The answer to these questions is an emphatic YES! Many silicon providers have included the P1687 architecture and are using both of the IJTAG languages, Instrument Connectivity Language (ICL) for describing the on-chip network and Procedure Description Language (PDL) for describing embedded instrument operations. So far, what’s been missing is public acknowledgement. It seems that many are waiting until the “P” for “preliminary” falls off the standard’s designation and the IEEE 1687 document is officially published before they “fess up” that they are, in fact, using it.
Be that as it may, a few early adopters have gone public and we, the IJTAG community, have managed to publish a paper or two. Most importantly, the imminent publication of the standard is leading to the emergence of an IJTAG ecosystem.
