What is BinPy?
---------------
BinPy is a digital electronics simulation library with a bunch of digital devices ( and a few experimental analog devices ) and tools / algorithms under its hood. BinPy is aimed towards students, helping them learn about digital logic in an interactive way. Being an open source project makes it easier for one to get an indepth understanding of the the underlying concepts by glossing at the source.
BinPy focusses on the fundamentals. Everything has been written from scratch such as gates, logical operations, etc.
Our future goals include a GUI tool to help easily build simple digital circuts and the implementation of the core using SPICE or equivalent tools for precise simulations.
How to use
----------
Here's an example of SR latch constructed from a pair of cross-coupled NOR gates
[ Image of SR Latch taken from Wikipedia ]
[ BinPy Code to Simulate an SR Latch ]
```python
from __future__ import print_function
from BinPy import *
# Connector to connect output of second NOR gate with input of first NOR gate
con1 = Connector()
# Connector to connect output of first NOR gate with input of second NOR gate
con2 = Connector()
R = 0 # Reset input for the SR-Latch
S = 0 # Set input for the SR-Lacth
NOR1 = NOR(con1, R) # First NOR gate
NOR1.setOutput(con2) # Set output for NOR gate
NOR2 = NOR(con2, S) # Second NOR gate
NOR2.setOutput(con1) # Set output for NOR gate
NOR1.setInput(1, 1)
NOR2.setInput(1, 0) # Set state
print('Q: ', NOR2.output(), '\t', 'Q\': ', NOR1.output())
NOR1.setInput(1, 0)
NOR2.setInput(1, 1) # Reset state
print('Q: ', NOR2.output(), '\t', 'Q\': ', NOR1.output())
NOR1.setInput(1, 0)
NOR2.setInput(1, 0) # Hold state
print('Q: ', NOR2.output(), '\t', 'Q\': ', NOR1.output())
NOR1.setInput(1, 1)
NOR2.setInput(1, 1) # Invalid state
print('Q: ', NOR2.output(), '\t', 'Q\': ', NOR1.output())
```
<strong>Output</strong>
```python
Q: 1 Q': 0
Q: 0 Q': 1
Q: 0 Q': 1
Q: 0 Q': 0 #Invalid State
```
<strong>Operations, Combinatonal Logic and Algorithms</strong>
```python
from BinPy import *
# Operations
operator = Operations()
operator.ADD(1011,11)
operator.SUB(1011,11)
operator.COMP('0011',1) #Second argument chooses betweem 1's or 2's Compliment
# Combinational Logic
m = MUX(1,1,0,1)
m.selectLines(0,1)
print "MUX Out: ", m.output()
d = DEMUX()
d.selectLines(0,1)
print "DEMUX Out: ", d.output()
d = Decoder(0,1)
print "Decoder Out: ", d.output()
e = Encoder(0,1,0,0)
print "Encoder Out: ", e.output()
# Sequential Circuits
a = DFlipFlop(1,0)
print "DFlipFlop Out: ", a.output()
# IC
myIC = IC_7400()
p = {1:1,2:0,4:0,5:0,7:0,10:1,9:1,13:0,12:0,14:1}
myIC.setIC(p)
print "IC_7400 Out: ", myIC.run()
myIC1 = IC_7401()
p = {2:0,3:1,5:0,6:0,7:0,8:1,9:1,11:0,12:0,14:1}
myIC1.setIC(p)
print "IC_7401 Out: ", myIC1.run()
# Algorithms
# Includes the Quine-McCluskey algorithm for solving K-Maps
FinalEquation = QM(['A','B'])
print "Minimized Boolean Equation : " , FinalEquation.get_function(qm.solve([0,1,2],[])[1])
```
<strong>Output</strong><br/>
```python
{'carry': 0, 'sum': [1, 1, 1, 0]}
{'carry': 1, 'difference': [1, 0, 0, 0]}
MUX Out: 1
DEMUX Out: [0, 0, 0, 0]
Decoder Out: [0, 1, 0, 0]
Encoder Out: [0, 1]
DFlipFlop Out: [1,0]
IC_7400 Out: {8: 0, 11: 1, 3: 1, 6: 1}
IC_7401 Out: {1: 1, 10: 0, 4: 1, 13: 1}
Minimized Boolean Equation : ((NOT B) OR (NOT A))
```
BinPy also comes with a console that is a simple wrapper around the classic python console from which you can directly use the BinPy Resources.
To start it, simply issue ```$ binpy``` if BinPy is installed in your path.
