Hi, I tried to run a post-layout (with RC extraction) simulation but I got an error due to mosfets that has w = 0 l = 0 in the netlist. How can I resolve this problem?

You have 4 mos fets extracted - XXM1, XXM2, X0, X1. Is that what you're expecting? Maybe flatten

sky130_fd_pr__pfet_01v8_7P3MC

and

sky130_fd_pr__nfet_01v8_BXYDM4

first.

Thanks for the reply, but there are two mosfets in my layout. Why are four mosfet extrated by magic? And how I flatten this cells?

You're working directly with magic data, correct? Not importing GDS, right?

yes, this is my layout

1. Try newer magic versions. Had same bug

My magic version is 8.3 revision 266. İs there any newer version than this?

@User I've never used it myself, but it looks like there's a

flatten

command in magic. You might try that.

I tried to use this command but nothing has changed.

You checked why is it outputing "bad devices"?

I couldn't find extresist log but one of the point of bad devices is here.

How about selecting the subcell with

s

and then in the command window

what

to make sure just the cell is selected

select flat

to select all the layers in the subcell

copy left 0

to copy to the current cell

select clear

to clear the selection reselect the subcell in the layout window with

s

what

in the command window to be sure

delete

to delete the subcell. magic creates devices as you paint them, so you shouldn't be able to see poly over diffusion. Maybe that's where the bad device is being detected. In the future, maybe try

dump <cell>

when placing primitives.

Thanks @User , these solved my problems. I just added the "select area" command. How about selecting the subcell with

Hi, You know, How Can I run a post- layout?

How about this https://skywater-pdk.slack.com/archives/C016HUV935L/p1619055439178200

Yes I have that file and a file of Netlist of xschem and I ran LVS and that was correct but i don't know how can I simulate a post layout

Can you swamp swap your schem netlist with your extracted netlist? Make sure the pins are in the same order.
