Eldo Netlist Setup
Parameter Names
The inline comment character (! or *) must be preceded by a white space. If not, Eldo could
ignore it in the case of a parameter value, or consider it a valid character in node names. In the
example below, the first line is accepted, without any error or warning message, to be identical
to the second:
r1 1 2 5! 22
r2 2 0 5 22
“5!” is interpreted as the number 5 and the 22 is parsed as the TC1 temperature coefficient.
A set of comment lines can also be grouped together into a block as shown below:
#com
A block of
comment
#endcom
In these cases the * character is not needed.
Tip
See “.COMCHAR” in the Eldo Reference Manual.

Parameter Names
Parameter names may contain an arbitrary sequence of alphanumeric characters, including %, $,
#, _, !. Parameter names cannot be broken at the end of a line. Parameter names should not
contain boolean operators. Such a name can be quite ambiguous.
String Parameters
Eldo accepts quoted character strings as parameter values. These string values may be used for
model names and filenames. To use a string as a parameter, enclose the string within double
quotes, for example:
.param TT1="ResMod"
A string parameter can be defined on multiple lines if the string on each line is enclosed within
double quotes, for example:
104
