Implement an SRAM circuit that has a 32 bytes with its associated decoder and multiplexer. The

SRAM memory must have the following properties:

1- Addresses are from 0x8000 to 0x801F.

2- You can read and write one byte at a time.

3- The are special output signals that are required. They are listed in the table below.

Signal code Signal name Desciption

Z Zeros If all the bits in the sram are 0

O Ones If all the bits in the sram are 1

L Lower Ones

Upper Zeros

If 16 lower bytes of the sram are ones and the 16 upper parts of

the sram are zeros.

U Lower

Zeros Upper

Ones

If 16 lower bytes of the sram are zeros and the 16 upper parts of

the sram are ones.

Assume all nMOS and pMOS has (W= 4λ, L=2λ) unless it is nessesary to change sizing. The inputs

and outputs of your design are as follows:

Inputs: Outputs:

An unsigned 5-bit Address A (a4: a0) An unsigned 8-bit Data D (d7: d0)

An unsigned 8-bit Data D (d7: d0) Z,O,L,U.

Read, Write signals.

Phi1, Phi1_b, Phi2, Phi2_b for clocking.

Any other necessary outputs

 Part 3: Implement your design using Magic VLSI layout tool to generate your project layout
http://opencircuitdesign.com/magic/

 Part 4: Test your design using irsim to simulate your project.

Deliverables:

1- One PDF that contains the following sections:

 Introduction

 Problem statement and specifications

 Motivation

 Solution design using a logic design tool that you studied in the previous logic design courses
and HDL tool

Phase 2:

(by using logsim)
 Part 2: List in a table the required components with their respective input and output labels
structural method

 Part 1: Verify the design using a logic design tool and an HDL tool (using active HDL) using

Phase 1:
Requirement:

Any other necessary inputs

A common VDD and common GND lines

 Stick diagram for each component of your design. The building blocks components are
enough.

 Testing strategy and results: they should show instructions to simulate and verify your design,
by including Linux terminal commands for Magic and Irsim used to run your project with

few different inputs.

2- A compressed folder containing:

 Source code and layout.
