1.1 Evolution of Computer-Aided Digital Design

Digital circuit design has evolved rapidly over the last 25 years. The earliest digital

circuits were designed with vacuum tubes and transistors. Integrated circuits were then

invented where logic gates were placed on a single chip. The first integrated circuit (IC)

chips were SSI (Small Scale Integration) chips where the gate count was very small. As

technologies became sophisticated, designers were able to place circuits with hundreds of

gates on a chip. These chips were called MSI (Medium Scale Integration) chips. With the

advent of LSI (Large Scale Integration), designers could put thousands of gates on a

single chip. At this point, design processes started getting very complicated, and

designers felt the need to automate these processes. Electronic Design Automation (EDA)

techniques began to evolve. Chip designers began to use circuit and logic simulation

techniques to verify the functionality of building blocks of the order of about 100

transistors. The circuits were still tested on the breadboard, and the layout was done on

paper or by hand on a graphic computer terminal.

[1] The earlier edition of the book used the term CAD tools. Technically, the term

Computer-Aided Design (CAD) tools refers to back-end tools that perform functions

related to place and route, and layout of the chip . The term Computer-Aided Engineering

(CAE) tools refers to tools that are used for front-end processes such HDL simulation,

logic synthesis, and timing analysis. Designers used the terms CAD and CAE

interchangeably. Today, the term Electronic Design Automation is used for both CAD

and CAE. For the sake of simplicity, in this book, we will refer to all design tools as EDA

tools.

With the advent of VLSI (Very Large Scale Integration) technology, designers could

design single chips with more than 100,000 transistors. Because of the complexity of

these circuits, it was not possible to verify these circuits on a breadboard. Computer-

aided techniques became critical for verification and design of VLSI digital circuits.

Computer programs to do automatic placement and routing of circuit layouts also became

popular. The designers were now building gate-level digital circuits manually on graphic

terminals. They would build small building blocks and then derive higher-level blocks

from them. This process would continue until they had built the top-level block. Logic

simulators came into existence to verify the functionality of these circuits before they

were fabricated on chip.

As designs got larger and more complex, logic simulation assumed an important role in

the design process. Designers could iron out functional bugs in the architecture before the

chip was designed further.

1.2 Emergence of HDLs

For a long time, programming languages such as FORTRAN, Pascal, and C were being

used to describe computer programs that were sequential in nature. Similarly, in the

digital design field, designers felt the need for a standard language to describe digital

circuits. Thus, Hardware Description Languages (HDLs) came into existence. HDLs

allowed the designers to model the concurrency of processes found in hardware elements.

Hardware description languages such as Verilog HDL and VHDL became popular.

Verilog HDL originated in 1983 at Gateway Design Automation. Later, VHDL was

developed under contract from DARPA. Both Verilog and VHDL simulators to simulate

large digital circuits quickly gained acceptance from designers.

Even though HDLs were popular for logic verification, designers had to manually

translate the HDL-based design into a schematic circuit with interconnections between

gates. The advent of logic synthesis in the late 1980s changed the design methodology

radically. Digital circuits could be described at a register transfer level (RTL) by use of

an HDL. Thus, the designer had to specify how the data flows between registers and how

the design processes the data. The details of gates and their interconnections to

implement the circuit were automatically extracted by logic synthesis tools from the RTL

description.

Thus, logic synthesis pushed the HDLs into the forefront of digital design. Designers no

longer had to manually place gates to build digital circuits. They could describe complex

circuits at an abstract level in terms of functionality and data flow by designing those

circuits in HDLs. Logic synthesis tools would implement the specified functionality in

terms of gates and gate interconnections.

HDLs also began to be used for system-level design. HDLs were used for simulation of

system boards, interconnect buses, FPGAs (Field Programmable Gate Arrays), and PALs

(Programmable Array Logic). A common approach is to design each IC chip, using an

HDL, and then verify system functionality via simulation.

Today, Verilog HDL is an accepted IEEE standard. In 1995, the original standard IEEE

1364-1995 was approved. IEEE 1364-2001 is the latest Verilog HDL standard that made

significant improvements to the original standard.
