| Summary: | 碩士 === 國立成功大學 === 電機工程研究所 === 84 === We will compare flexibility for different segmented routing
structures of FPGA. They are implemented by antifuse
programming technology. They will be compared under same area
and performance. We first state out the comparison method which
strictly defines the factors of technology and architecture.
Then some typical topologies of segmented routing structure are
systematically investigated. At last flexibility comparison is
performed theoretically. The flexibility criterion is based on
partitioning of segments and calculated by enumeration theory.
Consequently, some commonly seen routing structures such as row-
based type, symmetrical-array type and hierarchical type are
compared. To complete the theoretical study about FPGA in this
thesis, the discuss of routability for row-based FPGA with
segmented routing channel in [Pedr94] is introduced at the
final chapter. This paper is so significant that we treat it as
fundament of theoretical routability study.
