Synthesis Sign-off STA and LEC

Course Overview:

In todays era complex SoC chips are being realized using CAD automations, of which RTL2GDSII flow is being used extensively during any SoC manufacturing. This has enabled to realize very complex digital design, which starts with the design specification and modeling of design using HDL language. This high level description of design is mapped to its corresponding hardware using automation, known as “Synthesis”, without which it’s near to impossible to design very complex digital circuit. Also, in order to verify that generated hardware with the original HDL description, designer either can choose functional verification using test-cases, but that is not very exhaustive. Hence there is need of other methodology which can effectively verify the design equivalence. This is achieved by formal verification (also know as logical equivalence checking, in short LEC).

Timing is one of the key performance metric of a Chip other than Power, Area and Timing closure is the major milestone which dictates when a chip can be released (tape out)  to the semiconductor foundry for fabrication. Timing Closure is important Skill for a VLSI engineer and knowledge of Timing is essential for most of the Engineers working on ASIC flow. This course is designed for the working VLSI engineers who want to learn / enhance their knowledge on Static Timing Analysis (STA).

The course will be delivered by a Senior VLSI Engineer, who has worked on multiple tape outs for Synthesis, timing closure, Physical Design, LEC. Importance is given to cover the concepts, methodology thoroughly with good emphasis on hands-on training, using Industry standard tool set, with at least 50 % time allocated to lab sessions.

Uniqueness of this Course:

This course offers integrated learning for synthesis, equivalence checking & sign-off STA under one umbrella with exposure Industry standard EDA tools. It’s not only covered the tool aspect but also provides in depth technical knowledge.

What do you get out of this Course?

Synthesis sign-off STA course offers in depth know-how of using design compiler for synthesizing the design modelled in Verilog or VHDL. It also offers the logical equivalence check between the golden & implemented design along-with the timing analysis of synthesized design. It provides the opportunity to learn the synthesis, LEC & timing analysis which is imperative to get the silicon working first hand for the very complex design.

What Opportunities could open up for you?

Having been exposed the to the synthesis, equivalence checking & timing analysis, a participant is well poised to expand its horizon of technical skills which, in turn, assist achieving growth vertically up in technical pyramid, whether he is RTL designer, a verification engineer, PCB design engineer, FPGA engineer or physical implementation engineer (PnR). Having expertise in all aspect of RTL2GDSII flow, particularly synthesis sign-off sta, shall enable you to lead the chip design qualitatively. Also, todays semiconductor industry demands integrated expertise, either as RTL designer, synthesis & STA or synthesis, STA and PnR.

My expectation was to get thorough knowledge of STA. After joining this course things are more clear now and some exposure of LEC. Trainer is having good knowledge of STA concepts. and the supporting examples are also good and related to real scenarios so we can relate it to design. VPN facility was good. It is very user friendly facility that enables us to access tools easily. Overall program was good. It helped me to explore my knowledge.

I have joined this course to gain good practical knowledge on STA and synthesis, by using PT & DC tools. Trainer has very strong technical expertise & course has met all my expectations. Now I am confident enough, to handle some complex STA in day to day work. I could spend extra time on Labs & assignments, because of VPN facility.
