Part – A: VLSI Digital Design
Experiments to be done using
1. CADENCE/SYNOPSIS/MENTOR GRAPHICS/TANNER or any other equivalent Tool
2. FPGA/CPLD Boards with Xilinx or any other equivalent
ASIC-Digital Design Flow
I. Write Verilog Code for the following circuits and their Test Bench for verification, observe the wave technological library (constraints to be given). Do the initial timing verification with gate level simulation.
1. An inverter, Buffer, Transmission gate and basic gates
2. Flip flop - RS, D, JK, MS, T
3. 4-bit counter [Synchronous & Asynchronous counter]
Note: For the set of experiments listed above, students can make the following flow as a study:
- Core Constrained flow
- Creation of I/O pad frame
- Use the created I/O pad frame for Pad constrained design.
- CTS flow Only for designs which have clock
FPGA DIGITAL DESIGN
VLSI Front End Design programs:
Programming can be done using any compiler. Down load the programs on FPGA/CPLD boards and use pattern generator (32 channels and logic analyzer )/Chipscope pro apart from verification by simulation
1.Write Verilog code for the design of 8-bit
i. Carry Ripple Adder
ii. Carry Look Ahead adder
iii. Carry Skip Adder
2.Write Verilog Code for 8-bit
i.Array Multiplication (Signed and Unsigned)
ii. Booth Multiplication (Radix-4)
3.Write Verilog code for 4/8-bit
i.Magnitude Comparator
ii. LFSR iii. Parity Generator
iv. Universal Shift Register
