openlane has FP_ASPECT_RATIO. which is defined in the docs as The core's aspect ratio (height / width). As I want it taller rather than wider, I choose 2. Then the tools fail because apparently it can only be 0 -> 1. So is there any way of getting taller?

What openlane commit corresponds to docker image

efabless/openlane:rc5

? I'm using the

master

commit, but get the following when running

flow.tcl

spm

Copy code

Error: or_ioplacer.tcl, 36 invalid command name "ioPlacer::set_random_mode"
[ERROR]: during executing: "openroad -exit /openLANE_flow/scripts/openroad/or_ioplacer.tcl |& tee >&@stdout /openLANE_flow/designs/spm/runs/cvc1/logs/floorplan/ioPlacer.log"

I feel that this has been discussed before, but I couldn't find the thread.

[caravel] what is the point of the

interactive.tcl

script in the

user_project_wrapper

openlane config?

Jecel Assumpção Jr

flow.tcl checks for its presence and calls it instead of config.tcl

The problem I am having is that opentriton gets into an infinite loop trying to read

/project/openlane/user_project_wrapper/runs/user_project_wrapper/tmp/merged_unpadded.lef

to do the detailed routing, even though magic can read that file just fine (it takes about 27 seconds)

Copy code

The only place this could happen given what it printed and what it didn't would be inside `lefyyparse` from <https://gitlab.lip6.fr/vlsi-eda/coriolis/-/blob/devel/lefdef/src/lef/lef/lefrReader.cpp>

this is what magic thinks of the file (plus the .def file that OpenTriton doesn't get around to reading)

#128 Sphinx + ReadTheDocs build setup Pull request opened by wgryncewicz This PR creates basic config for automated documentation build/publish using Sphinx and RTD. As the documentation is in markdown,

recommonmark

was used for compability. Solves #127 The RTD preview is currently available here: https://openlane-docs.readthedocs.io/en/rtd-w-markdown/ Currently recognized issues: •

recommonmark

does not support tables. This was patched by

sphinx_markdown_tables

extension, but some tables still did not render. • static image paths in MD are not linked properly in HTML • documentation points to some code files, such as

.cfg

.tcl

. These are not linked in HTML. efabless/openlane Travis CI: Build Created

Hi everyone! I asked this already in #general and was redirected here, so here is my question again: I have a problem with OpenLane and building a VERY small example. It fails with an error message during "Generating PDN" process. The log is attached. The two core error messages are "Error: cannot open '/.openroad'." (which seems to be normal) and "Unexpected error: can't read "stripe_locs(met4,GROUND)": no such element in array". I tried the process using these two guides:

https://www.youtube.com/watch?v=d0hPdkYg5QI▾

https://inst.eecs.berkeley.edu/~cs250/fa20/labs/lab1/ Both fail with the same error. However, the "make test" worked flawlessly. What I basically did: $ flow.tcl -design my_design -init_design_config Edit designs/my_design/src/my_design.v (see attached file) $ flow.tcl -design my_design Any suggestions?

pdn.log my_design.v
