Simulator Compatibility
Spectre Compatibility Flow
Spectre Compatibility Flow
Run an Eldo simulation on a Spectre netlist with the eldo -sp command line argument.
Syntax
eldo -sp spectre_file [-i spice_command_file] [-clean_sp]
[-spectre_out pathname] [-sp_plot 2|1|0] [-css 1|0]
Arguments
• -sp spectre_file
The filename of the Spectre format netlist to be used as input for Eldo. spectre_file must be
specified with an extension. No guess is made on the possible extension. If the filename is
specified without its extension an error is generated. Required.
• -i spice_command_file
The filename of the Eldo/SPICE command file to be used in association with the Spectre
netlist. Optional. Used with the -sp argument when a Spectre netlist is the input.
spice_command_file must be specified with an extension. No guess is made on the possible
extension. If the filename is specified without its extension an error is generated. The
spice_command_file must not include the spectre_file. Eldo automatically performs the link
between these files. Including the Spectre file will not work and the simulation will stop.
• -clean_sp
Removes all the files generated by spect2el. As a consequence, if you want to relaunch the
simulation on that design, the converter will reproduce the work. This increases the overall
simulation time. Optional. Used with the -sp argument when a Spectre netlist is the input.
• -spectre_out pathname
Define the path in which the files generated by spect2el reside. Optional. Used with the -sp
argument when a Spectre netlist is the input. Eldo creates pathname automatically if it does
not exist. If –clean_sp is also specified, Eldo clears the files/subdirectories under pathname,
while pathname itself is not removed after simulation. By default, pathname is identical to
the one specified by –outpath.
• -sp_plot 2|1|0
Controls the conversion of Spectre save statements into Eldo .PRINT, .PLOT and .PROBE
commands as below:
0
The save statement is converted into .PRINT (default).
1
The save statement is converted into .PLOT.
2
The save statement is converted into .PROBE.
