4-Bit ALU Circuit Glitch Reduction for Power

Optimization For ELEC 6270 Dr. Vishwani D. Agrawal

By Hunter Thorington Fall 2015

Abstract— ELEC 6270 is an elective offered by Auburn

University’s Dr. Vishwani D. Agrawal. This paper concludes a

semester’s worth of studies in low power circuit design. The

project I was tasked with was: “Redesign a 4-bit ALU circuit for

glitch reduction and examine its power saving”. In this final

semester project, I developed my own VHDL model of a simple

ALU and synthesized this design using Leonardo Spectrum.

Following synthesis, I used the PTM High Performance 45nm

Metal Gate model provided. After applying the model to the

netlist, the design was simulated for a base line. Following initial

characterization of the circuit, the circuit was enhanced for glitch

reduction and low power operation by adding buffers on non-

critical paths. The results show a marked 27% decrease in power

consumption for the applied test vector.

I. INTRODUCTION

This report was written for ELEC 6270 Low Power Design of Electronic Circuits for Dr. Vishwani D. Agrawal. This class focused on the design of digital circuit systems for reduced power consumption, power analysis algorithsm, low power MOS technologies, low power design architectures for FPGA, memory and microprocessors and reduction of power in testing of circuits. The project I was assigned was “Redesign a 4-bit ALU circuit for glitch reduction and examine its power saving”.

II. PROJECT BACKGROUND

A. Glitch Reduction

Circuit power is all about Dynamic Power. Dynamic power

or 𝐶𝑉2

2 , is the amount of power consumed by each gate each

time a transistion occurs. A glitch is defined as any

intermediate change of state of a signal, whether from high

to low or low to high during signal propagation before the

final value is reached. These glitches cause unwanted power

consumption.

B. Boolean Gate Single Transition Theorem

This theorem states that for correct operation with minimum

energy consumption, a Boolean gate much produce no more

than one event per transition. This means that for optimal

power reduction signal arriving at the input of a Boolean

gate much either arrive at the same time (assuming internal

Boolean gate delays are equal) or arrive at nearly the same

time in order to produce a single synchronized transition at

the output of the gate. If each and every gate in the circuit is

held to this theorem the circuit will have minimized power

consumption due to glitches.

C. Differential Path Delays

A multi-input gate will inevitably have differential path

delay. This delay occurs when the path from one input to the

output respective to another input to the same output is

different. Gate with differential path delay inherently

introduce glitch power consumption into the circuit. Figure

1. Shows the glitch caused by a multi-input gate with

differential path delay.

Figure 1. Differential Path Delay

In this figure The input A precedes the response of the gate

to input B which lags by one time period, this produces a

momentary high glitch on the output. This high output draws

Figure 2. Glitch Reduced Using a Buffer Delay

power from the power supply, but is wasted because it soon

returns to the expected value 0. Figure 2 demonstrates that

by placing a delay buffer on input A this issue can be

reduced. Notice in Figure 2 how the glitch is minimized.

Therefore, to ensure glitch reduction, delay A, the input

delay must be less than the delay B – delay A. This is

represented by the equation d < DPD.

D. Delay Balance Method

The buffer enhanced differential delay method can be extended

to circuit wide glitch reduction. The balanced delay method

treats the entire circuit as an effectively large Boolean gate, but

rather than have delay buffers external to the gate the buffers

are internal. Delay buffers are inserted on non-critical paths in

the circuit to delay their response to be in time with the critical

path. If this method is followed for all non-critical paths through

the circuit, all paths will have the same delay. This results

creates a circuit with minimal glitch power loss.

E. Gate Delay Mathmatical Glitch Suppression

Once can define gate delay, the time taken for a signal to propagate from input to output as di. The time differential for each

input can be defined as ti the earlies arriving signal, and Ti the latest arriving signal. To ensure a glitch is suppressed Ti – ti < di

F. Linear Programing Buffer Delay Minimization

To achieve near optimal power reduction, the minimum

number of buffers must be used. While this criterion is

nonlinear, one can minimize the sum of the total buffer delays.

By minimizing total buffer delay one ensures that a near

optimal number of buffers are inserted into the circuit and draw

no more power than necessary to reduce glitch power

consumption. To many buffers (each drawing power

themselves) can increase power consumption rather than

reduce.

