Eldo Netlist Setup
Device Libraries
Device Libraries
To include model or subcircuit definitions from library files into the current input netlist the
following statements are available. Eldo includes the whole contents of the file specified.
• .INCLUDE
Inserts the contents of a file into a .cir file. For example:
.INCLUDE circuit_addon.inc
Specifies that the contents of the circuit_addon.inc file be included in the circuit
description file (netlist). In this case, the included file is resident in the same directory as
the netlist.
See “.INCLUDE” in the Eldo Reference Manual.
• .LIB
Inserts model or subcircuit definitions into an input netlist from a library file. For
example:
.LIB models.lib
Specifies that any model and subcircuit information missing in the input netlist should
be taken from the file models.lib. The models.lib file could contain model definitions for
example:
*BJT model definition
.model qmod npn bf=160 rb=100 cjs=2p
+ tf=0.3n tr=6n cje=3p cjc=2p vaf=100
*...
The input netlist could contain the following reference to the model defined:
*main circuit
q23 10 24 13 qmod
Specifies the bipolar transistor q23 of model type qmod.
See “.LIB” in the Eldo Reference Manual.
• .ADDLIB
Searches a directory for files with extensions .mod, .ckt, .sub and include in the .cir file
the contents of files with names corresponding to referenced model and subcircuit
definitions. For example:
mn1 a b c d mna w=w l=l
*...
.ADDLIB 2 /users/examples/
.ADDLIB 1 /users/models/
