Overall aims and purpose

This module aims to introduce the concepts and design techniques of Very Large Scale Integration systems through a study of Application Specific Integrated Circuits (ASICs), with particular emphasis on Field Programmable Gate Arrays (FPGAs).

Course content

• ASIC technologies: fully custom, standard cell, gate array and programmable ASICs. Influence of total cost on choice of ASIC type.

• Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs). Programming technology. CMOS logic cells. Coarse-grained vs fine-grained architectures. Routing and Timing. I/O cells. Embedded microprocessors.

• ASIC Design Software, design flows and design entry methods: Schematic Entry, Hardware Description Languages (HDLs): VHDL.

• Behavioural and structural models. Event-driven simulation. Logic Synthesis: limitations of HDL based logic synthesis.

• Register Transfer Level (RTL) design: datapath, High Level State Machines (HSM), operator binding, operator scheduling, area-time trade-offs.
