECT JTAG Cable names are displayed, the cable is enabled. 11

12 Setting TCK Rate and Internal Vref Setting the TCK Rate To change the TCK rate, move the slider in the ontap USB Cables tab. The selected rate appears in the edit box to the left (Figure 11, p. 15). Note: some applications may run only at slower settings. The TCK rate for this cable is linearly adjustable from 285KHz to 15MHz, then it jumps to a maximum speed of 28.8MHz. Because each channel is independent, both channels will and can run at speeds up to 28.8MHz. Cable Power and Internal Vref The cable is self-powered at 3.3V. However, if you are working with an application that does not have its own voltage reference brought out to the JTAG connector, you can connect the Vref pin to the cable s adjustable internal voltage source (Figure 8). This can be done on each of the channels. By placing a shunt or jumper across the two voltage adjustment pins, the Internal Vref is activated. Attach an oscilloscope or voltmeter across the JTAG Vref and GND pins and adjust the voltage with a flat -head screwdriver to the desired voltage. (Refer to cable pin-outs diagram, pp 4, 5). Voltage Adjust Screw (For use when not connected to a UUT s Vref) +1.8V +5.5V Standard +0.92V +3.6V low Voltage Use a small flat-head screw driver to adjust. Scope measurement here. Figure 8: Adjusting the voltage on the TAP CONNECT JTAG Cable. Internal Voltage Adjust Jumper Place a shunt on these two pins and a scope on the pin marked with the yellow arrow. 12

13 Creating Adaptor Files Adaptor Files Procedure to Associate SVF Files to the TAP CONNECT JTAG Cable Ports An adaptor file is created to match specific USB cables to specific JTAG chains in test files. The output from the ontap test development screen is an SVF file. An SVF test can include one or more JTAG chains. Each of those JTAG chains must be associated with a channel port on the TAP CONNECT JTAG cable. Adaptor files are used to accomplish this. The adaptor files are created using the following procedure: 1. Open the Test screen; from the Test screen, click on the Tap Connect button (Figure 9). 2. In the Test and Programming Cable screen, click on the project folder icon for the drop-down menu which allows you to browse to your project folder. Select your project and click OK (Figure 10). 3. With project folder loaded, first set the TCK rate using the slide control. The selected rate appears in the edit box to the left (Figure 11). Next, note that all SVF test files appear in the upper left pane of the test/programming and adaptor screen (Figure 11). Any connected TAP CONNECT JTAG Cables appear in the lower left pane of the test/programming and adaptor screen (Figure 11). 4. To link an SVF file to a cable port, click on the SVF file name in the upper left pane (Figure 12), then click on the appropriate cable and port in the lower pane (Figure 12). Once you have made the svf and cable port selection(s), note that your selection of cable number and port will appear in the upper left pane (Figure 12). Click on Write Adaptors. Repeat this process for the second cable port, if using. 5. Once the tests and cable ports are properly linked and the adaptor files have been written, you will see a green check next to the SVF file in the upper left pane (Figure 13).Click OK to accept (Figure 13). Note: An adaptor file is always required. If you only use Chain A or B you do not need to change the adaptor file if you swap cables. However, when using applications requiring more than one TAP CONNECT JTAG Cable or if use other than chains A or B, an adaptor file must be created if you swap out the cable. 13

14 Creating Adaptor Files Step 1 Open the Test screen, then click on Tap Connect to access the cable selection screen. Select Tap Connect Figure 9: Access the Tap Connect menu from ontap s Test screen. 14

17 Creating Adaptor Files Step 4 To link an SVF file to a cable port, click on the SVF file name in the upper left pane (Figure 12), then click on the appropriate cable and port in the lower pane (Figure 12). Once you have made the SVF and cable port selection(s), note that your selection of cable number and port will appear in the upper left pane (Figure 12). Repeat this process for the second cable port, if using. 3. Click Write Adaptors. Repeat for Channel B. 1. Click SVF file here. 2. Match here. Figure 12: Link the SVF file to a cable port by clicking on the SVF file name in the upper left pane, then click the appropriate cable port in the lower left pane. Click Write Adaptors. Repeat for the next chain. 17

18 Creating Adaptor Files Step 5 Once the tests and cable ports are properly linked and the adaptor files have been written, you will see a green check next to the SVF file in the upper left pane (Figure 13). Click OK to accept. The green check indicates the adaptor file has been written. Now click OK. Figure 13: A green check next to the file name (upper left pane) lets you know your adaptor files(s) has been properly written. 18

19 Self-Test the TAP CONNECT JTAG Cable Procedure to Self-Test Included in your ontap TAP CONNECT JTAG Cable kit, you will find: ( 1 ) TAP CONNECT JTAG Cable pod ( 1 ) A to Mini Cable ( 2 ) Two-pin Shunts ( 2 ) Xilinx Fly Leads or Ribbon Cable To complete the test you will need a pin to connect TDO to TMS, TCK, TDI and INIT. Executing the test with the Xilinx Fly leads is the easiest method of self-test. However, if using a ribbon cable, a single wire jumper can be used. The standard TAP CONNECT JTAG Cable has been factory set at 3.3V. However, should the test not perform, please check the internal voltage source. To do this, set the internal voltage source to 3.3V by adjusting the potentiometer and measuring the voltage between the internal voltage source pin (next to the connector) and the GND pin (ref. Figure 8, p. 11). Note: For the purpose of performing the Self-Test, the internal voltage source for the TAP CONNECT LOW-VOLTAGE Cable should be set at 3.3V. Self-Test Method 1. Power the TAP CONNECT JTAG Cable with the A to mini USB cable. 2. Place the shunt on the two pins that connect the Internal Voltage Source to the Channel A Vref pin (Figure 14). 3. Connect the fly leads to Channel A on the board. 4. Select the TDO lead and place the pin into it. 5. Launch ontap; select the Test page. 6. Once in the Test environment, on the bottom right side of the Test page, you will see: Test Your Cable (Figure 15). 7. Insert A in the TAP edit box (Figure 16). 19

20 Self-Test the TAP CONNECT JTAG Cable (cont d) 8. When the TDO lead with the pin is connected to TMS, select the TMS box in the Test Your Cable section (Figure 16). 9. When the correct connector has been selected, the test will run automatically. If the loopback is connected, then the TAP pin is working properly (Figure 16). 10. De-selecting the box will stop the test. 11. Perform this test on each of the leads (TMS, TCK, TDI, and INIT). 12. When Channel A has been tested, repeat these steps for Channel B. Place shunt on these two pins. Figure 14: TAP CONNECT JTAG Cable Pod and pins that connect Voltage Source to the Channel A Vref. 20
