Unit 6: Introduction to ASIC, FPGA, PLD 16 marks
Different software’s related to VHDL. • Xilinx, Aldec, Cadence, Mentor Graphics, Synopsys.
advantages of PLD’s. • 1) Inexpensive at low quantities. • 2) The design inside the chip is flexible, so a change in the logic does not require any rewiring of the board. • 3) PLDs are often used for address decoding.
Two examples of CPLD and FPGA. Write one application of CPLD and FPGA. • Example of CPLD: • 1. Xilinx XC 9500 CPLD • 2. CPLD ATF 1502 ASV Examples of FPGA: • 1. 5 K – 50 K Gates Coprocessor FPGA with Free RAM • 2. XILINX XC 4000
Applications of CPLD: 1. Complex programmable logic devices are ideal for high performance, critical control applications. 2. CPLD can be used in digital designs to perform the various functions. 3. Generally, these are used in small design applications like address decoding. 4. CPLDs are frequently used many applications like in cost sensitive, battery operated portable devices due to its low size and usage of low power.
