Hi, I am getting this error while hardening the user project wrapper. Any insights into this error?
m
can you successfully harden a demo design like spm?
a
Yes
m
post your repo
a
m
and what command do you run that results in the error?
a
It is this command: 
run_power_grid_generation
m
can you give more info
I've never seen that command used before
is it inside openlane docker?
pls provide all the commands you run
you should try to make it easy for people to help you - provide all the info they need to reproduce the problem. Then you're more likely to get help
a
Sure, I am using these commands inside docker: 
verilog_elaborate
init_floorplan
place_io_ol
add_macro_placement mprj 360 300 N
manual_macro_placement f
run_power_grid_generation
write_powered_verilog -power vccd1 -ground vssd1
set_netlist $::env(lvs_result_file_tag).powered.v
global_routing_or
detailed_routing
run_magic
run_magic_drc
So run_power_grid_generation, helps establish the multiple power grids required for the wrapper.
m
Why aren't you using make user project wrapper?
a
I tried hardening the wrapper using 
make user_project_wrapper
command from within the caravel_user_project repo and I am getting a version mismatch warning.. Can this be a possible reason for the error?
m
Yes I would definitely fix that
Then use the makefile
I will try your designt tomorrow
a
I tried to get the desired version for the shuttle, but I am not able to get the correct tags somehow..
Sure. Thanks!
m
Wipe out your old pdk and openlane completely
Then follow the instructions in caravel user project exactly
a
Sure. Got it!
m
it fails for me too
I think your problem is that your gds is too large and already has power rings
i would re-harden it with the new tools
but you should be aware that the cts issue will also affect your design
so you should wait until the fixed tools are released, then reharden
make sure no power rings, set as no-core
then add to caravel
a
Right Got it. I would retry with the updated tools.
