COMMAND LINE ARGUMENTS IN C

COMMAND LINE ARGUMENTS

  • Here the argument are passed to main functions through the command prompt and its very useful feature in c language 
  • the CLM consists of two main argument passing variables that are  INT  ARGC and CHAR **ARGV[]  , 
  • The argc shows the number of argument that has been passed to the main function through command prompt. and it will be in the integer data type .
  • The character array argv[] has been used to store the arguments . and here the argv[0] will consists of program name and agrv[1],argv[2]...will consists of argument values.  

        the main syntax of command line argument is given below

                          #include <headerfile.h>

                          void  main(int argc ,char ** argv[])
                              {
                             
                             }



   =>   let us see an example for command line argument .
        Addition of two numbers

           1.In TC   c:/tc/bin
            program name : add.c

          
              #include<stdio.h>
              #include<conio.h>
              void main(int argc,char  **argv[])
              {
                      int a,b,c;
                     a=atoi(argv[1]);

                     b=atoi(argv[2]);   //atoi can be used to covert character to integer
                  
                      if(argc!=3)
                       {
                          printf("invalid input");
                          exit(0);
                        }
                     
                      c=a+b;
                    printf("c= %d",c);
              }

AVR - SPI - Serial Pheripheral Interface Tutorial - ATmega8 Code

AVR - SPI - Serial Pheripheral Interface Tutorial - C Code Example - ATmega8 Code


AVR ATMega8 microcontroller has inbuilt SPI module. First SPI intorduction, and then let us see how to use it.

Serial Peripheral Interface Bus or SPI  bus is a synchronous serial data link standard, named by Motorola, that operates in full duplex mode. Devices communicate in master/slave mode where the master device initiates the data frame. Multiple slave devices are allowed with individual slave select (chip select) lines. Sometimes SPI is called a four-wire serial bus, contrasting with three-, two-, and one-wire serial buses. SPI is often referred to as SSI

TANNER EDA SELF LEARNING TUTORIAL- PART I

Why Tanner?
  • Low total cost of ownership :It is a software platform that is cost-effective and easy to use
  • Technological innovation: It's design tools are significantly less expensive.
  • Flexible PC-based solutions.

Tanner EDA is a suite of tools for the design of integrated circuits. Tanner EDA is mainly used to analyze circuits at switch level & gate level. These are tool used to
  •  enter schematics
  •  perform SPICE simulations
  •  do physical design (i.e., chip layout)
  •  perform design rule checks (DRC) and layout versus schematic (LVS) checks.

Tanner EDA Design Tools:
  • S-edit       - a schematic capture tool
  • T-SPICE    - the SPICE simulation engine integrated with S-edit
  • L-edit       - physical design tool
  • W-edit     - waveform formatting
 
Improve simulation accuracy with advanced modeling features
                T-Spice provides extensive support of behavioral models using Verilog-A, expression controlled sources, and table-mode simulation. Behavioral models give you the flexibility to create customized models of virtually any device. T-Spice also supports the latest industry models, including the transistor model recently selected as the next standard for simulating future CMOS transistors manufactured at 65 nanometers and below—the Penn State Philips (PSP) model. PSP will simplify the exchange of chip design information and support more accurate digital, analog, and mixed-signal circuit behavior analysis.
  • Enables easy creation of syntax-correct SPICE through a command wizard.
  • Highlights SPICE Syntax through a text editor.
  • Provides Fast, Accurate, and Precise options to enable optimal balance of accuracy and performance.
  • Enables you to link from syntax errors to the SPICE deck by double clicking.
  • Supports Verilog-A for analog behavioral modeling, allowing designers to prove system level designs before doing full device level design.
  • Provides “.alter” command for easy what-if simulations with netlist changes. Perform sophisticated analysis

Sophisticated Analysis
      T-Spice uses superior numerical techniques to achieve convergence for circuits that are often impossible to simulate with other SPICE programs. The types of circuit analysis it performs include:
  • DC analysis (DC Operating Point Analysis & DC Transfer Analysis.)
  • AC analysis               
  • Transient analysis with Gear or trapezoidal integration.
  • Noise analysis.
  • Monte Carlo analysis over unlimited variables and trials.
  • Virtual measurements with functions for timing, error, and statistical analysis.
  • Parameter sweeping using linear, log, discrete value, or external file data sweeps.
  • Transient Analysis, Power-up Mode.
