B2 Logic v3de Beige Bag Software
Diseñar circuitos digitales es muy fácil con B2 Logic. Seleccione cientos de componentes de entre una amplia variedad de familias para crear sus circuitos. Ejecute la simulación interactiva y pruébela colocando sondas. A medida que la simulación progresa, los valores de señal cambian en las sondas, así como en un diagrama de tiempos asociado a una hoja de cálculo.
Features
- Fully integrated and interactive
B2 Logic allows you to build the circuit on the screen and test it by
placing probes in the circuit. As the simulation progresses, the signal
values change in the probes in the circuit, as well as in a timing diagram
and in a spreadsheet. You can change the input values by clicking directly
in the inputs in the circuit.
- Multiple components
There are over 100 primitives of components available.
- Multiple libraries
B2 Logic comes with five built-in libraries. You can also create your own
libraries.
- Customize device properties
You can modify propagation delays and other characteristics of devices in
your circuit, and of the models of devices in the libraries.
- Flexible analysis
With a click of the mouse, you can specify initial conditions and delay
times of the circuit.
- Simulation diagnostics
B2 Logic reports timing violations on dynamic components (e.g. flip-flops)
to the user while the circuit is running.
- Accurate simulation
B2 Logic simulates the propagation delays and set-up and hold times for each
device according to the specifications in the Logic Data Books.
- Multiple signal values
The value of a signal consists of both signal level and strength. There are
three levels and four strengths.
- Subcircuits
You can build a circuit, save it, and then open it as a component in another
circuit. You can probe the inside of a subcircuit.
- Buses
B2 Logic allows you to group a set of wires together into a single bus,
which keeps large circuits compact and easy to edit and debug.
- Generic PLD simulation
Simulate PLD's from truth tables, equations, or Espresso format tables. B2
Logic supports internal flip-flops. You can simulate ROM from data tables.
- Program Limitations
B2 Logic is not a printed circuit board design package. It is useful for
verifying design ideas and for analyzing the timing of circuits. B2 Logic
circuits are not currently portable to other programs. B2 Logic does not
allow import of third party parts libraries.
