Modify the deisgn and platform config files to set different core utilization, clock period, place density, etc.\n2. Create NUM_PROCESS different Makefiles.\n3. Start NUM_PROCESS jobs.\n4. Collect results/logs/reports/objects/designs folders, the pdn.cfg and the config.mk files in a data folder.\n\nCurrently, the run_design.py can use LHS method to generate random data points, and the following parameters can be swept using the script.\n\n```\nCLK_PERIOD  \t\t- constraint.sdc in designs\nCORE_UTILIZATION \t- config.mk in designs\nASPECT_RATIO \t\t- config.mk in designs\nPLACE_DENSITY    \t- config.mk in designs\nGP_PAD\t\t\t- config.mk in platforms\nDP_PAD\t\t\t- config.mk in platforms\nFLATTEN \t\t- synth.tcl in scripts\nABC_CLOCK_PERIOD \t- synth.tcl in scripts\nPINS_DISTANCE\t\t- io_placement.tcl in scripts\nCTS_CLUSTER_SIZE \t- cts.tcl in scripts\nCTS_CLUSTER_DIAMETER \t- cts.tcl in scripts\nLAYER_ADJUST \t\t- fastroute.tcl in platforms\nGR_OVERFLOW \t\t- fastroute.tcl in platforms\n```\n\nDifferent adjustment values can be applied to separate layers in **LHS_ATTRS** in the following way:\n```\n\"LAYER_ADJUST\":         ['uniform', 0.1, 0.7],    - default range\n\"LAYER_ADJUST_met1\":    ['uniform', 0.2, 0.4],    - range for met1 only\n\"LAYER_ADJUST_met2\":    ['uniform', 0.5, 0.6],    - range for met2 only\n```\n\nThe genMetrics_bigDoE.py script extracts tns/wns/power values from designs' reports swept by run_design.py. The Big-DOE-plots.ipynb is used to plot figures/distributions within Jupyter Notebook.\n\nA clean_doe taget is added at the end of the Makefile to delete files/folders from the previous runs\n```\nclean_doe:\n    rm -rf  ./data\n    rm -rf ./designs/*/*parallel*\n    rm -rf ./*/process*\n    rm -f Makefile_process*\n    rm -rf ./doe_reports\n    rm -f ./platforms/sky130hd/config_*\n    rm -f ./platforms/sky130hs/config_*\n    rm -f ./platforms/sky130hs/fastroute_*\n    rm -f ./platforms/sky130hd/fastroute_*\n    rm -f $(SCRIPTS_DIR)/cts_*.tcl $(SCRIPTS_DIR)/synth_*.tcl $(SCRIPTS_DIR)/global_route_*.tcl\n    rm -f doe.log\n```\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmsaligane%2FBig-DoE-OpenROAD","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmsaligane%2FBig-DoE-OpenROAD","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmsaligane%2FBig-DoE-OpenROAD/lists"}
