Tevatron Technologies is a private company focused on VLSI design, FPGA-based design, and embedded systems. Their vision is to be an end-to-end provider for electronics system design and manufacturing. The company hosted an industrial training seminar on RTL design, Verilog, and FPGA design. The seminar covered topics like VHDL vs. Verilog, Verilog coding styles, data types, constructs, RTL coding guidelines, and FPGA architecture. VLSI allows integrating millions of electronic components on a small chip area and is used for applications like processors, memory, and specialized chips.

3.  Unique PS2 Based Approach:

4. VLSI introduction : Objectives
introduction :
 AVLSI (Very Large Scale Integration) system integrates millions of
“electronic components” in a small area (few mm2  few cm2).
Objectives:
design “efficient”VLSI systems that has:
• Circuit Speed (high )
• Power consumption ( low )
• Design Area ( low )

6. VHDL VERILOG
 Not case sensitive.
 Difficult to learn.
 Based on pascal & ada.
 Case sensitive.
 Easy to learn.

HDL – Hardware Description Language
ƒ
A programming language that can describe the
functionality and timing of the hardware.
Types of HDL
• VHDL (VHSIC Hardware Description Language)
• VERILOG
• SYSTEMVERILOG
Difference

7. Style of modeling
1.Data flow
-if designer is concern about flow of data in design, concurrent
statement is used here.
2.Behavioral
- if designer is not concern about h/w and flow of data rather
concerned about the functionality of designing
3.gate
-if designer is concerned about h/w.
4. Switch level
- it is transistor level of modeling used in analog mixed
signal(AMS)’
Basic Verilog HDL Code

8. Data types in Verilog
1.Register: can store value
1. Reg
2.Integer
3.Real
4.Time
2. Net: can’t store value
1. wire
2. wand
3. wor
4. triac

9. Construct Types
1. Synthesizable
1. Can get h/w here
2. Non synthesizable
Can’t get h/w
*for verification purpose, synthesizable or non synthesizable both can be
used.

10. Verilog Methods
1. Task: a) specific job again and again over certain period
b)May or may not have any input argument
c)May contain delay, waiting or event control statement.
2. Function: a) specific job again and again over any period
b)Should have atleast one input argument
c)Should not contain delay, waiting or event control statement
*Task and function are synthesizable construct.

11. RTL coding guidelines
 Always use non-blocking assignment statement to model
sequential logic.
 Always use blocking assignment statement to model
combinational logic.
 Use NBA statement to model latches.
 For mixing of combinational and sequential use NBA.
 Use separate always block for for different signals.
 Use $strobe to check final value of signal.

15. System Task
System tasks are available to handle simple I/O and various design measurement functions during simulation. All system
tasks are prefixed with $ to distinguish them from user tasks and functions.
 $display - Print to screen a line followed by an automatic newline.
 $write - Write to screen a line without the newline.
 $swrite - Print to variable a line without the newline.
 $sscanf - Read from variable a format-specified string. (*Verilog-2001)
 $fopen - Open a handle to a file (read or write)
 $fdisplay - Write to file a line followed by an automatic newline.
 $fwrite - Write to file a line without the newline.
 $fscanf - Read from file a format-specified string. (*Verilog-2001)
 $fclose - Close and release an open file handle.

16. F0RK/JOIN
The fork/join pair are used by Verilog to create parallel processes. All
statements (or blocks) between a fork/join pair begin execution
simultaneously upon execution flow hitting the fork. Execution continues
after the join upon completion of the longest running statement or block
between the fork and join.

17. VLSI Applications
 VLSI is an implementation technology for electronic circuitry - analogue or digital
 It is concerned with forming a pattern of interconnected switches and gates on the surface of
a crystal of semiconductor
 Microprocessors
 personal computers
 microcontrollers
 Memory - DRAM / SRAM
 Special Purpose Processors - ASICS (CD players, DSP applications)
 Optical Switches
 Has made highly sophisticated control systems mass-producable and therefore cheap

What is an FPGA?
Block
RAMs
The FPGA is an integrated circuit that contains many (64 to over 10,000)
identical logic cells that can be viewed as standard components. Each
logic cell can independently take on any one of a limited set of
personalities. The individual cells are interconnected by a matrix of
wires and programmable switches. A user's design is implemented by
specifying the simple logic function for each cell and selectively closing
the switches in the interconnect matrix. The array of logic cells and
interconnect form a fabric of basic building blocks for logic
circuits. Complex designs are created by combining these basic blocks
to create the desired circuit.
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after
manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description
language (HDL), FPGAs can be used to implement any logical function that an ASIC could perform.
Implementation includes many phases
 Translate : Merge multiple design files into a single netlist
 Map : Group Logical symbols from the netlist (Gates) into physical
components (CLB s and IOBs )
 Place & Route : Place components onto the chip, connect them and
extracts timing data into reports
 Timing (Sim) : Generate a back annotated netlist for timing
simulation tools
 Configure : Generate a bit stream for device configuration

19. Vlsi is suitabale for fabrication of larger number
of components on a single chip.
VHDL/VERILOG is used for digital circuit
designing and to validate the design and check
the design specification.
