Components

This gives you information about the components in the stdcomp library.

1. Not gate (Inverter)

This produces the inverted state of the input.

Gate	Inputs	Outputs
Not	a	o

2. Controlled Inverter

This act as an Inverter when the control pin is high else low.

Gate	Inputs	Outputs
CtrlInverter	a, c(control)	o

3. Buffer

This component reproduces the input at the output.

Gate	Inputs	Outputs
Buffer	a	o

4. Controlled Buffer

This acts as a Buffer when the control pin is high else low.

Gate	Inputs	Outputs
CtrlBuffer	a, c(control)	o

5. And

This produces high only when every input is high.

Gate	Inputs	Outputs
And2	a,b	o
And3	a,b,c	o
And4	a,b,c,d	o

6. Or

This produces high signal when at least one of the input is high.

Gate	Inputs	Outputs
Or2	a,b	o
Or3	a,b,c	o
Or4	a,b,c,d	o

7. Nand

It produces output which is complement to that of an AND gate.

Gate	Inputs	Outputs
Nand2	a,b	o
Nand3	a,b,c	o
Nand4	a,b,c,d	o

8. Nor

It produces output which is complement to that of an OR gate.

Gate	Inputs	Outputs
Nor2	a,b	o
Nor3	a,b,c	o
Nor4	a,b,c,d	o

9. Xor

The output of an XOR gate is high only when odd number of inputs are high

Gate	Inputs	Outputs
Xor2	a,b	o
Xor3	a,b,c	o
Xor4	a,b,c,d	o

10. Xnor

The output of an XNOR gate is high only when even number of inputs are high

Gate	Inputs	Outputs
Xnor2	a,b	o
Xnor3	a,b,c	o
Xnor4	a,b,c,d	o

11. Positive Trigger

The output of this module is high when input changes from low to high

Gate	Inputs	Outputs
PosTrig	i	o

11. Negative Trigger

The output of this module is high when input changes from high to low.

Gate	Inputs	Outputs
NegTrig	i	o
