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 More examples can be downloaded from here: You can easily simulate, analyse and modify operation and timing ofthe examples. The program comes with built in demo circuits. Only the first compile time error is displayed. The gates.sdemo 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. It is possible to describe acircuit in a box using a very small subset of Verilog. The virtual digital oscilloscope has the following currentfeatures: start, stop time, buffer length setting, time shift andzoom, up/down scroll, display of logical low, high, and undefinedstates. Flip flopsmay enter a metastable state in these cases. Flip flop setup, hold, recovery, resume time violations. When an input receives an impulse shorter than theconfigured value. When connected outputs havedifferent or undefined levels and have low or undefinedimpedance. Detected errors are: Temporary short circuit conditions. The simulator detects run time errors and puts error messages onthe schematic. Switch level modelling, gate level modelling and complex devicelevel modelling can be mixed in a circuit. Wires optionally can display logic levels. The digital circuit simulator works with three logic levels andthree impedance values. Scheme editor features: custom subcircuit (black box), contextsensitive menu, autorouter, 7 steps undo/redo, labels for farconnections, automatic enlarge on selection, cloning, rotating,locked and unlocked move, vertical and horizontal alignment, moveto center. E.g.B.C.~LT.~BI/RBO.~RBI.D.A.GND.e.d.c.b.a.g.f.Vcc The place of the custom circuits is the 'ics' directory.

The number of port labels must be equal tothe number of ports. If the port is negatedthan start label with ~. Sub circuits on breadboardmay have port labels.

The scheme editor comes from & logics app with someimprovements. 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. Wire to resistor,LED,LED+resistor transformation. Power connectors, two independent clock generators, scope with 32channels. The breadboard has the following features.
