The structured ASIC on which the logic can be customized with a few mask layers, have been studied in order to reduce initial development cost including mask cost. We have been developed via-programmable logic device named VPEX, which can be programmed by 2 via layers. The logic element (LE) of VPEX consists of complex-gate type EXOR gate and NOT gate. In addition to
all 2-input logic functions, some 3-input logic functions such as AOI and multiplexer can be programmed by a single LE. The DFF can be configured by two LEs in the VPEX. Compared with other LEs such as 2-input LUT or SOP, the area and the delay of VPEX LE is as small as that of other LE, It is noted that the power consumption of VPEX is less than half of other 2-input LEs. In this paper, we report the logic-synthesized results of several benchmark circuits, in order to evaluate the area and the speed performance of VPEX |
