Abstract

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

analysis.
