Spectre to Eldo Converter
• For proper conversion of netlists or libraries, all the included files should exist. If any
instance in the input library or netlist refers to a model, a subcircuit, or a Verilog-A
module, which is not defined in the input library/netlist or one of its included files, this
instance cannot be recognized or converted and a warning message is displayed in the
running terminal. The conversion continues if running the tool in standalone mode.
However, if running the tool from inside Eldo, the converter exits with error code 10
informing that this line is not converted and the conversion process will not continue
until this error is corrected. A file named spect2el.error is generated clearly describing
the errors.
• If model parameters wdexp and ldexp are not specified in the Spectre resistor model,
then the converter prints them with a default value equal to 1. If model parameter AF is
not specified in the Spectre resistor model, then the converter prints it with a default
value equal to 2. In the case of a resistor instance, the converter ignores the printing of
{wdexp, ldexp, weexp, leexp}.
Netlist Conversion
The netlist conversion features come with the spect2el tool. This feature automates the netlists
conversion process from Spectre syntax to Eldo syntax. The following features are supported:
Analyses
• AC analysis
• DC analysis
• Transient analysis
• S parameters analysis
• Monte Carlo analysis
• Sweep analysis
• Noise analysis
• Sensitivity analysis
• Transfer function analysis
• Stability analysis
Note
The above analyses types are partially supported. There are some combinations that
are not yet supported.
