luceda ipkiss教程 64：合并版图上的图层

案例分享：利用i3.merge_elements函数合并版图中的图层
如：

全部代码如下：

from si_fab import all as pdk
from ipkiss3 import all as i3
class MergeElements(i3.GDSCell):
    def _default_filename(self):
        return "demo.gds"
    class Layout(i3.GDSCell.Layout):
        def _generate_elements(self, elems):
            elems = super()._generate_elements(elems)
            return i3.merge_elements(elems, layers=[i3.TECH.PPLAYER.SI_CLADDING,i3.TECH.PPLAYER.SI])

if __name__ == '__main__':
    MergeElements().Layout().visualize()

代码中的demo.gds为教程19生成的gds，将gds和代码放同一文件运行就可以得到上图结果。
