Summary:Recently, designers have been embedding reusable modules to build
on-chip systems that form rich libraries of predesigned, preverified
building blocks. These embedded cores make it easier to import
technology to a new system and differentiate the corresponding product
by leveraging intellectual property advantages. Most importantly, design
reuse shortens the time-to-market for new systems. The attributes that
make system chips built with embedded IP cores an attractive
methodology-design reuse, heterogeneity, reconfigurability, and
customizability-also make testing and debugging these chips a complex
challenge. The authors review the various alternatives for testing
embedded cores and describe solutions and proposed standards that are
expected to play a key role in developing the core based design paradigm
