Is there a way to get it to spit out intermediate routings?

This is probably not a great way, but what I do is use run_designs to iterate over some key variables, and then graph all the triton route timings

I would be most interested in GLB_RT_ADJUSTMENT, FP_CORE_UTIL and PL_TARGET_DENSITY

I just added plot_utils to my multi_project_tools and pushed it in case you want to try. It's pretty shonky (I've made no effort to make it more usable by other people), but it's pretty straight forward

In this case it was actually a bug (or a lack of understanding the parameters and their intended function). It seems to ignore PL_TARGET_DENSITY when PL_BASIC_PLACEMENT is set
