1. INTRODUCING MICROWIND

2. www.microwind.org WHAT IS MICROWIND
Microwind is a unique educational tool for designing nano-CMOS cells
Microwind may be configured in any technology from 1.2µm downto 14nm
Microwind illustrates 2D, 3D aspects of Ics
Microwind simulates cells & blocks using embedded simulator

3. 2006 – New Delhi 2006 – Pune www.microwind.org WHAT IS MICROWIND
Books on CMOS basic & advanced design have been written by E. Sicard, S. Ben Dhia and published by Tata-McGrawHill in 2006
Microwind has been successfully deployed in India and in some universities around the world by ni2designs
2006 – Pune

4. Acceptable for simulators
MOS MODELS
Microwind uses Level1, Level3, and a simplified version of BSIM4, adapted to FinFET
“Typically, FinFET models have over 1,000 parameters per transistor, and more than 20,000 lines of C code”
BSIM in Microwind uses 25 parameters and 250 lines of code… but makes many simplifications

7. MICROWIND LAMBDA-BASED DESIGN
Gate pitch
Microwind works in lambda units (λ)
Not optimum layout but independent of technology
Design rules have remained nearly the same for 20 years
λ is nearly half of technology (8nm in 14-nm node)
Channel length is 2 λ
Minimum gate pitch is 8 λ (2+6)
Minimum metal pitch is 6 λ (3+3)

Microwind DRC only checks around 100 basic design rules
In 14-nm technology, more than 2500 design rules have been listed in the design kit
Layouts cannot be fabricated without full DRC
