Everything You Need to Know About ScanWorks Interconnect Part 5: Operations of the TAP and the BC_1 Cell

Let’s continue with our example and see what happens after the EXTEST instruction is loaded, decoded, and the boundary scan register is configured between the TDI and TDO ports.

Everything You Need to Know About ScanWorks Interconnect Part 4: The Test Access Port (TAP) State Machine

Let’s dig a bit deeper into how the TAP works. The TAP provides 4 major operations within a boundary scan device.

IEEE 1149.1-2013: Excludable Segments

The 2013 Revision of the IEEE 1149.1 Standard incorporates support for dynamic data registers that can change in length and organization, unlike those fixed ones specified by the 2001 Revision. This allows, for example, definition of “excludable segments” for the boundary scan register (BSR); perfect for dealing with BSR segments in different power domains, some powered up and some not. How does this work?
