Hello @User, @User, I was looking at the

sram_1rw1r_32_256_8_sky130_lp1.gds

in the caravel/gds/ directory and found out that there is a lot of empty space in the layout. Is there a way to measure this empty space?

Not sure what you want to measure. There are several ways to measure in magic. One is to place the "cursor box" on the outer boundary and then type the command "box", which gives you the dimensions and area. Then put the cursor box around the inner area and do the same. There is another command for measuring total metal density, but it sounds like you just want the dimensions?

@Aireen Amir Jalal: It also seems that you haven't run

expand

?

yes @Tim Edwards just the dimensions. Thanks I got it.

@Aireen Amir Jalal: It will replace the black box you see above with whatever is inside it. (http://opencircuitdesign.com/magic/commandref/expand.html)

Right. Just ran it and yes it makes sense! Thanks @Ahmed Ghazy
