    Multiplier and Accumulator in Verilog

    Hi, You cannot call a file inside always block. Please understand what does always block does. If you want the same functionality then instantiate it assign the output of booth_mul signal to ber used in the always block. By this means you can manipulate Thanks, Vivek.S

    Most Efficient means of converting wind energy to electrical energy(230v AC)

    Hi, If the power generation is just for small requirement and not commercial purpose then VAWT gives a good power out with less wind. Check this site:- https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine. In this site General aerodynamics, explains the physics of generating the power.

    Most Efficient means of converting wind energy to electrical energy(230v AC)

    If the wind is not heavy then you can go for vertical axis wind turbines. They do not require as much wind to generate power, thus allowing them to be closer to the ground. So you can experiment with this VAWT which will be suitable for the condition. It will not be efficient to convert to small...
