Now, the question is, how can we describe a simple sequential circuit in necklace in this lecture,
I will talk about a straightforward approach to define a simple sequential circuit in us.
Let's start with our sequential second model explained in the previous section, a sequential circuit
consists of a combination of circuit and a set of memory cells to save the circuit states.
The circuit performs its task throughout several cycles.
The clock cycle period is defined by the longest part in the combination of circuit.
Which has the highest propagation delay.
In each club cycle, the combination circuit reads, the current state from the memory cells, generates
the outputs and the next state and finally save the next state in the memory cells.
This sequence diagram gives us an idea.
We should describe the combination of circuit to be synthesized and Escadrille in one single cycle.
The key function describing our design should have four main parts.
We should define some memory cells or registers for this purpose, we can use C++ as static variables.
These registers save the circuit states.
Read from Reducers, perform the desired logical arithmetic tasks, and finally modify the registers.
That's the whole design code should be scheduled in one cycle, let's call this approach as single cycle
design.
Through a couple of examples, we will realize that this approach can provide a high performance design
comparable to the ideal design techniques.
Now, how can we use this single cycle design technique to design a real circuit in the next lecture,
we will start to design a parallel to Sariel Convertor logic circuit based on this idea.
Our takeaway messages are static variables in C C++ can be used to define registers in a sequential
circuit to give the states the single cycle sequential circuit description in Etchells consists of four
parts.
Define a set of registers, read the states from registers, perform the logic or arithmetic operations,
and finally write the results back to the registers.
Now, the police question, this coat shows an excellent description for a second short circuit.
And this diagram depicts this casual view of the second after syntheses, the code is correct and has
its own application, but what is the potential issue with this code based on the single cycle design
idea?
Can you change the code to follow the coding style introduced in this lecture?
