Tables cont ...

Wire Model - this is an important table since it adds "intelligence" to the WIRE object. By associating each 3Di WIRE with the a model and parameters that were used to generate it, one enables the 3D-VU program to display wires by "tier" or WHG and also allows an experienced user to change models or parameters or to even create new wire models as needed to properly model the wires.

A group of wires may share a common WIRE_MODEL when:

1. they share the same wire model
   
   and
   
   
2. They share the same model parameters
   
   and
   
   
3. they have the same starting and ending Z-height.
   

Available Wire Models

Each wire model must be coded into the APD-3D program and also into 3D-VU if it is to be "rebuildable." Currently the following models are available:

artwork_4p - a model for short wirebonds. (H1, L1)

artwork_5p - a model for longer wirebonds with a "worked" shape. (H1 H2 L1 L2)

jedec_4p     - JEDEC simplified model. (H1,alpha)

jedec_5p     - JEDEC advanced model. (H1, alpha, beta)

NOTE: Artwork has since developed user defined wire models. So the above information is no longer really useful.

Syntax for the Wire Model Table

TABLE WIRE_MODEL
<index> <model_name> <direction> <param> <param> <param> <param> ...

where

     index       index number for this entry; a positive integer

     model_name  name of model used to generate this wire 

     direction   FORWARD | REVERSE       
                 
                 FORWARD from x1,y1 to x2,y2 
                 REVERSE from x2,y2 to x1,y1

     parameter   model parameter 

Examples

              TABLE WIRE_MODEL
              1  artwork_4p FORWARD  100  250
              2  artwork_5p FORWARD  100  150  350  400
              3  jedec_4p   FORWARD  100   85
              4  jedec_5p   FORWARD  100   85  15
