Logical & physical aware automatic solution for scan chain insertion of newly added registers in Conformal ECO

Abstract： With the scale of Digital IC increasing, ECO is more frequently and largely used during implementation flow. When hundreds of newly added registers are required, the manually insertion to exist scan chain for these registers is a big challenge for engineers. This paper describes an automatic solution for above problem with both logical and physical concerns, based on Cadence Conformal and Innovus. For logical part, the clock domain consistence is correctly obeyed. And for physical part, both longest scan chain length and Place&Route friendly requirement are covered well. Moreover, as the nature of automatic solution, hundreds of newly added registers could be inserted efficiently and safely during practice.
