An update on IEEE 1149.6 - successes and issues

This paper looks at IEEE 1149.6, two years after being approved as an IEEE standard. The paper was written based on: interviews with companies that have implemented IEEE 1149.6 (either in hardware or software tools), emails from the 1149.6 distribution list, working group meetings and previous papers. The paper begins with a review of the 1149.6 standard, including objectives of the standard and what the standard was not meant to do. It will then present some initial findings and concerns, prior to release of the standard. The paper also discusses the adoption of the standard and issues that have been discovered by companies trying to implement the standard
