ITS ALL ABOUT VLSI CAREER
ASIC Design & Verification Course Overview:

The term ASIC stands for Application Specific Integrated Circuit. It is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use.

In ASIC Design and Verification process, Verification consumes 50% to 70% of the effort of design cycle and is on the critical path in the design flow of multimillion gate ASICs. Hence verification has become the main bottleneck in the design process.

The functional verification bottleneck is an effect of raising the design abstraction level. Majority of ASICs require at least one re-spin, and with 71% of re-spins are due to functional bugs.

An ASIC Verification methodology provides the building blocks needed to quickly develop well-constructed and reusable verification components and test environments. FPGA Emulation is another means of verifying complex ASICs, and it helps to capture real time bugs.

Vlsicareeris now offering career courses geared towards meeting this rising global demand.
