In today’s world, the acceleration in taping out ASIC and FPGA chips is
majorly limited by the productivity in its development. While there are digital design
tools that are exceptionally good, there is a huge gap in the interaction between these
tools, resulting in overheads causing delays in the development cycle.
LGraph is an open-source database that represents digital design from any
stage of the design flow in a unified format. It supports inputs in several hardware
description languages. Tightly integrated with several open-source EDA tools, LGraph
aims to provide live results for synthesis and simulation for small changes in the design.
My contribution includes the integration of OpenTimer, an open-source tool
that performs timing analysis pre and post place and route. Presently it is possible
to receive feedback on timing for a design represented as an lgraph. With further
development, our research group looks forward to obtaining live feedback for timing
