and `magic`: In xschem
, the total width of a MOS-FET is displayed on the symbol (plus the value of the multiplier), and to get the finger width one has to calculate indirectly by dividing the W by NF (NF is hidden in the properties dialog). In magic
in the MOS-FET p-cell, one has to enter the finger-width, plus NF and M. Maybe it is too late for this, but a harmonization would be good, to either enter finger width OR total width as W in both xschem
and magic
. Or maybe just add a comment in xschem that W is total width, and in magic p-cell dialog that Width is per finger.Akıner

(with .subckt and .ends lines commented). First approach makes the design self-contained (xschem files contain the netlist), second approach just links to the extracted netlist, so if you update the layout and re-extract the netlist subsequent simulations will use the updated netlist.Stefan Schippers

) for these standard cells (example: inv_2.sym
, nand2_1.sym
, dfrtp_1.sym
) there are no corresponding schematic files (.sch)
. Xschem when producing a netlist will just emit the subcircuit call (example: x8 Y VSS VSS VCC VCC net3 sky130_fd_sc_hd__inv_2
) , you must place a .include
line to load the corresponding netlist. In this case you must carefully ensure the port order produced by xschem matches the port order of the symbol netlist. In above examples the port order for the X
call and for the .subckt
definition are both generated by xschem so they match 'by design'.
