hspice pulse 在 有人問電路設計的步驟，和HSPICE裡面PWL使用方式 的推薦與評價
剛好有版友來信
我覺得可以波出來分享一下
有問題可以互相討論討論咩
: 再spectre的spwl裡面
: 好像沒有可以輸入Trise Tfall 的地方 hspice的指令也是 pwl (t1 v1 t2 v2.....)
: 我想你的意思 是要自己加上去再輸入到time2 time3 ...嗎?
對
如果是直接編輯netlist 再用hspice跑模擬
在netlist裡面打
Vinput net01 net02 pwl t1 v1 t2 v2 t3 v3 ...依此類推
^^^^^^ ^^^^^ ^^^^^
Vinput代表電壓源名稱
net01代表電壓源正端連到的net名稱
net02代表電壓源負端連到的net名稱
pwl代表這個電壓源使用piece-wise-linear方式敘述
接下來輸入一對一對的[time voltage] pair
假設你輸入的電壓波型可以用轉折描述
第一個轉折 1*T 0
第二個轉折 '1*T+Trise' VDD
第三個轉折 2*T VDD
第四個轉折 '2*T+Tfall' 0
第五個轉折 4*T 0
其中代入T=週期，Trise=上升時間，Tfall=下降時間，VDD=高電位
例：
Vinput_ptt net123 net456 pwl 0 0 1n 0 1.01n 2.5 2n 2.5 2.01n 0 4n 0
: 不然在轉則的地方還是會有3角型..
: 還有我查過資料都沒有說明
: https://www.wretch.cc/album/show.php?i=iovesu&b=1&f=1345321416&p=2
圖形介面的輸入方式 如同上面這個連結
Number of pairs of points: 輸入一共需要幾對資料
然後依次在time1 voltage1 time2 voltage2 ..... 輸入數值
進階用法：
在time1或voltage1之類的欄位可輸入變數名稱（variable）
例如time1='T+Trise' Voltage1='Vhigh'
然後在AnalogEnvironment裡面可以新增variable(from schematic)
然後就可以直接在Analog Environment直接指定變數的數值
同樣方法可以在transistor的Width或Length裡面輸入'Width01'、'Length01'
然後在analog environment裡面選DC、AC、或其他analysis可以sweep variable
: scale factor
: time scale factor
: transition width 代表的是什麼意思
: 請問你知道嗎?
查manual即可
: 我有試著key 一些數值進去 但還是看不出來他到表的意義 有時亂key會有error不能跑
: 不好意思 問這麼多問題
: 但我搞很久還是不行模擬電路......
[恕刪]
: 你們下線時 電路都是經過設計 分析的 手算嗎
: 要怎麼去分析?
[恕刪]
先看你要設計什麼
最大概的步驟是
1.找出Spec，找不到就猜（憑經驗）
2.找出「對的topology」（憑經驗）
3.找出該topology裡面，影響Spec的變數，還有方程式（通常是最粗淺的方程式）
（這一步非常複雜）
4.schematic模擬
5.Layout
6.Post-Layout模擬
.....差不多是這樣
憑經驗的部分可以找書、PAPER、問人
RazaviOp Amp那一章裡面有一個設計telescopic的example
看懂了之後可以稍稍體會第一步到第三步
其實仔細一點看1.到3.
跟你學習電子學的時候，算題目的步驟剛好是相反
算題目的時候，你已經知道方程式，變數了
題目給你一個topology，例如一個Diff. Amp
然後要你算Gain、Rout那些Spec
所以記住
Design是Going Backward
Ps.我是弱者，再難的我也不會了
