Netlist in Compat Mode
Some aspects of the netlist syntax are different in HSPICE compatibility mode.
Comment Character
Dollar $ is used as the comment character in the netlist line instead of !.
Simulator Compatibility
Netlist in Compat Mode
The comment character is usually treated as such only if the preceding character is a blank space
or if the comment is at the beginning of a line. In -compat mode with the comment character $,
then the above rule still applies; additionally, the $ character is a comment character if:
• the preceding character is not a white space, and
• the first character of the string is ‘, ’, “, a number, or a period (.)
If you want to reference an environment variable using the $ character, for example to specify a
file path, surround the path and filename in quotes.
Examples:
• Circumstances where $ is treated as a comment:
o $ is treated a comment because the string begins with the digit 0:
M1... l=0.1u$
o
$ is treated a comment because the preceding character is a blank space:
M1... l=0.1u $
.INCLUDE $HERE/myfile.txt
o
$ is treated a comment because the first character is a number:
M1 1$ d g s b nmos w=1u l=3
• Circumstances where $ is not treated as a comment:
Wildcard Support
M1 a1$ d g s b...
M2 ‘1$’ d g s b ...
.INCLUDE "$HERE/myfile.txt"
The “?” wildcard character matches a single character in compat mode; it is not supported in
default Eldo unless a “*” wildcard character is also specified.
