Hi, I'm trying openlane for the first time and I am having a very basic issue

Thats the log. I created a design called test using

./flow.tcl -design test -init_design_config -add_to_designs -config_file config.tcl

And then created the following verilog file in the src folder

OpenLane Container (b6bacc9):/openlane$ cat designs/test/src/test.v 
module test (
    input  wire in,
    output wire out
  );

  assign out = ~in;
endmodule

OpenLane Container (b6bacc9):/openlane$

Why is open lane violating spacing rules and how do i change the config to prevent it from doing so? Thanks in advance

The design is too small for power delivery network. Try doing a bigger design or setting floorplan to "absolute" and die area to 300 x 300

also see the inverter example design

Thank you both for the suggestions. I will give that a try
