Multiple cells with name: FGCCTE in GDSII file about gdspy

[heitzmann]

Instead of reading into the same library, you can add individual cells and overwrite any duplicates (assuming cells with the same name in both libraries are identical, there should be no problem), for example:

lib1 = gdspy.GdsLibrary(infile ='dev1.gds')
dev1 = lib1.cells['dev1_main']

lib2 = gdspy.GdsLibrary(infile ='dev2.gds')
dev2 = lib2.cells['dev2_main']

lib = gdspy.GdsLibrary()
lib.add(dev1)
lib.add(dev2, overwrite_duplicate=True)

main = lib.new_cell('main')
main.add(gdspy.CellReference(dev1, (0, 0), magnification=1, rotation=0))
main.add(gdspy.CellReference(dev2, (0, 0), magnification=1, rotation=0))

lib.write_gds('main.gds')

It works now. Thank you so much, Heitzmann! You are super brilliant！！
