开关、 灯、 和多路复用器-DE2-115

应用背景基于VHDL实现四层电梯的运动，实现电梯的正常运转关键技术VHDL，状态机，编译码器，触发器，比较器。

基于FPGA编写一个时间显示，计数功能，年月显示的程序，(FPGA-based preparation of a time display, counting, years show program,)

Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA port, connects the switches to the LEDs, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 port. This demo how ever does not drive the RS-232 port or the memory. This is a simple design done entirely VHDL not microblaze.
