Hello, one question if I want to use the pdk capacitor for the layout, should I replace it in xschem with this same capacitor? Or is it enough that magic has the equivalent value? If so, is there a way to indicate that I will connect some in parallel or series? or should I draw each one individually in xschem

all devices on a sky130 project must map to existing silicon devices. For capacitors you must decide if you want to use MOS capacitors or MIM capacitors. MIM (Metal Insulator metal) are usually the best choice. You must set W and L and xschem shows the approximated calculated capacitance. for parallel you can set the MF parameter (multiplicity factor) or use vector instance name, like C1[9:0], representing 10 capacitor instances C1[9], C1[8], ..., C1[0]. For series connection there is no attomatic attribute, just draw the number of series caps.

thank
I did it like this, but I have a problem in magic, like not recognizing the vectorization when doing the layout

paste here the xschem netlist lines about the capacitor(s)
