Course Overview
Custom layout training is 5.5 months course targeted for BTech, BE, MTech, ME, diploma graduates and experienced engineers planning to pursue career as a layout design engineer. Training will focus on all the aspects of layout including Analog layout, Memory layout, Standard cell layout and IO layout. Custom layout design course ensures that a fresher/experienced engineer is prepared on all the essential aspects of Custom layout including ASIC flow, VLSI Design flow, Digital Design concepts, CMOS basics, FinFET basics, various memory architectures, Standard cell, IO’s and detailed analog layout techniques. Course also includes training on UNIX, revision management, scripting and soft skill for effective interview performance.
Course starts with detailed sessions on semiconductors, Ohms law, Kirchoff law’s, Diode-operation, MOSFET’s, MOSEFT operations, second order effects, FinFET’s, and detailed fabrication process, which is followed by assignments and hands on projects.
Course will also include detailed sessions on layout basics, hands on standard cell layouts, IO layout and memory layout for different architectures. Followed by various analog layout techniques with detailed discussion on Mismatches & Matching, Noises & Coupling, various failure mechanisms which includes Electro migration, IR drop, LOD & Stress effects, WPE, Antenna Effects, Latch up, ESD. Course includes 20+ detailed labs & assignments covering all aspects of custom layout with multiple hands on projects.
Analog layout techniques will involve multiple hands on projects covering various concepts such as common centroid, inter digitation, resistor matching, capacitor matching and opamp circuits, current mirrors, PLL’s, ADC’s, DAC’s, Bandgap, Temperature sensors & Biases -> Current & Voltage bias lines, Large drivers, LNA & Mixers, and Sense amplifier & Bit cell development.

Projects are the most significant part of any engineers(both fresher and experienced) resume. It is the projects that differentiate your resume from other resumes, which essentially helps your chances of getting through the interviews.
Below is the list of projects student will be doing as part of six months training. Student will be doing all these projects from scratch. These projects will provide student with expertise on par with a 2 to 3 years experienced engineer, in terms of all the skill set required. Student can work on additional projects to enhance resume for experienced job role.
By working on below projects, student will get familiar with:
- Complete layout flow including
- Floor planning
- Schematic
- Layout
- Physical verification
Description : Schematic, Layout design and verification for standard cell for NOT, NAND, NOR, AND, OR gate and Buffer.
Role : Layout Design and Layout Verification.
