Library issues in the implementation of fast R2W converters

Properly choosing tire type and functionality of the cells being included in a technology library is essential to obtain efficient physical-level implementations of digital circuits; this is particularly true when the circuits are characterized by asymmetric logic structures and unbalanced input-to-output paths. In this paper, we report the results of an exploration we have conducted on the implementation of a high-throughput R2W conversion unit using a variety of libraries. Such results are exploited to assess advantages and drawbacks of the considered libraries.
