The onTAP JTAG Controller
The onTAP JTAG Controller provides JTAG test and programming support for onTAP Boundary Scan Software. It offers higher speeds and simplified operation in both single and multiple-chain (multiple controllers) applications.
The Controller, either standard voltage, low voltage or low voltage-low impedance, may be used for the following applications:
- JTAG Test, including memory and cluster test
- Flash programming
- FPGA, CPLD and PROM configuration
- General purpose I/O
- The TAP CONNECT JTAG Controllers also provide the capability to run two chains at speeds up to 30MHz.
The onTAP JTAG Controller includes either two ribbon cable headers for direct connection to Xilinx-style headers or two flying lead connectors. Altera and other custom adaptors are available. The onTAP JTAG Controller attaches to a USB port on a PC with a Hi-Speed USB A-to-Mini cable.
The Cluster Test
Once an interconnect test has been developed, onTAP users frequently ask how to get started with cluster testing and flash programming. We have provided them with a way that is both efficient and flexible. Our cluster testing and flash programming models are reusable and may be adapted to other devices, as well as to application specific circumstances, such as demuxing a bus.
Memory and cluster testing is a powerful technique to check the connectivity between boundary scan pins and non-JTAG logic. Reusable test models for memory and other types of logic may be prepared in DTS, a high-level modeling language. DTS brings C-like flow control and expressions to the development of test models for non-JTAG devices.
Models may be prepared without regard to the details of boundary scan implementation, since onTAP’s Virtual Nails serializes a model’s test vectors into scans and automatically associates boundary scan pins, to act as driver/sensors, with non-JTAG device pins.
A simple example shows how DTS models can be used to set and test pin values on non-JTAG logic follows.
Sample DTS Model
The example below will write some data into memory addresses and call a clock. Data will then be read back from those addresses.
Mid-state shorts are bridging faults that result in a mid-state voltage level rather than a hard low or high level. In our experience at Flynn Systems when working with customers, we have found the condition occurs where short circuits exist as follows:
- between some boundary-scan pins on FPGA devices when only one boundary scan pin exists on a PCB net.
- across pins of resistor networks where the resistors lie between the shorts fault and scannable pins, and again where single boundary scan pins exist on the nets.
Mid-state shorts, like any bridging fault, can result in system level applications failures if not detected and cleared. The difficulty is that these shorts will not be detected by traditional boundary scan shorts detection algorithms that depend on sensing zero or one logic levels. The reason is that at the capture cell on single-pin nets, the capture value is equal to the value being actively driven from the same pin.
In the case of the resistor network, it is easy to see how the resistors can isolate the capture value from the value measured at the physical short. In the case of the FPGA pins the reasons are not quite so clear, but apparently sufficient impedance exists between the bidirectional cells and physical pins so that the input cell sees the value driven from the drive cell, not the value measured at the physical short.
Seen at P1 1110001111000011110000 // R1 isolates P1 from shorts value Z
Seen at P2 1110000000111111111000 // R2 isolates P2 from shorts value Z
Seen at Short 111000ZZZZZZZ1111Z000 // Z value results at opposing values
How Can MID-STATE Shorts be Detected?
As might be expected, MID-STATE shorts can be detected by a test pattern that uses tri-state, high impedance values, Z, in combination with zero and one values. One difficulty however, is that since Z is a passive condition and this approach is likely to result in unpredictable numbers of false failures. Another problem is that the number of potential test scans can be quite large.
onTAP addresses these difficulties in several ways. First, to achieve a manageable number of test patterns, standard Wagner test patterns, popular in boundary scan testing and known for their compactness and effectiveness, are employed. But instead of just using only 0-1 test patterns, 0-Z and 1-Z patterns are also used. This is effective and will detect the shorts, but will inevitably also produce false failures.
To deal with the false failures, onTAP actively interrogates all indicated net combinations at run time with a more exhaustive 0-1-Z pattern that eliminates false failures, but indicates any MID-STATE shorts conditions.
TestGen and AC Testing
AC Testing, also referred to as Dot 6 (from the IEEE Std. 1149.6) or AC EXTEST, provides a method to handle testing of the newer digital devices, such as the popular Broadcom communication devices. Incorporating the AC Testing into onTAP’s test tools expands users’ test capabilities, flexibility, and further enhances test fault coverage in a number of ways. Most apparent is the productivity gain achieved by testing to both IEEE 1149.1 and IEEE 1149.6 standards. The IEEE 1149.6 feature enables users to test AC Coupled circuits and differential pairs to the industry standard protocol. Adding these two elements to a test not only increases test fault coverage, but also creates a more robust and reliable test by incorporating additional aspects of the board in the test.
onTAP’s TestGen screen provides almost unlimited capability to shape and customize test plans, in addition to providing traditional pre-set test generation. Modern applications such as the popular Broadcom communication devices that support IEEE 1149.6 AC testing, often require insertion of custom initialization scans which TestGen now accomplishes in a direct manner, as the image below demonstrates.
Inserting an External File into the Test Plan:
External text files containing SVF or DTS cluster instructions can be inserted into a TestPlan. They will appear in the compiled SVF at the position that they are dropped in the TestPlan. The procedure is:
- Drag and drop, External File Name or SVF, into a position on the TestPlan.
- Click on the inserted instruction and then add a filename in the Options Edit box. The filename must be enclosed in quotes.
onTAP® Boundary Scan Requirements
In order to develop a project with onTAP Software, you will need the following:
BSDL Files for the devices to be tested
(BSDL = Boundary Scan Description Language) Most BSDL files can be found on the Manufacturer’s web site. Should you encounter difficulty obtaining a file, feel free to contact us at email@example.com. We would be happy to look through our archives.
Board Level Netlist files
A netlist file is the PCB’s roadmap and it is a very important piece of information for onTAP. The netlist file tells onTAP what the device types are, the circuit locations and their pin-to-pin connections. onTAP uses the BSDL files and your board netlist file to automatically create boundary scan tests. This includes infrastructure tests, interconnect tests and memory/cluster tests. Most often, the netlist file will accompany the PCB. In instances where the netlist file does not accompany the board, you should contact the board designer and ask for the netlist file in one of the many CAD formats that onTAP accepts. To view a listing of accepted CAD netlist formats, please follow this link: https://flynn.com/ontap-supported-netlist-readers-2
Evaluating a Boundary Scan Project
When you have the required information (BSDL files and Board Netlist Files) and if you would like assistance from us, you may send that information to firstname.lastname@example.org . We will review your application and consult with you as to what configuration of onTAP you will need.
