Using the current caravel model with an MPW-ONE design I now get 1000's of these messages! Ok it's moving cells, do I really need to know that much detail? 
. Moving to closest stripe at (21.840um, 5.400um).

Can I turn them off?

This was the topic of the previous thread. So far I've not managed to harden an mpw1 macro in mpw2. I reharden first in mpw2 tools.
j
This is building user_proj_example. Nothing hardened in it.
m
I don't understand your first post then. What is the mpw one design you mentioned?
j
Or, is it magically being hardened for inclusion in the wrapper.
Oh, it's the sha3 miner SoC.
m
Have you updated the configuration TCL file to include the power rails? Check the example designs in openlane. They all have a new config line
j
I've increased the die size in the user_proj_example/config.tcl. That's all.
Odd thing is, it's complaining about cells at negative coordinates!
m
Weird
j
This project https://github.com/miscellaneousbits/caravel_user_project.git will cause 100's of 1000's of these warnings!!!
Failing like this

@Jean You can disable this check by setting 
FP_PDN_CHECK_NODES
to 0. Make sure you are on v0.14/v0.15/mpw-two-b tag of openlane.
j
Ok, but why is it happening at all? Cell locations at negative coordinates doesn't sound good.
