We have developed the via-programmable logic device VPEX which was optimized for EB direct writing, and also developed the dedicated CAD system for the VPEX. The VPEX logic element composed of complex-gate type exclusive OR gate and inverters can be configured to one of 2-input logic functions or 3-input logic functions such as AOI and multiplexer with via-1 layer. The routing between LEs can be programmed by the via-3 layer which change connections between fixed metal-3 and metal-4 layers. Thus, the routing architecture and routing resources of each LE affect the wiring success ratio greatly. In this paper, we examine several routing architectures to improve the routability. |
