Designing a VLSI IC
http//www.amperevlsi.com/

• The process includes designing, starting from
  gates to design for testability. Backend design
  comprises of CMOS library design and its
  characterization. It also covers physical design
  and fault simulation. The entire design procedure
  follows a step by step approachProblem
  Specification
• It is a high-level representation of the system.
  The major parameters are performance,
  functionality, physical dimensions, fabrication
  technology and design techniques. It has to be a
  tradeoff between market requirements, the
  available technology and the economic viability
  of the design.

Architecture DefinitionBasic specifications like
floating point units, which system to use, like
reduced instruction set computer (RISC) or
complex instruction set computer (CISC), number
of ALUs cache size etc.

• Functional Design
• Defines the major functional units of the system
  and hence facilitates the identification of
  interconnect requirements between units, the
  physical and electrical specifications of each
  unit.
• Logic Design
• Boolean expressions, control flow, word width,
  register allocation etc. are developed and the
  outcome are the register transfer level (RTL)
  description. HDLs implement the RTL description
  onto a system.

Circuit DesignWhile the logic design gives the
simplified implementation of the logic,the
realization of the circuit in the form of a
netlist is done in this step. The netlist
consists of gates, transistors and various
interconnects. This again is a software step and
the outcome is checked via simulation.

• Physical Design
• The conversion of the netlist into its
  geometrical representation is done in this step
  and the result is called a layout. This step
  follows some predefined fixed rules like the
  lambda rules which provide the exact details of
  the size, ratio and spacing between components.
• Etching
• It removes material selectively from the surface
  of wafer to create patterns. An etching mask
  protects some parts of the material. Additional
  chemicals or plasma removes the remaining
  photoresist. An inspection makes sure the
  transference of the image from mask to the top
  layer of wafer.
