C Programs - Hello World

I am uploading source code of few commonly used functions. The programs are written in C and I used gcc to compile and test these programs. I hope you find them useful. As it is always the case, I am starting with hello world 
 #include<stdlib.h>  
 #include<stdio.h>  
 void main()  
 {  
  printf("HEllo World");  
 }

Setting up atalanta ATPG to work on Linux

Atalanta is an ATPG tool that is used to generate test patterns for combinational circuits. atalanta is a windows executable file. I am using Atalanta ATPG tool to generate the test patterns required for generating the Transition fault Test patterns RUNNING ATALANTA (LINUX) You need to have WINE installed to run windows executable binary. Created a symbolic link in the usr/bin to the atalanta.exe, name of the link s atalanta. (not necessary if you do not have root privilages) chmod u+x /place/atalanta/atalanta.exe cd /usr/bin sudo ln -s /place/atalanta/atalanta.exe ./atalanta COMMAND TO RUN ATALANTA atalanta [option] filename //put this in a shell script

Generating 16k ROM using Xilinx IP COREGEN and simulating it in modelsim

The instruction ROM is an IP Core. so before interfacing with the open8, it has to be generated. The method of generating and simulating a ROM Xilinx IP Core is described here. FIND ALL THE FILES HERE 1. app.coe (the initialization file) 2. rom_16k_core.vhd 3. rom_16k_core.vho 4. rom_16k_core.xco 5. top_level.vhd 6. do_memgen.do Creation of the ROM Xilinx 10.1 1. open ISE 2. create a new project 3. tools -> core generator(12.1) (or right click on the device and add a new file 10.1) 4. In the IP catalog -> Memory and storage elements -> RAM and ROM 5. double click on block memory generator, A new window opens 6. In the new window select single port ROM click next, Write first mode 7. Select Read Width = 8 and Read Depth = 16384 for 16K ROM -> next 8. The output ports are unregistered, load initialization COE if required -> next 9. No need to use the Reset pin -> next 10. Generate. (takes a little time then shows successfully generated) This
