Control Of Automatic Vehicle wash m/c

Having those many number of io's, i don't know if a CPLD would make the cut.

but if you have no idea about how big your project is gonna be, then just jot down what kinda logic you'll be using and the components, as mentioned in the previous post. try looking for a similar system (or a system having almost similar components) and check the device they are using.

The best way to be generate the entire project on QII or Xilinx and check the fitter report on utilization... =P
