XJTAG delivers a diverse range of
boundary scan test solutions for clients across a wide range of industries, including aerospace, automotive, defence, medical, manufacturing, networking, and telecommunications.
Acculogic, for example, will likely highlight its line of
boundary scan test tools--including the ScanNavigator integrated
boundary scan test environment--which can be used throughout the product life cycle from design verification and validation and continuing into pilot production and manufacturing and onto field service and repair.
The TAP controller state diagram shows the sequence of any
boundary scan test through the TAP controller, and applies to components that comply with IEEE 1149.1.
Designed specifically for Teradyne by JTAG, the solution with an advanced
boundary scan test option is for manufacturers using the company's TestStation and GR228X family of In-Circuit Test systems, it said and added that two implementations of Symphony are supported by this collaboration for highest production test flexibility.
(2.) Test needs the netlist for
Boundary Scan Test purposes only (3.) If OBD++ is provided the gerber is not required.
Keysight Technologies announced in March that SSP has achieved significant
boundary scan test capabilities using the Keysight x1149 boundary scan analyzer in a standalone configuration or integrated with the Keysight i3070ICT system.
* Boundary scan interconnect and buswire test:
Boundary scan test for interconnect pins between boundary scan devices.
Boundary scan requires the IC designer to dedicate four or five physical pins, 200 gates of silicon and write
boundary scan test code for the IC.
The key is how to put a process in place in the PCBA production cycle to ensure the possibility of a non-working or unstable
boundary scan test is minimized or completely eliminated during production testing.
Indeed, in-circuit test equipment makers consider boundary scan to be a complementary technology, and in fact, Chari at Agilent said, "
Boundary scan test is a subset of ICT technology." Boundary scan, he noted, is available as part of an in-circuit system or independently.
