Introduction: ASIC Design Flow

ASIC (Application-Specific Integrated Circuit) design is a complex process that involves creating custom integrated circuits tailored to specific applications. This training on “ASIC Design Flow” will guide participants through the complete ASIC design process, from specification and design entry to verification and manufacturing. The course covers all stages of the design flow, including RTL design, synthesis, physical design, and testing, equipping participants with the skills needed to successfully develop and implement ASICs.

Prerequisites:

1. Basic knowledge of digital logic design: Understanding of combinational and sequential logic circuits.
2. Familiarity with HDL (Hardware Description Languages): Knowledge of Verilog or VHDL.
3. Understanding of semiconductor technology: Basic knowledge of CMOS technology and transistor operation.
4. Experience with EDA tools: Familiarity with Electronic Design Automation (EDA) tools is beneficial but not mandatory.
