DIGITAL DESIGN USING VERILOG HDL 


Course Objectives:

This course teahces:

  • Desigining digital circuits, behaviour and RTL modelin of digital circuits usin verilog HDL, verifying these Models and synthesizing RTLmodels to standard cell libraries and FPGAs.
  • Students ain practical experience by designing, modeling, implemeting and verfying several digital circuits.

This course aims to provide students with the understanding of the different technologies related to HDLs, construct, compile and execute Verilog HDL prorams usin provided software tools. Design diital components and circuits that are testable, reusable, and synthesizable.
