Spectre to Eldo Converter
Spectre to Eldo Converter
The Spectre to Eldo converter is a tool script that converts from Spectre format (Spectre
language syntax) into Eldo format (Eldo syntax). The script is named spect2el.
For libraries including mixed-language syntax (Spectre and SPICE), Spectre to Eldo assumes
SPICE input mode when it opens an include file. All included files, except top-level files and
those with a .scs extension, that use the Spectre native language must begin with the statement:
simulator lang=spectre. Exceptions are top-level files and files that end with a .scs extension
which are read in Spectre input mode.

Installing a Patch
When an urgent fix is required, Mentor Graphics may provide a specific Spectre to Eldo
converter patch mechanism to enable the fixed version of the converter to be used with an
existing AMS installation. The patch is provided through a tar file.
Follow the instructions below to patch an older AMS tree version with a newer Spectre to Eldo
converter.
Procedure
1. Untar the patch tar file into an empty directory.
2. Run the script patchs2e that has been extracted to the directory.
3. Enter the full path of the output directory as requested by the script (must be existing
prior to running the script, the script will not create a missing directory).
