This post is about the term "Retarget" and how that relates to P2654, P1687.1, 1687, and 1149.1-2013.
From IEEE Std 1687-2014:
Device: A collection of circuitry with a well-defined test boundary, generally including a TAP and physical pins.
From IEEE 1450-1999:
Device: A reference to an integrated circuit or other design structure.
From IEEE P2654 Working Group discussion:
Louis: 1687 definition is closer for us
Ian: TAP needs to be clarified as it doesn’t really apply to STAM
Ian: Conventional usage associates TAP with JTAG. Needs to be generic Test Access Port (which could be I2C or SPI)
