Evaluation results of Antifuse type FPGA

Autor: Yamada, Noriko, Shindo, Hiroyuki, Kuboyama, Satoshi, Matsuda, Sumio

Several failures of a new generation of Antifuse type FPGAs (RTSX-S, SX-A) were reported subsequent to successful programming in the U.S. in 2003. It was inferred that the degradation of Antifuses causes the signal delay after the investigations and
