私は回路図のネットリスト（サブサーキットのコレクション）を持っています。一般に、いくつかの SPICE シミュレーターによって作成されます。通常、階層があります（トップレベルのサブサーキットは、さまざまなサブサーキットを呼び出すかインスタンス化し、ピンを介してそれらの間の接続を定義します）。サンプル ネットリストは次のようになります。

subckt AN2D0 A1 A2 VDD VSS Z

    M_u2 (net5 A2 VDD VDD) pch 
    M_u1 (net5 A1 VDD VDD) pch 
    M_u3 (Z net5 VDD VDD) pch 
    M_u4 (net17 A2 VSS VSS) nch 
    M_u2 (Z net5 VSS VSS) nch 

ends AN2D0

subckt LS_RX_CONTROLLER VDD VSS burst_start_or_sys burst_start_out pd pd_pwm_det pd_pwm_det_TII std_by std_by_or_sys sys_en sys_out

    I2 (burst_start_or_sys std_by VDD VSS burst_start_out) AN2D2
    I1 (net22 std_by_bar VDD VSS sys_out) AN2D2
    I5 (net022 pd VDD VSS pd_pwm_det) OR2D2
    I10 (net026 pd VDD VSS std_by_or_sys) NR2D2
    I9 (sys_en std_by VDD VSS net026) NR2D0
    I6 (std_by VDD VSS std_by_bar) INVD0
    I3 (pd_pwm_det_TII net037 VDD VSS net022) OR2D0
    I11 (sys_en std_by VDD VSS net037) OR2D0
    I0 (burst_start_or_sys sys_en VDD VSS net22) AN2D0

ends LS_RX_CONTROLLER

これで、異なる階層で同じサブサーキットをインスタンス化できます。呼び出されるすべてのサブサーキットは、呼び出しサブサーキットの前に定義されます。この種のグラフは有向非巡回グラフと呼ばれます。スペースを節約するために、ネットリストから自己参照 HASH テーブルを作成しました。サブサーキットがサブサーキットのインスタンスを呼び出している場合、それはピンを指しています。最後の階層では、MOSFET D または S または G または B ノードを取得します (AN2D0 サブ回路が定義されているため)。いずれかのネット (インスタンスのピンへの接続) が階層 (net5 などのサブサーキットの呼び出しのみ) からサブサーキットを呼び出す親に持ち出される場合、それはピン (Z など) と呼ばれ、現在のサブサーキット定義行に常にリストされます。その名前で（subckt AN2D0 A1 A2 VDD VSS Z）。ハッシュのハッシュのハッシュを作成しました。

GRAPH --> subckt1--->p1
                     p2
                     net1
                     net2
          subckt2--->p1
                     p2
                     net1
                     net2
          subckt3--->p1 ---->I1.subckt1.p1--->pointing to value of p1 key of subckt1.
                             I2.subckt1.p2
                     p2
                     net1
                     net2

この後、任意のレベル階層からインスタンス化できるサブサーキット名と同じピンが与えられ、親を見つける必要があります。つまり、ネットがピンとしてプルアップされるまで親をトレースバックします。そして、すべてのリーフ (MOSFET D または G または S または B ピン) にストレスを与えます。

これに最適なアルゴリズムの種類と、それらを自己参照ハッシュテーブルに格納することが効率的かどうかを提案してください。

私の経験では、インデックス作成プロセスを使用してグラフ内のノードの一意の ID を生成し、次にキーがこの ID であるフラット ハッシュを作成することをお勧めします。IDを使用してリンクを作成します。例えば：

a => b、b => c、c => d、d => a

に変換します

%graph = ( a => { content => ..., linksto => [ b ] }, b => { content => ..., linksto => [ c ] }, c => { content => ..., linksto => [ d ] }, d => { content => ..., linksto => [ a ] } );
