VHDL (I think it stands for Verilog Hardware Design Language) is a digital electronics definition language, it is used to make hardware with or to program computer circuits which have flexible structure such as fpga's or Xilinx type of chips.

This is to remind me to when I get to the possibility of writing some example tcl generator scripts with an actual Xilinx coolrunner Chip and devenv around to examplify the possible use of tcl and also bwise to automatically generate computer circuits which then via vhdl can be actualized. I've made moderate complexity circuitry which works, and there are applications where it is handy to have a tcl in the loop, and certainly to have a general enough graph editor around.

A (small) xilinx or altera CPLD (Complex Programmable Logic Device) could be used as an alternative to the circuitry in the wiki page LED display driven by the parallel port under tcl control and other circuits connected with Tcl/Tk programs. There are about $50 (50 euro) kits with quite capable devices on a board with connectors and a progammer environment available for web purchase, they work neat.
