Abstract :
This paper presents a new pyramidal architecture FPGA intended for fast dynamic configurations (PARC) and highly efficient medium design implementation. This device consists of a large number of fine-grained arrays of optimized heterogeneous logic blocks and a new pyramidal structure with three hierarchical levels. In addition, either logic blocks and/or I/O blocks are simplified in order to highly accelerate the routing process which is performed by a controller. The PARC device is a reprogrammable SRAM based product developed with Synopsys design automation CAD tools, using VHDL and the 0.8 μm BiCMOS cell library from Nortel, to operate at a 50 MHz clock frequency. These various features allow for very fast routing-speed improvement when compared to the XC4003A from Xilinx company
