Working with Multiple Languages
The Spectre to Eldo converter supports multiple languages (Eldo, Spectre, SPICE) inside the
same netlist. To switch between the different language modes, use one of the following methods
provided:
• To encapsulate portions of different languages specify start and end lines with the
syntax:
Simulator lang=ELDO|SPECTRE|SPICE
...
...
End lang=ELDO|SPECTRE|SPICE
• To encapsulate the language of included files (within the encapsulated lines) to be the
same as the parent file specify start and end lines. This avoids any need to specify
Simulator lang at the beginning of the called files.
Included lang=ELDO|SPECTRE|SPICE
...
...
End lang=ELDO|SPECTRE|SPICE
Specify End lang to return the simulation language to the default one.
Note
To keep compatibility with Spectre behavior, the language of the included file can
be determined using the “Priority Rules” on page 186, in other words, the included
file does not have to be in the same language as its parent file.
• To change the default language, invoke the Spectre to Eldo converter with the -lang
keyword argument.
spect2el -lang eldo|spectre|spice
By default the Spectre to Eldo converter assumes Spectre syntax for the main file
specified by the -file_list argument in the specte2el command line. Otherwise, all
included files are assumed to be in Spice syntax by default to match Spectre behavior.
