VHDL Implementation of Interrupt Controller Aathira. • Used Reconfigurable Computing to solve a problem of identifying damaged integrated circuits in only one device instead of building a specific tester circuit for each one. The design we have chosen for this exercise is an electric piano. • The second part is open book (books and notes are allowed). Master FPGA digital system design and implementation with Verilog and VHDL. 4 SIMULATION RESULTS A software program using the VHDL language was developed, for synthesizing the architecture, using the Xilinx Foundation software v3. • Developed an automatic digital integrated circuits (ICs) tester based on a hardware description language. , is a must.
