Schedule important than QOR for NL before FINAL netlist Project management must decide on acceptable quality level for each NL Scan team start setup of DFT parameters at project / tile level Work/debug with tile owners / FEINT team during regression $FLOW_DIR/$FAMILY - TileBuilder/supra All files under actions, templates, scripts - owned by CAD team Params under params/project, params/tile - owned by project team $ALLTILES_DIR - tune / other data All tunables and data files – owned by project team $AMD_STEM (equivalent to $STEM) – design data RTL snapshot containing VF and other data files – owned by design team Supra components Targets: CSH scripts that invoke EDA tools or scripts TileBuilder/supra/actions/dft/… Templates: mostly TCL scripts with Embedded Perl TileBuilder/supra/templates/dftadvisor/… Scripts: in-house scripts, too complicated for CSH, can be called by Targets and/or Templates, as appropriate TileBuilder/supra/scripts/dft/… Parameters: similar to environment variables, which Control the flow of targets (some on, some off) Control the contents of Comm
