BSDL Verification

IEEE Std 1149.1 requires that vendors of JTAG / boundary-scan compliant devices provide so called BSDL files. BSDL (Boundary Scan Description Language) files yield details about the test resources implemented in such a device and are used by practically all boundary-scan tools.

 

Even though most BSDL files are correct these days, there is always a chance for a syntax error or, worse, a description error (for example a specification of fewer boundary-scan cells than physically implemented in the chip, wrong instruction op-codes, or a wrong order of boundary-scan cells). The execution of boundary-scan tests that have been generated based on incorrect BSDL files will result in false diagnostics and, in the worst case, has potential to cause damage on the Unit Under Test.

 

GOEPEL offers BSDL verification tools (TAP Checker and BSDL Syntax Checker) as well as BSDL verification services.
