Simulator Compatibility
Spectre Compatibility Description
You can manually remove these folders if they are no longer required. Specify an alternative
output directory with the -spectre_out pathname argument.
The spice_command_file must not include the spectre_file. Eldo automatically performs the
link between these files. Attempting to include the Spectre file will not function, and the
simulation will stop. For examples, see Include Files in “Troubleshooting the Spectre to Eldo
Flow” on page 186.
All SPICE commands (.PLOT/.PROBE/.STEP/.EXTRACT, and so on) can be used except for
the .ALTER command, where the mapping is not handled. When specifying a name for the
.PLOT command, the Spectre names can be used.
Here follows a simple example:
spectre_file.sp:
simulator lang=spectre
subckt foo a b
Aresfoo a b resistor r=1k
ends
subckt bar a b
Aresbar a b resistor r=1k
myInstance a b foo
ends
anotherInstance 1 0 bar
spice_command_file.cir:
*first line
c1 1 0 1p
I1 1 0 1
.plot tran I(anotherInstance.*)
.plot tran v(c1)
.tran 1n 10n
.end
