Diode Instance, Geometric (Level 3)

 

Geometric Diode Netlist Syntax

The Level 3 geometric diode instance has two formats:

Dxxxx n1 n2 modelname [[AREA=]val [PJ=val]

[WP=val] [LP=val] [WM=val] [LM=val]

[M=val] [DTEMP=val]

or

Dxxxx n1 n2 modelname [W=val] [L=val]

[WP=val] [LP=val][WM=val] [LM=val]

[M=val] [DTEMP=val]

n1 is the anode and n2 is the cathode of the diode. modelname is the name of a geometric (Level 3) diode model defined in a .MODEL statement elsewhere in the netlist. In the first format, the label AREA= is optional, but is recommended for clarity.
