SIS is an interactive tool for synthesis and optimization of sequential circuits. Given a state transition table, asignal transition graph, or a logic level description of a sequential circuit, it produces an optimized net list in the

This article focuses on using Verilog to describe synchronous sequential circuits. In a previous article, we discussed the description of combinational circuits using Verilog language elements. This article focuses on describing synchronous sequential circuits. We’ll first look at a general model ...

Properties of dataflow programming languages. Traditionally, a program is modelled as a series of operations happening in a specific order; this may be referred to as sequential: p.3, procedural, control flow (indicating that the program chooses a specific path), or imperative programming.The program focuses on commands, in line with the von Neumann: p.3 vision of sequential programming, where ...

A combinational circuit can be defined as a circuit whose output is dependent only on the inputs at the same instant of time where as a sequential circuit can be defined as a circuit whose output depends not only on the present inputs but also on the past history of inputs. Further differences between combinational and sequential circuits can be listed as follows:

This is a basic synchronous edge detection circuit. The input, sig_a, is sampled on each rising edge of the clock, clk.The sampled value is registered; that is, sig_a_d1 is the value of sig_a delayed by one clock cycle. The output will go to a 1 when there is a rising edge on the input. The assignment to sig_a_risedge is responsible for this. It says that "there was a rising edge on sig_a if ...

In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively.Instead of elementary algebra where the values of the variables are numbers, and the prime operations are addition and multiplication, the main operations of Boolean algebra are the conjunction and denoted ...

The conventional Verilog wisdom has it all wrong. There is no problem with using blocking assignments for a local variable. However, you should never use blocking assignments for synchronous communication, as this is nondeterministic.

This article provides guidance on troubleshooting common I2C issues. Issue #1: No START Condition Generated. The PIC ® microcontroller operating as an I2C master generates a start condition to begin an I2C data transfer. If no start condition is generated then there is something wrong with the setup.
