The laboratory consists of experiments that illustrate the concepts of digital system design thus providing the students with an opportunity to build and test real systems. Lab exercises make use of Xilinx ISE tool chain and SPICE tool chain, which is a powerful state-of-art CAD tool for designing and implementing digital systems on Field Programmable Gate Array (FPGA) boards. The system consists of an integrated set of tools that allows one to capture designs with schematic entry or a Hardware Description Language (HDL), and simulate, implement and test these designs. The use of programmable logic devices takes away the tedious task of wire wrapping individual gates and allows one to concentrate on the creative part of designing the circuits. This lab has Tanner EDA Tool, Universal Trainer Kit with FPGA Module, Xilinx 12.1.
