@@garyhuang2742 I had to dos2unix the whole graywolf directory and also dos2unix everything in C:\cygwin64\usr\local\lib\graywolf\bin\flow otherwise it gave a reading syntax error when doing graywolf map9v3 the full dos2unix command was: find . -type f -print0 | xargs -0 dos2unix
Thank you for sharing your tips to get it work. I don't know why it would require to convert files from dos to unix format. But perhaps the text editor setting was set to save it in dos format?

Hi Gary, I am facing an issue post installation of graywolf on my Ubuntu 18.04 LTS. While trying to start graywolf by just typing graywolf, it is terminating abnormally with an error. Use of graywolf -d option says that its segmentation fault. Please can you help me with the resolution for this?
Graywolf expects a design with cell netlists and parameters (for instance circuit.cel and circuit.par) to be given when executed. If not, graywolf would terminate immediately with a syntax error and output messages on how to specify the command arguments. If there wasn't a circuit design, an example testing circuit may be cloned and checked out for testing at github.com/rubund/graywolf and change current directory to where the circuit is "cd graywolf/tests/map9v3" issue command "graywolf map9v3". That would do it.
Graywolf takes inputs circuit.cel and circuit.par. The circuit.cel contains cell geometry and circuit.par placement parameters. The circuit cells and parameters can be synthesized from verilog by qflow. Refer to video, IC Design EDA on Windows with QFlow uploaded on 2020-09-07 for details.
Graywolf can run individually, and the command to run is "graywolf circuit" where circuit is the circuit design containing circuit.cel and circuit.par. The resultant outputs of a simple design could be circuit.pl1 and circuit.pl2 where the circuit.pl1 contains the placement of cells, and circuit.pl2 contains the placement for cell rows and pads. For an overview of graywolf, there is a design document at opencircuitdesign.com/qflow/archive/TimberWolf.pdf where it has detailed information on the program functionality and the format of input and output files. Hope this information helps.
@@garyhuang2742 sir after executing yosys...i generated . Blif . Spice . V . Ilang But sir I'm little confused how we can use these files for graywolf....we aren't getting...tried every command on Ubuntu but we are getting error only
@@garyhuang2742 our task is to make qflow with our college standard cell but...sir is there any open source qflow where we can add our cell library...and all the tools remain same
wow ... after two days of debugging i could finally make graywolf simulate what you did in the video!!! Thank you for that trip!
Glad that you were able to make it work on your system. Great perseverance!

the full dos2unix command was:
find . -type f -print0 | xargs -0 dos2unix
i wonder why you didnt need to do that since we are both on windows?
