You have now successfully programmed your first CoolRunner-II CPLD.
The challenge is to get the design working on the board so that the changing sequence of
lights can be viewed. The design in the CPLD has the correct pinout but ,unfortunately,
there are two problems. The oscillator on the board is running way too fast for the human
eye to see, and there are not enough LEDs on the board to display the lighting sequence.
There are several ways to solve the problem and you are at liberty to choose any method
you prefer. Maybe you want to divide the oscillator frequency, maybe you want to source
a slower oscillator. You are free to move the signals to different pins using the method
shown in this chapter.
Enjoy!
With sources for Synthesis/Implementation displayed in the Source window,
double-click on Configure Device (iMPACT) in the Process window (you may
have to click the plus sign adjacent to Generate Programming File).
Right-click on the Xilinx XC2C256 icon that appears in the iMPACT window and select
Program.
The design will now download into the device.
