vhdl tutorial and example


Collection of examples

HDL (Hardware Description Language) based design has established itself as the modern approach to design of digital systems, with VHDL (VHSIC Hardware Description Language) and Verilog HDL being the two dominant HDLs.

examples have been simulated by Aldec ActiveHDL Simulator and Synopsys Design Analyzer, as well as synthesized with Synopsys Design Compiler . Several sequential design examples have been successfully tested on Xilinx Foundation Software and FPGA/CPLD board.

This is for the vhdl beginners,

donot go through details, if you are expert in vhdl

    Hi guys, i’m working with the lab , design a fir filter has 16 bit input, 16 bit output and 32 tap with two case
    case 1 : all coeficient equal 1
    case 2 : all coeficient less than 1

    i have just studyed vhdl , so can you give me some code !
    thanks
