*ng_script
|
|
* A somewhat complex example:
|
|
* This script loads two circuits, then selects circuit 1,
|
|
* does three dc simulations, selects circuit 2, does
|
|
* two dc simulations on the bipolar table device.
|
|
* Always do a 'reset' in between to avoid memory leaks.
|
|
|
|
* you have to create the bipolar device table first by running
|
|
* the table generator table-generator-q-2d.sp
