KB: シミュレーション結果の予期しない動作を防ぐために、Spiceモデルのピンを回路図シンボルにマッピングする

Solution Details

A general procedure of finding and linking Spice model to component can be found at:
Adding Simulation Models to the Design

The pin mapping can be checked with the symbol selected in schdoc, in Properties panel, on General tab, under Parameters section, double-click on Simulation object to open a dialog where you can check/modify under Pin Mapping section.

For all .SUBCKT statement, it is of standard notation in Spice to list pin name in ascending order of pin index starting with 1.
Linking a Simulation Model

For .MODEL statement, it is implicitly defined in Berkeley Spice 3f5 as below:
http://bwrcs.eecs.berkeley.edu/Classes/IcBook/SPICE/UserGuide/elements_fr.html
So for example, in BJT, the pin order in model is C (1), B (2), E (3) to which schematic symbol has to be mapped manually, if different.


As a side note, pin mapping of managed component in A365 has to be done in batch editing mode:
Pin Mapping

In a file-based DBLib, the simulation model related attributes can be specified as described below:
Simulation Model Mapping
Make sure that the database is clean for each attribute, with no trailing space characters for example, as it is known to prevent the model from being linked properly.

For multi-part component, by default, each part of the symbol is considered to be a separate component with the assigned Spice model by the simulation engine. In order to exclude part from simulation, the checkbox "Exclude part from simulation" in Sim Model dialog has to be ticked.

For homogeneous multi-part component (multiple copies of the same circuit model), the same mapping can be applied to all parts.
For heterogeneous component, on the other hand, all varying models needs to be encapsulated into a single file with a .SUBCKT wrapper statement.
e.g.
.SUBCKT MMDT3946 1 2 3 4 5 6
Q1 3 5 4 DI_MMDT3946_PNP
Q2 6 2 1 DI_MMDT3946_NPN
