| # POST-INIT PLUG-IN |
| #################################################################################### |
| # |
| # This plug-in script is called after design import from the run_init.tcl script. |
| # |
| # -------------------------------------------------------------------------------- |
| # Can be used for various floorplan related tasks, like: |
| # - Die/core boundary |
| # - placement of hard macros/blocks |
| # - power domain size and clearence surrounding to it |
| # - Placement and routing blockages in the floorplan |
| # - IO ring creation |
| # - PSO planning |
| # -------------------------------------------------------------------------------- |
| # Specifically, this example includes tasks related to the LP/CPF foundation flow |
| # including power domain modification and power shut-off planning. The examples |
| # included here operate based on variables (vars array) defined in the |
| # OVERLAY/lp_config.tcl file |
| # |
| #if {[info exists vars(cpf_file)]} { |
| |
| # -------------------------------------------------------------------------------- |
| # Modify power domains |
| # -------------------------------------------------------------------------------- |
| # The 'modify_power_domains' procedure is included with the foundation flows |
| # to help automate power domain modification. To enable this, please set the |
| # appropriate variables in the lp_config.tcl and uncomment the following command |
| # |
| |
| # ::FF_EDI::modify_power_domains |
| |
| # -------------------------------------------------------------------------------- |
| # Power switch insertion |
| # -------------------------------------------------------------------------------- |
| # The 'add_power_switches' procedure is included with the foundation flows |
| # to cover common power switch insertion scenarios. To use, set the appropriate |
| # variables in the lp_config.tcl file and uncomment the following command. |
| # -------------------------------------------------------------------------------- |
| # NOTE: This procedure will NOT COVER THE ALL THE OPTIONS in addPowerSwitch |
| # For more complicated scenarios, please manually add the addPowerSwitch command |
| # here with the necessary options. |
| # -------------------------------------------------------------------------------- |

| # ::FF_EDI::add_power_switches |
