Inductor Element

아래 문자열들은 inductor를 정의한다. (붉은 글자는 필수 항목임)

 

Lxxx n1 n2 <mname> <l <tc1 <tc2>>> <SCALE=scale> <M=m> <R=r>+ <parnam=pval> ... <$SUB=ns> <$[mname] | $.MODEL=mname>+ <$X=x> <$Y=y> <$D=d>

+ <parnam=pval> ... <$SUB=ns> <$[mname] | $.MODEL=mname>

+ <$X=x> <$Y=y> <$D=d>

 

첫번째 구문에서의 mname과 "l" parameter 순서는 바꿀 수 있다. 만약 mname 과 "l" 둘 중 하나가 숫자로 인식될 수 없다면(예를 들어 숫자가 아니거나 미리 정의된 parameter가 아닐 경우) 이는 mname parameter로 가정한다.

다른 모든 calibre 디바이스들과 마찬가지로 $[mname] 또는 $.MODEL=mname 으로 지정된 model은 줄 앞쪽에서 지정된 model보다 우선된다.

Model 이름은 정의되지 않은 parameter로 인해 해당 위치의 이름을 숫자 값으로 평가하지 못하여 'tc1' 값과 구별된다. 따라서 parameter와 model 간의 이름 충돌을 피해야 한다. 이러한 충돌을 피하지 못하면 inductor의 잘못된 인식이 발생하여 tc1에 대해 정의되지 않은 parameter 오류가 발생하고 대신 parameter가 inductor의  model name이 될 수 있다.

 

실제 예는 아래와 같다.

Calibre는 구문이 모호하면서 3-pin 또는 4-pin 디바이스로도 해석 될 수 있는 경우에는 MOSFET을 4-pin 디바이스로 해석한다.

Rule file에서 M인 element name을 가진 디바이스는 디바이스 인식을 위한 사용자 정의로 간주되지만, hierarchical layout netlist에서 primitive subcircuit을 호출하지 않고 SPICE MOS element로 표현된다. 예를 들어,

 

DEVICE m(h) gate gate(g) sd(s) sd(d) bulk(b) [

   property w, l ....

]

 

위와 같은 룰 파일은 와래와 같은 layout netlist를 생성한다.

 

M1 1 2 3 4 h w=2e-6 l=1e-6 $X=210000 $Y=200000

 

이러한 M 디바이스 표현을 사용하기 위해서는 디바이스가 다음과 같은 조건을 충족해야 한다.

- Element name은 M 또는 m이어야 함

- 디바이스는 G, D, S의 3개 혹은 옵션pin B를 포함한 4개의 pin을 가지고 있어야 함

- G와 B는 다른 어떤 pin과도 위치가 바뀔 수 없음

- 모델 이름이 반드시 표시되어야 함

 

위의 네 가지 항목을 충족시키지 못하는 경우에는 디바이스는 아래의 예와 같은 pirimitive subcircuit 호출로 표현된다.

 

.SUBCKT m g s d b

.ENDS

 

X1 1 2 3 4 m $[h]

 

또한 4개보다 많은 pin을 가진 transistor도 사용자 정의 디바이스가 되어 이와 동일하게 primitive subcircuit 호출로 표현된다.

Without $LDD:

mname 이 M 또는 m으로 시작하면 : MN

mname 이 P 또는 p으로 시작하면 : MP

mname 이 E 또는 e으로 시작하면 : ME

mname 이 D 또는 d으로 시작하면 : MD

그 외의 경우 :  M

mname 이 E 또는 e으로 시작하면 : LDDE

mname 이 D 또는 d으로 시작하면 : LDDD

그 외의 경우 :  LDD
