Ok, I'm a beginner in VLSI. I'm using Skywater 130 and I use Xschem and magic for layout. In Skywater 130 the minimum dimension is 0.15um (150nm), but...can I to use any dimension highter? I thought I had to use integer multiples of 150 nm, but apparently XSchem does not report errors if, for example, I use an L equal to 3.3. I also thought I had to refer to the Lamba rules (in this case lambda = 75) but it does not seem to be so. The same thing goes for the W dimension; apparently the minimum is 350nm, but can I use any other higher dimension and do I have to refer to multiples in this case too? Thanks for your answers.

The sky130 process is not limited by lambda rules. You can design with any dimensions, as long as its larger than the minimum dimensions.

Thanks! You can confirm that minimum W/L dimensions are 350/150 nm?

It depends on the device type, but for the 1.8v nFET and pFET devices, the minimum dimensions are W=0.42um and L=0.15um. Shapes must be on-grid, so dimensions must be multiples of 5nm. Practically speaking, widths should be kept to a maximum of around 10um or so; for larger widths, use multiple devices in parallel
