Basilisk: Achieving Competitive Performance with Open EDA Tools on an Open-Source Linux-Capable RISC-V SoC
arxiv(2024)
摘要
We introduce Basilisk, an optimized application-specific integrated circuit
(ASIC) implementation and design flow building on the end-to-end open-source
Iguana system-on-chip (SoC). We present enhancements to synthesis tools and
logic optimization scripts improving quality of results (QoR), as well as an
optimized physical design with an improved power grid and cell placement
integration enabling a higher core utilization. The tapeout-ready version of
Basilisk implemented in IHP's open 130 nm technology achieves an operation
frequency of 77 MHz (51 logic levels) under typical conditions, a 2.3x
improvement compared to the baseline open-source EDA design flow presented in
Iguana, and a higher 55
design. Through collaboration with EDA tool developers and domain experts,
Basilisk exemplifies a synergistic effort towards competitive open-source
electronic design automation (EDA) tools for research and industry
applications.
