Here we provide scripts to run DCTopo. DCTopo requires milkyway (mw) library (contains physical information of the standard cells and macros). Also, DCTopo uses *.db file. So we provide the following scripts to run DCTopo:
- gen_lib.sh: This script runs the library compiler to generate a .db file from a .lib file. This uses the gen_lib.tcl file. You have to provide the .lib path, library name and the output .db directory path.
- gen_mwlib_from_lef.sh: This script generates milkyway library from the *.lef file. Milkyway libraries provide physical information of standard cells and macros in the DCTopo flow. It uses gen_mwlib_from_lef.tcl script, which reads the technology .lef file and the standard cell / macro .lef and writes out the milkyway library of the corresponding standard cell / macro. Also, this scripts writes out the *.tf file, which is equivalent to tech .lef file.
- run_dc_topo.sh: This script runs DCTopo. It uses run_dc.tcl, which requires *.db (gen_lib.sh provides detailed steps to generate *.db from *.lib), mw library (gen_mwlib_from_lef.sh provides detailed steps to generate mw libraries from *.lef), *.tf (gen_mwlib_from_lef.sh provides detailed steps to generate *.tf from *.lef), *.def (floorplan def file contains only pin locations), *.sdc (timing constraints file) and Verilog files.