G. ALU 74181 Example

The slides provided example results from a previous student of this project. The project took a 74181 ALU, an industry standard DIP package ALU. The circuit was modified in an undisclosed manner and achieved an average of 21% power reduction. I began my design work for this project by studying the 74181 circuit and preparing to optimize the 74181’s design for glitch reduction. This proved to be a difficult task to large size of the 74181 nearing 75 gates. Also, the circuit schematic would have to be drawn by hand in Design Architect to get a base line. Due to time constraints, I decided to design my own ALU with fewer functions and write it in VHDL allowing it to be synthesized into a gate-level model with which I could then modify.

III. PROJECT DESIGN

A. VHDL Model of 4-Bit ALU

The 4-Bit ALU model for this project was written in VHDL.

The ALU has 4 functions add, subtract, add one, and subtract

one. This design could clearly be extended to a larger design

but was out of scope for this project. The ALU has two inputs

A and B which are the two 4 bit unsigned arguments. The output

is a 4 bit vector F. The function of the ALU is selected by setting

the bus S.

entity alu is

port( Clk : in std_logic; --clock signal

A,B : in unsigned(3 downto 0); --input operands

S : in unsigned(1 downto 0); --Operation to be performed

F : out unsigned(3 downto 0) --output of ALU

);

end alu;

architecture Behavioral of alu is

signal t1,t2,t3: unsigned(3 downto 0) := (others => '0');

begin

t1<= A;

t2<= B;

F<= t3;

process(Clk)

begin

if(rising_edge(Clk)) then --Do the calculation at the positive

edge of clock cycle.

case S is

when "00" =>

t3<= t1 + t2; --addition

when "01" =>

t3<= t1 - t2; --subtraction

when "10" =>

t3<= t1 - 1; --sub 1

when "11" =>

t3<= t1 + 1; --add 1

when others =>

NULL;

end case;

end if;

end process;

end Behavioral;

B. Synthesis using Leonardo Spectrum

The circuit was synthesized using Leonardo Spectrum into

TSMC 035 design package for 35nm operation. The resulting

circuit contained 26 block level gates and 54 total gates.

Leonardo defined the critical path as follows and featured a

1.11ns delay time.

C. Vector Selection

HSPICE was used to simulate the circuit by applying a test

vector set. The test vector set I used contained 1024 test

vectors. This represented every possible input combination

one time for each operation. These vectors were run 5ns

apart for a total of 5120ns to profile the circuit for power

consumption.

D. Power Analysis Initial Circuit

The power analayis for the un modified circuit was run using

HSPICE. The result showed 336uW used before glitch

reduction.

E. Glitch Reduction Design Using Buffer Delays

As given earlier, the critical path had a delay of 1.11ns. Using

the gate level model of the circuit I determined 8 paths that

could be optimized using buffer delays to bring their total path

delay near 1.11 ns. These buffer delays are as follows:

Path 1: S[1] ix129, ix1, ix7, ix136, ix134, new buffer, ix146, ix155, regt33

Buffer delay added 0.32ns

Path 2: S[0], ix129, ix127, ix7, new buffer, ix134, ix146, ix155,ix89,reg33

Buffer delay added 0.33ns

Path 3: S[1], new buffer, ix134, ix146, ix155, ix99, reg33

Buffer delay added 0.33ns

Path 4: A[0], new buffer, ix11, regt30,

Buffer delay added 0.93ns

Path 5: S[1], ix127,ix7,ix9, new buffer,ix11

Buffer delay added 0.90ns

Path 6: A[1], ix9,new buffer, ix87,ix63,reg32

Buffer delay added 0.27ns

Path 7: S[1], ix35, new buffer, ix37,reg31

Buffer delay added 0.35ns

Path 8: S[1], ix134, new buffer, ix37,reg31

HSPICE. The result showed 336uW used before glitch

reduction.

IV. CONCLUSION

A. Results

This simple ALU designed allowed me to tune in really good

results. Using a minimal number of delay buffers, 8, on select

non critical paths allow me to make 9 selected paths through the

circuit has similar delays. This resulted in fewer glitches and

decreased power consumption. While not all paths were

optimized and the number of buffers and total buffer delay was

not optimized using linear programming I feel this a good

results considering the time constraints and project scope.

Please see the following pages and appendixes for addition

evidence of completed work.

B. Overall

This project and class was quite enjoyable. I really learned a lot

about power reduction and how complex and simple it can be

at the same time. Low power devices are the next generation

devices that will be made. Battery power and mobile devices

rely heavily on reduced power consumption. The design and

analysis techniques learned in this class are very applicable to

the job market today. I feel I have come away with actionable

knowledge ready to be applied and expanded on in my career.
