  • Knowledge on physical design flow will be good to have
  • If not, no worries. This course will take you from basics to advanced in a structured manner and create an interest in physical design world

Static timing analysis comprises broadly for timing checks, constraints and library. Having all of them in a single course makes it bulky. So we decided to have it in 3 parts and this is part I - Essential timing checks. This course will give an eagle's eye to every timing check that is being performed in current industries for sign-off. This will also introduce you to basic terminologies for timing, which are needed for advanced courses on STA.

Timing comes at every step of physical design flow, but in this course, we primarily focus on signoff timing i.e. looking into each and every corner of design for any timing violations

The course starts from very basic and gradually takes you to an advanced level at an intermediate pace. So no questions on you missing any details

Hope you enjoy learning this course in the same way we enjoyed making them.

Happy Learning !!

Who is the target audience?
  • Course starts from basic timing path to advanced latch checks, so basics of flipflops should be enough

2) Lead Sales Application engineer, Cadence Design systems, Bangalore India, 04/2013-01/17

Hands on with Technology @

1) MSM (mobile station mode chips) - MSM chips are used for CDMA modulation/demodulation. It consists of DSP’s and microprocessors for running applications such as web-browsing, video conferencing, multimedia services, etc.

2) Memory test chips - Memory test chips are used to validate functionality of 28nm custom/compiler memory as well as characterize their timing, power and yield.

3) DDR-PHY test chips - DDR-PHY test chips are basically tested for high speed data transfer

4) Timing and physical design Flow development for 130nm MOSFET technology node till 16nm FinFET technology node.

5) “IR aware STAandLow power STA

6) Analyzed STA engine behavior for design size up to 850 million instance count


1) Research Assistant to Prof. Richard Pinto and Prof. Anil Kottantharayil on “Sub-100nm optimization using Electron Beam Lithography”, which intended to optimize RAITH-150TWO Electron Beam Lithography tool and the process conditions to attain minimum resolution, use the mix-and-match capabilities of the tool for sub-100nm MOSFET fabrication and generate mask plates for feature sizes above 500nm.

2) Research Assistant to with Prof. Madhav Desai, to characterize RTL, generated from C-to-RTL AHIR compiler, in terms of power, performance and area. This was done by passing RTL, generated from AHIR compiler, through standard ASIC tool chain like synthesis and place & route. The resulting netlist out of PNR was characterized using standard software

Now, to be really successful in the field of VLSI and Semiconductors, you need to take the courses in below order:

1) VSD - Physical design flow

2) VSD - Clock tree synthesis - Part 1 & 2

3) VSD - Signal Integrity

4) VSD - Static timing analysis - Part 1 & 2 (Can be taken in between)

5) VSD - Circuit design and SPICE simulations Part 1 & Part 2 (This is the core of VLSI, so you can take it in beginning or end)

6) VLSI - Essential concepts and detailed interview guide (This course is a glimpse of all above courses, but for details of each topic, you need to take course 1) to 5).)

7) VSD - Custom Layout (Can be taken in between) 

8) VSD - Library characterization and modelling - Part 1 (STA-1 and 2, Circuit design and SPICE simulations-1 and 2 are mandatory)
