    f.writelines(width.format(*title))

    for item in data:

使用ElementTree處理stack.xml

以下包含xml建立，讀取，改寫，存檔等動作：

import xml.etree.ElementTree as ET
tree = ET.parse('d:/demo/stackup1.xml')
x = tree.getroot()


y = x.find('./Stackup/ELayers/Layers')
for child in y:
    print(child.get('Elevation'))
    child.set('UnionPrimitives', 'true')
    child.set('Material', 'Copper')
tree.write('d:/demo/stachkup2.xml')

計算選取物件的XYZ邊界

 選擇多個物件，執行下面script，即可輸出選取物件的XYZ邊界座標。

import ScriptEnv

ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oProject = oDesktop.GetActiveProject()
oDesign = oProject.GetActiveDesign()
oEditor = oDesign.SetActiveEditor("3D Modeler")


def setModel(x):
    objs = {True: [i for i in x if x[i]], False: [i for i in x if not x[i]]}
    for b, o in objs.items():
        if o:
            oEditor.ChangeProperty(
                [
                    "NAME:AllTabs",
                    [
                        "NAME:Geometry3DAttributeTab",
                        [
                            "NAME:PropServers",
                        ] + o,
                        [
                            "NAME:ChangedProps",
                            [
                                "NAME:Model",
                                "Value:="  , b
                            ]
                        ]
                    ]
                ])

def getBoundingBox(objs):
    db = {}
    for i in range(oEditor.GetNumObjects()):
        name = oEditor.GetObjectName(i)
        p = oEditor.GetPropertyValue('Geometry3DAttributeTab', name, 'Model')
        db[name] = p

    setModel({i :(i in oEditor.GetSelections()) for i in db.keys()})
    result = oEditor.GetModelBoundingBox()
    setModel(db)
    return result

size = getBoundingBox(oEditor.GetSelections())
AddWarningMessage(str(size))

HFSS 3D Layout當中找出互連的物件群組

分層找出物理上互連的物件群組，針對沒有netname的物件也可以使用。這裡用到遞迴的函數。

import json
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oProject = oDesktop.GetActiveProject()
oDesign = oProject.GetActiveDesign()
oEditor = oDesign.GetActiveEditor()

objdic = {}
for layer in oEditor.GetStackupLayerNames():
    objdic[layer] = oEditor.FilterObjectList('Type', '*', oEditor.FindObjects('Layer', layer))

result = {}
for layer in objdic:
    for obj in objdic[layer]:
        poly = oEditor.GetPolygon(obj)
        x = oEditor.FindObjectsByPolygon(poly, layer)
        if len(x) > 1:
            result[obj] = x

def getConnect(key, g):
    for i in result[key]:
        if i not in g:
            g.append(i)
            getConnect(i, g)
        else:
            continue
    return g

group = []
for obj in result:
    x = getConnect(obj, [])
    if sorted(x) not in group:
        group.append(sorted(x))

with open('d:/demo/connect.json', 'w') as f:
    json.dump(group, f, indent=4)

(圖一)輸出互連狀況

如何背景執行Python檔

如果我們想執行一隻Python程式，不會跳出任何視窗，只在背景模式執行，比方說監控電腦狀態並輸出log檔，可以使用pythonw.exe搭配start，就不會跳出任何視窗，範例如下。

test.bat

path=D:\myvenv\Scripts
start pythonw .\test.py

test.py

import os
import time
os.chdir(os.path.dirname(__file__))

while True:
    with open('test.log', 'a') as f:
        f.writelines(str(time.time()) + '\n')
    time.sleep(1)

進一步我們可以將該程式(.bat)設定為開機執行。選擇該程式並按Windows鍵+R，跳出下面視窗再按確定即可。
