如何在HFSS當中快速設置差分對

在此範例當中，同一差分隊的同一側命名只有L跟H的差異，利用這一點可以使用腳本快速將所有符合規則的ports設置為differential pair。如果不是L跟H的差異，使用者可以修改腳本來適應命名規則。

DifferentialPairing.py

import ScriptEnv

ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oDesktop.ClearMessages("", "", 2)
oProject = oDesktop.GetActiveProject()
oDesign = oProject.GetActiveDesign()


def setdiffpair(i, p, n):
    result = [
        "NAME:Pair1",
        "PosBoundary:="    , p,
        "NegBoundary:="       , n,
        "CommonName:="    , "Comm_" + str(i),
        "CommonRefZ:="    , "25ohm",
        "DiffName:="      , "Diff_" + str(i),
        "DiffRefZ:="      , "100ohm",
        "IsActive:="      , True,
        "UseMatched:="    , False
    ]
    return result

oModule = oDesign.GetModule("BoundarySetup")
result = {}
for i in oModule.GetExcitations()[::2]:
    key = i.lower().replace('_l_', '').replace('_h_', '')
    if key not in result:
        result[key] = [i]
    else:
        result[key] += [i]

pairs = []
n = 1
for i in sorted(result.keys()):
    result[i].sort()
    if len(result[i]) == 2:
        pairs.append(setdiffpair(i, *result[i]))
        n += 1
        AddWarningMessage('{}, {}'.format(*result[i]))
    else:
        pass

oModule.EditDiffPairs(["NAME:EditDiffPairs" ,] + pairs)
AddInfoMessage("Differential pairing completed!")
