Full Understanding of the Digital IC Design Flow and the Entire Transformation
Process of Taking the Design from RTL to final bitstream on FPGA and GDSII on
ASIC. The course includes hands on training on FPGA, and final project Tapeout
and fabrication on SKY130.
Digital design flow is a lengthy process that involves many steps to take the design from RTL to
a working silicon. The objective of this course is to demystify this field and provide in-depth
understanding of the different transformations in each design step, how these transformations
can affect the final performance metrics, and how to tune the process to meet design specs.
Specifically, this course focuses on fundamental elements in the design process, including HDL
modeling, event-driven simulation, synthesis, timing analysis, technology files, standard cell
views, physical design, signoff checks, and test planning. Throughout the course, attendees learn
the salient differences in these elements when using FPGA and ASIC platforms. Both Xilinx (for
FPGA) and Cadence (for ASIC) design flows are utilized as part of the training vehicle. VIVADO
from Xilinx to cover the entire FPGA flow. On the Cadence side, ASIC simulations is
demonstrated using Incisive, while Genus is used for synthesis, and Innovus for physical
implementation. Finally, Mentor Graphics’ Calibre is used for ASIC signoff checks. The course
contains a demonstration project, which is progressively developed by the trainees throughout the
course modules to exercise the two digital design flows. The goal of this course is to provide
attendees with understandings of FPGA and ASIC digital flows and to support this understanding
with hands-on experience of tools used by the industry.
