Abstract :
An SRAM-based FPGA architecture has been developed using a licensed AT6000 architecture base. The logic-cell architecture exploits an efficient, medium-grained, fixed library cell that implements most frequently used synthesis functions. An internal routing structure enables dense designs using a highly connected grid-based routing system and a dedicated I/O routing structure that supports the highest I/O counts available. Dynamic reconfiguration is retained with an underlying SRAM structure like the AT6000
