如何在HFSS當中將物件以netname命名

從3D Layout匯出HFSS，HFSS物件的名稱為層數及編號。用net命名更加清楚，底下兩組腳本可以用來完成重新命名的工作。

在3D Layout執行，從3D Layout輸出座標訊息到rename.json檔案當中。 

Rename_Net_1.py

import ScriptEnv
import json, os
from collections import OrderedDict

ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oDesktop.ClearMessages("", "", 2)
oProject = oDesktop.GetActiveProject()
oDesign = oProject.GetActiveDesign()
oEditor = oDesign.SetActiveEditor("Layout")
os.chdir(os.path.dirname(__file__))
db = {}
layerinfo = OrderedDict()
lower_elevation = 0
for layer in oEditor.GetStackupLayerNames()[::-1]:
    info = oEditor.GetLayerInfo(layer)
    layer_thickness = float(info[12].split(':')[1])

    layerinfo[layer] = lower_elevation + layer_thickness / 2
    lower_elevation += layer_thickness
    db[layer] = []

    for i in oEditor.FindObjects('Layer', layer):
        otype = oEditor.GetPropertyValue('BaseElementTab', i, 'Type')
        if otype in ['Pin', 'Via']:
            location = oEditor.GetPropertyValue('BaseElementTab', i, 'Location')
        elif otype in ['line', 'poly']:
            location = oEditor.GetPropertyValue('BaseElementTab', i, 'Pt1')
        else:
            continue

        x, y = location.split(',')
        net = oEditor.GetPropertyValue('BaseElementTab', i, 'Net')
        db[layer].append((x.strip(), y.strip(), net, otype))

with open('rename.json', 'w') as f:
    json.dump((layerinfo, db), f, indent=4)
    AddWarningMessage('Completed!')

在HFSS執行，讀取rename.json完成重新命名工作
