Spectre Compatibility
Eldo can use a Spectre netlist as input.
There are two flows to simulate a Spectre netlist in Eldo:
• Spectre Compatibility Flow
Run Eldo on the Spectre netlist. Eldo will call the spect2el script to convert netlists from
Spectre format (Spectre language syntax) into Eldo format (Eldo syntax). Additionally,
spect2el generates several files that will be used to map the Spectre name to a SPICE
name, and to avoid the reconversion of the Spectre files if nothing has changed in them.
This flow is more straightforward and more efficient. This is the preferred approach.
• Spectre to Eldo Converter Flow
This flow is based on the spect2el script that converts libraries and netlists from Spectre
format (Spectre language syntax) into Eldo format (Eldo syntax). You then run Eldo on
the converted netlist. This flow offers more flexibility, in particular if manual
modifications are necessary to workaround unexpected conversion issues. See Spectre
to Eldo Converter for more information on the spect2el script.
