Interpreting the Output Log (.chi) File
After a simulation is complete, Eldo writes simulator information to an output log (.chi) file
containing ASCII data. This file contains details of the simulation including any warning or
error messages, which may have been encountered during simulation.
Depending on the analysis defined, the structure will be different, for example with .ALTER
and .STEP commands there is usually a separate section for each analysis performed with
header information and so on. Each section corresponds to an analysis defined in netlist. See
“Setting Up An Analysis” on page 203 for example outputs for different types of analysis.
Tip
You can view .chi files with the AMS Results Browser.
Output Log (.chi) File Contents
A typical ASCII output log (.chi) file contains various information related to the netlist and the
simulation.
• System Information.
Information about the machine used for simulation including: clock frequency, the
number of cores, the number of threads used, and so on.
• Date, Eldo version number, simulation time.
• Circuit name (title).
• Input Listing.
Netlist with line numbers.
• Information about netlist analysis (errors and warnings).
• Generation.
Information about the database generation.
• Information about compilation.
o
Number of elements, nodes, input signals, and so on, for example:
