Post-Layout Simulation
Eldo Post-Layout Options
and another one included by the .DSPF_INCLUDE command, corresponding to
the version with its parasitics.
Eldo will emulate a .BIND command on the instances/subcircuits which are
specified on the .DSPF_INCLUDE command.
Eldo will apply filters, if any, to the DSPF devices.
MIXED specifies the DSPF file contains either only the parasitics or both the
parasitics and the intentional devices. It is the intended subcircuit which is
considered as being reference. This third mode is a mixture of the two other modes
available. Default mode for Eldo Classic and Eldo Premier.
MIXED is similar to mode SCH in that it is the intended SUBCKT which is taken as
the reference for building the simulation database, and is similar to mode DSPF
because the DSPF file may contains both parasitics and intended devices.
See the “.DSPF_INCLUDE” command in the Eldo Reference Manual.
• .MAP_DSPF_NODE_NAME
Maps node references to a new DSPF node name.
See the “.MAP_DSPF_NODE_NAME” command in the Eldo Reference Manual.
• .IGNORE_DSPF_ON_NODE
Ignores parasitic elements on a specified node when a DSPF file has been included.
See the “.IGNORE_DSPF_ON_NODE” command in the Eldo Reference Manual.
• .SELECT_DSPF_ON_NODE
Selects parasitic elements on a specified node when a DSPF file has been included.
See the “.SELECT_DSPF_ON_NODE” command in the Eldo Reference Manual.
Eldo Post-Layout Options
The following post-layout backannotation simulation options are available in Eldo:
• COLLAPSE_DSPF_OUTPUT
Regroup currents (I, Ix, Isub) and noise outputs according to the device or subckt
instance specified in arguments.
See “.OPTION COLLAPSE_DSPF_OUTPUT” in the Eldo Reference Manual.
• DSPF_LEVEL=C|CC|RC|RCC
Defines the level of parasitics to use from a specified DSPF file. The option will use part
of the information stored in the RC extracted DSPF file specified by C, CC, RC or RCC.
