| Foundation Flows |
| ---------------------- |
| |
| The scripts provided here are intended to be used by Cadence AEs as the starting |
| point for assisting customers in building an implementation environment for |
| Innovus. They provide a working example containing guidelines and recomendations |
| for command sequences and options. Some customization is expected as each customer |
| and design will have unique requirements. The goal was to capture a general methodology |
| from which to build upon. |
| |
| ------------------------------------ |
| |
| The foundation flows reside in the SCRIPTS directory (created by writeFlowTemplate). |
| This directory can be renamed and/or moved but the contents within the SCRIPTS |
| directory must remian unchanged. The scripts directory is accessed by the |
| variable "vars(script_root) <path>" in the setup.tcl. |
| |
| The setup.tcl is the main input file to the foundation flow. It defines all |
| the input data required to run each of the foundation flows. |
| |
| Additionally, an innovus_config.tcl must be created to set flow variables, |
| desired command options, and optional plug-ins. |
| |
| Finally, for LP/CPF flows, an additional config file (lp_config.tcl) can |
| optionally be used to help automate some low power related tasks. |
| |
| ------------------------------------ |
| |
| The TEMPLATES directory contains templates for all of these files which can |
| be manually copied and edited: |
| |
| TEMPLATES/INNOVUS/setup.tcl |
| TEMPLATES/INNOVUS/innovus_config.tcl |
| TEMPLATES/INNOVUS/lp_config.tcl |
| |
| There is also a utility that can be used to generate these files based on |
| existing design data. To generate, run Innovus, load an initial database, |
| and 'source SCRIPTS/gen_setup.tcl' or run the new command generateFFSetupFile. |
| |
| This will generate a *.auto.tcl files which can be reviewed/edited |
| and then renamed. |
| |
| ------------------------------------ |
| |
| The EXAMPLES directory contains some example configuation files as well as |
| some sample plug-ins. Please check README in the EXAMPLES directory to run the example. |
| |
| ------------------------------------ |
| |
| To generate the foundation flow scripts based on your setup , do the following: |
| |
| tclsh <path_to>/SCRIPTS/gen_flow.tcl -m <flat | hier > <steps> |
| |
| where <steps> = single step, step range, or 'all' |
| |
| To execute the flow, run 'make <target>' |
