           Part Type Library Help 

Part Type items are used to specify the
electrical & packaging information
associated with a part.

-------------------------------------------
The format for a Part Type items is:
-------------------------------------------   
(Items that are not in capital letters are
Optional)

alpha flags cpins

APINNO APINNO ...
------------------------------------------
>NAME DNM:dnm type lines gates sigpins 
alpha flags

NAME : Part type name (up to 16 chars)
DNM :  PCB DECAL name(s) (up to 16 chars)
       alternate decal names are separated 
       by ":" (Max. 4 alternates)
type : Logic type of the part type. Any
       three char name, i.e.:
       UND   Undefined logic type
       TTL   TTL logic type
       CMO   CMOS logic type
       ECL   ECL logic type
       ANA   Analog logic type
lines: Number of user defined text lines.
       Line beginning with @ is used by TTL 
       parts ie. \00 \01 ; to specify
       aliases ?4LS 54ALS etc.
gates: Number of gates in the part type
       up to 20 gates in a part type
sigpins: Number of pins assc. with 
       special signal names.
       Up to 50 signal pins in a part.
alpha: Number of alphanumeric pin numbers
       specified in part type (if feature
       is used there must be a unique 
       "number" for every pin in the part.
flags: 0 = normal part
       1 = connector part
       2 = special part for off-sheet refs.
       If 128 added - part has an error.
cpins: Number of pins for a connector part.
------------------------------------------
>G:gdnm:gdnm SWPTYP PINS

gdnm:   Gate decal name(s) (up to 16 chars)
        alternate decal names are separated 
        by ":" (Max. 4 alternates).
SWPTYP: Gates with the same swaptype
        are assumed to be electically 
        equivalent.
        (SWPTYP = 0 means not swapable).
PINS:   Number of pins in the gate
------------------------------------------
>PINNO.swptyp.pinTyp.pinName

PINNO:  Electrical pin number of pin in gate
swptyp: Pins with the same swap type 
        are assumed to be electrically 
        equivalent.
        (swptyp = 0 means not swapable)
pinTyp: Pin electrical type
        S  source pin
        B  bidirectional pin
        C  open collector pin
        O  ortieable source pin
        T  tristate pin
        L  load pin
        Z  terminator pin
        P  pwr pin
        G  ground pin
        U  undefined
pinName: Electrical pin name of pin in gate.
------------------------------------------
>[SIGPIN] PINNO WIDTH SIGNM

PINNO : Part pin number to assc. the signal
        name with.
WIDTH : Track width to assc. with the connec-
        tion to this pin.
SIGNM : Signal name assc. with the pin.
        (up to 12 chars. in name)
------------------------------------------
>APINNO APINNO ...

APINNO: Alphanumeric pin number up to 4 
        characters long. 
        1st "number" in list corresponds to 
        electrical pin #1 and so on. 
        There must be same number of alpha 
        numbers as there are pins on the
        part.
