#626 Macro hardening failed at final routing New issue created by vijayank88 Description I am trying to do macro hardening for riscv_core. Same riscv_core I'm able to complete gds2 generation in 20min using OpenRoad-flow-scripts. But in openlane flow got stopped at final routing stage after 65Hrs time. logs shown at the end Environment • Operating System Information:

uname -a

Ubuntu 20.04 • Docker Version:

docker --version

20.10.8, build 3967b7d • OpenLane Tag in use:

python3 ./dependencies/get_tag.py

in the main OpenLane directory. 2021.09.23_03.17.13 Reproduction Material • Find the below link to download source files. riscv_core.zip https://github.com/The-OpenROAD-Project/OpenLane/files/7236267/riscv_core.zip • List the commands used to run the design. Inside Openlane directory $make mount $./flow.tcl -design riscv_core Expected behavior Lesser run time and complete the flow without routing violations error. Logs
