B2 Spice A/D v4 Special Features

In addition to a vast library of standard parts, B2 Spice A/D v4 contains some special parts and abilities that set it apart.

Multiple bit ports and buses in both Mixed Mode and Pure Digital mode:

The ability to share models or make each model unique:

Shared model mean that they share a common behavior and that changing the parameters of one will change it for all shared models.  In the example below, the 2 transistors are being shared.  Changing the "ideal forward beta" of one of the transistors results in both transistor's betas being changed. 

Parameterized Subcircuits:

Parameterized subcircuit parts are user-definable parts that can use custom parameters inside the subcircuit text.  An example of this is the Battery in our parts library.  To create a parameterized subcircuit part, all you need to do is

Then just pull up your part in workshop and double click to access your custom part!

Password protected Device Defects:

This feature will be appreciated by educators.  B2 Spice A/D v4 allows you to set defects on any part on a circuit and then password protect it.  Users will still be able to modify the circuit, run simulations and create netlists but will not be able to access the defects until the password is entered.

Create part from circuit

B2 Spice A/D v4 allows you to take any circuit and create a part from it with just a few clicks.  Then you have the ability to pull the part from the database and use it like you would any other part.

So just take this circuit:

and create a part out of it by:
