use too much memory

Hi,

I just tested the code with a .kicad file, the circuit is simple, it contains 12 nets and 2 layers. It used a lot of memory (more than 60G) and my computer can not finish running on testcase because it has no enough memory and the program is killed. So is that normal?

Here is a screenshot of the results:

Hi - unfortunately the original authors of the routing algorithm have graduated several years ago. The router is memory intensive, but one possible remedy is to coarsen the routing grid scale from the default. It should be the first top-level argument.
