Synthesis Sign-off STA and LEC

Course Overview:

In today’s era, complex SoC chips are being realized using complex VLSI(EDA) tools, of which RTL2GDSII flow is being used extensively during any SoC manufacturing. This has enabled the realization of very complex digital designs, which starts with 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 circuits.

In order to verify the generated hardware with the original HDL description, the designer can choose functional verification using test-cases, but that is not very exhaustive. Hence there is need for other methodology which can effectively verify the design equivalence. This is achieved by formal verification, also known as Logical Equivalence Checking (LEC).

Timing(Frequency) is one of the key performance metrics of a Chip along with Power and Area. 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 a specialized skill for VLSI engineers working on RTL Design, Synthesis and Physical Design. Knowledge of Timing is also essential for most of the Engineers working on ASIC flow.

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

Uniqueness of this Course:

This course offers integrated learning for Synthesis, Equivalence Checking & Sign-off STA under one umbrella using Industry Standard EDA tools. It not only covers the tool aspects but also provides in-depth technical knowledge.

What do you get out of this Course?

  • In depth know-how of using design compiler for synthesizing the design modeled in Verilog or VHDL
  • Logical Equivalence check between Golden & Implemented design.
  • Timing Analysis and Timing Closure of Pre-Layout(Synthesized) and Post-Layout designs.

What Opportunities could open up for you?

  • RTL Design/Application/CAD engineers can migrate to Synthesis/STA engineer roles or up-skill themselves to deliver effectively in their current roles.
  • FPGA engineers can migrate to Synthesis/STA engineer roles.
  • By acquiring Timing Closure proficiency, PD engineers can significantly improve turn around times of their blocks/designs. This in turn will help save valuable working hours as well as open up new growth opportunities.

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.
