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. They are listed on the next page.
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.
