to build the shell script for ‘vsdflow’ on CentOS, and finally I have the first cut ready. You just need to follow steps given in below link for CentOS, and all opensource EDA tools (PNR, STA, Layout, LVS) will be installed on your system. There are 2 testcases (picorv32 and spi_slave) inside the below link to test whether all tools have been installed or not. After running the shell script in below link, you need run the testcase
So, I took up two STA tools, OpenSTA from openroad project and “——-” from “——-“, to explain, to some extent, what “bench-marking” means to me. I would also encourage everyone reading this blog to come up with their definitions of “bench-marks” for other tools and we can model that. You can fill-up “——” with one of your favorite industry grade EDA tools. The concept of benchmark won’t change
Your feedback has been continuously pushing us to the edge. And I really want to Thank You for all the support you have been giving over the past. Its due to this push, we are now releasing (especially for VLSI freshers), a package, which you just need to download/run. That would install all opensource EDA tools on your UNIX machine plus run a complete RTL-2-GDS on RISC-V core ‘picorv32’.
All you need to do is go to below github link, and follow simple 5 steps given in the README of below link:
“Design at $0” is an initiative driven by our team at VSD.Working in open environment is much easier process as all the resources are openly available, but here arise the loophole.
Steve Hoover is the founder of Redwood EDA. Steve holds a BS in electrical engineering from Rensselaer Polytechnic Institute and an MS in computer science from the University of Illinois. He has designed numerous components for high-performance server CPUs and network architectures for DEC, Compaq, and Intel. Students will learn Transaction-Level Verilog modelingtechniques to generate Verilog models in half the time using the makerchip.comfree online IDE. A new open-source RISC-V CPU development effort will be introduced that showcases flexible IP design practices.

A good takeaway from above is which is the best flow – Well, there is no single answer to this. You can use “flow 1”, if your organization is constrained by cost and comparable performance, and you can go for “flow 2” if performance is the criteria.
Question – Who doesn’t want a 3.5X improvement in their code size? I guess everyone wants efficient and effective improvement. Now these are just few tips to have the easy implementation of pipe-line. You are free to implement your ideas in TL-verilog, compile, simulate and see the improvements on your own. For few more tips, you might want to check out below course on “VSD – Pipelining RISC-
V with TL-verilog”
A working chip is all using opensource EDA tools (no more license fee). Of course, its taped-out in 180nm technology. But who knows, this might be just the beginning. Upcoming blogs will talk more about the commercial angle of this. Let’s see how it is going to benefit student/professionals/innovators community
If you learn this tool and use it to build your own applications, you might end up presenting a paper in our online conference happening soon called “VSDOpen” – The first ever online conference on opensource EDA.
