电打火控制芯片电压功能模块版图的优化设计

Optimizing Design on Voltage Function Module Layout of Electronic Ignition Controlling Chip of Car

针对电打火控制芯片的版图设计中有部分器件没有达到最小尺寸的情况,研究了将原版图缩小的方法.文中以电压功能模块为例,说明了此种方法,并进行了设计规则检查,在整体版图优化设计后进行了网表一致性检查,最后进行流片.结果表明,对电打火控制芯片原版图的缩小是切实可行的.通过对版图的缩小以及对器件重新优化布局规划,使芯片面积大大缩小,从而降低了设计成本,减少了器件的功耗.

A course in detail on having some devices that dont receive lest rules in layout design of electronic ignition controlling chip is researched to shrink the original layout. The layout of voltage function module is shrunk in this way for example. Furthermore, it passes design rule checking （DRC） and after the whole redesign is accomplished, it runs layout versus schematic （LVS）. The tapeout result displays that it is feasible to shrink the original layout. With the rules of devices shrinking and devices floorplan optimized, the chip area is shrunk greatly, the price of design is reduced and the power dissipation is reduced.
