The SPICE Export Options
dialog allows you to set options for exporting
a SPICE netlist in Electrical Editor. It is displayed by clicking
Option > 
SPICE Export Options on the main menu in
Electrical Editor.
File
| Value | Description | |
|---|---|---|
| Output File Generation | Single File | If selected, then information is exported to the SPICE netlist as a single target file (.sp). |
| Separated File | If selected, then sub-circuits and connection information in the SPICE netlist file is exported to a separate file (.inc). | |
| Copy Model Files | If selected, then an IBIS or IdEM model is copied to the output folder for the SPICE netlist. This setting is not used for HSPICE simulation. |
IBIS Package
| Value | Description | |
|---|---|---|
| Include Package as Individual Sub-circuit | If selected, then package models are exported with a buffer model (a B element). The connection between driver pin and receiver pin is included in the sub-circuits. | |
| Include Package in Interconnect Sub-circuit | If selected, then a package model is exported into the sub-circuits. The connection between driver die and receiver die is included in the sub-circuits. | |
| Ignore Package | If selected, then a package model is not exported to the SPICE netlist. | |
| RLC Package Modeling | Allows you to specify how to handle a package of IBIS models. The option that you select is also applied in the RLC Package Modeling section in the Simulator Options and TDR Analysis Options dialogs. | |
| Lumped Elements | If selected, then a package is simulated as a lumped constant model. This is usually the case when no distributed constant model is described as a package model for IBIS models. However, in cases where fast signals or electrically long tracks are involved, it may not be appropriate to use a lumped constant model. | |
| Transmission Line | If selected, then a distributed constant model is used to perform the simulation. This is created by converting the RLC values of the lumped constant model. This allows you to suppress unrealistic ringing, which makes it more likely that simulation results are similar to measured results. This setting is also applied to HSPICE data export. |
