If I create a spice netlist out of xschem, I can import it in magic. All the premitive and stcell devices are visible in the layout. Then I connect them properly and get the .mag and the .gds files. I have created 2 such basic circuits and their layouts. Now I have created a third circuit where the 2 basic analog blocks are instantiated. I have created the spice netlist of it. Now, when I import this netlist in magic, only the ports of the 2 basic circuits are visible. Not the complete layout of them. What should I do so that my basic layouts behave like stdcells? @Tim Edwards
