Publisher Description




& logics is a logic circuit simulator with an integrated scheme editor and a waveform browser.


Currently available schematic components:


Transistors: NMOS, PMOS


Logic gates: buffer, inverter, and, nand, or, nor, exor, exnor, tri-state buffer and inverter


Flip flops: D latch, edge triggered D, JK flip flops, monostable


Multiplexers: 2 to 1, 4 to 1, 8 to 1.


Demultiplexers: 1 to 2, 1 to 4, 1 to 8


Indicators: LED, oscilloscope probe


Displays: decimal, hexadecimal


Switches: toggle button, push button


Constants: high and low.
Scheme editor features: custom subcircuit (black box), context sensitive menu, autorouter, 7 steps undo/redo, labels for far connections, automatic enlarge on selection, cloning, rotating, locked and unlocked move, vertical and horizontal alignment, move to center.
The digital circuit simulator works with three logic levels and three impedance values. They are low, undefined and high.
Wires optionally can display logic levels.
Switch level modelling, gate level modelling and complex device level modelling can be mixed in a circuit.
The simulator detects run time errors and puts error messages on the schematic.
Detected errors are:
Temporary short circuit conditions. When connected outputs have different or undefined levels and have low or undefined impedance.
Spike detection. When an input receives an impulse shorter than the configured value.
Flip flop setup, hold, recovery, resume time violations. Flip flops may enter a metastable state in these cases.
The waveform browser is a virtual digital oscilloscope. The current features are: start, stop time, buffer length setting, time shift and zoom, display of logical low, high, and undefined states.
The 3.x releases contain HDL extension. It is possible to describe a circuit in a box using a very small subset of Verilog. The gates.s demo loads the following module from simple.v file:
module smpl_circuit (A,B,AND,NAND,OR,NOR,XOR,XNOR,BUF,NOT);
input A,B;
output AND,NAND,OR,NOR,XOR,XNOR,BUF,NOT;
and #10 g0(AND,A,B);
nand #10 g1(NAND,A,B);
or #10 g2(OR,A,B);
nor #10 g3(NOR,A,B);
xor #10 g4(XOR,A,B);
xnor #10 g5(XNOR,A,B);
buf #10 g6(BUF,A);
not #10 (NOT,A);
endmodule
and the test1.v file:
module circuit(A,B,C,y);
input A,B;
output y;
wire e;
and #30 g1(e,A,B);
or #30 g2(y,e,C);
endmodule
There is no runtime error detection inside the boxes.
Only the first compile time error is displayed.
The program comes with built in demo circuits. They help you to get started quickly.
See http://www.hexastyle.com/home/andlogics/first-3-steps for details.
You can easily simulate, analyse and modify operation and timing of the examples.
Built in examples:
74160, 74163 synchronous counter
74180 parity generator checker
74181 4 bit ALU
74147, 74148 priority encoder
transistor level modelling of CMOS gates
