Objectives: design efficient VLSI systems that has: Circuit Speed Power consumption Design Area (high ) ( low ) ( low ) VLSI Design Flow 1. Digital VLSI Design Lecture 1: Introduction Semester A, 2016-17 Lecturer: Dr. Adam Teman. These tools have the flexibility to import or export different types of files. To succeed in the VLSI design flow process, one must have a robust and silicon-proven flow, a good understanding of the chip specifications and constraints, and absolute mastery over the required EDA tools (and their reports). VLSI Design Flow. Motivation 1964 –The Integrated Circuit 1971 –The Intel 4004 2,300 Transistors 1992 –The Intel 486DX2 ... Chip Design Flow 1 Motivation 2 Course Logistics 3 Building a Chip 4 Design Automation 5 Standard Cell Design Flow •Behavior – define function and specification – hardware algorithms •Structural: Front end design – verilog coding – simulation – logic synthesis – simulation again – verified by FPGA testing •Physical: Back end design – floor planning, placement, routing … 4. Specifications. VLSI design flow is not exactly a push-button process. Design architecture. The chip design includes different types of processing steps to finish the entire flow. Department of Electronics and Communication Engineering, VBIT SYLLABUS UNIT II VLSI CIRCUIT DESIGN PROCESSES: VLSI Design Flow, MOS Layers, Stick Diagrams, Design Rules and Layout, 2 m CMOS Design rules for wires, Contacts and Transistors Layout Diagrams for NMOS and CMOS Inverters and Gates, Scaling of MOS circuits. https://www.slideshare.net/godbhati/vlsi-design-summer-training-ppt by Pravriti • November 20, 2017 • 1 Comment. The VLSI design cycle starts with a formal specification of a VLSI chip, follows a series of steps, and eventually produces a packaged chip. Idea (need) 2. Our emphasis is on the physical design step of the VLSI design cycle. For each and every step, the design process requires a dedicated EDA tool. 3. https://www.slideshare.net/IftikarAlam1/vlsi-design-26179323 A typical design cycle may be represented by the flow chart shown in Figure.
