| Example usages with TCL interpreter |
Open the TCL interpreter for PDNSim.
$ pdnsim
Run the following TCL commands:
PDNSim pdn
pdn import_lef /path/to/lef/file.lef
pdn import_def /path/to/def/file.def
pdn import_verilog /path/to/gate-level/netlist/file.v
pdn set_top_module moduleName
pdn import_sdc /path/to/constraints/file.sdc
pdn import_lib /path/to/liberty/file.lib
pdn read_voltage_src /path/to/Vsrc.loc
pdn analyze_power_grid
The analyze_power_grid command supports the following optional arguments: analyzer_power_grid -layer -net VDD/VSS
analyze_power_grid -layer M1 -net VSS
| Argument | Comments |
|---|---|
| layer | Reports the worst case IR on the specifed layer and plots the IR map (optional, str) |
| net | Specifies which net to analyze: VDD/VSS (optional, str) |
If the above two arguments are not specified, the default arguments are net VSS and layer 1.
