VSD - SoC Design of the PicoRV32 RISCV micro-processor

Overview

In this course we take the chip forward and implement using end-to-end opensource EDA tools, and all on efabless cloud. What does this mean to us? It means, you can start innovating on a design, build RTL and do synth/PD/LVS/DRC all using opensource EDA framework and not pay a single penny for license.

The big question How is this possible?

• Run a full physical design flow from RTL design to GDSII, making it ready for tape-out.

• For freshers, this course will make them industry ready and might increase their chances of getting placed or work for tier-1 company. Assignment submission is a must.

Audience Profile

• Anyone curious to know end-to-end aspects of chip designing i.e from SOC design to tapeout, which involves lot of steps like placement, routing, clock tree synthesis, DRC cleanup, LVS fixing
• Anyone curious to know how to achieve all of above using all EDA open-source tools. Not a single penny to be paid as license fee
• Anyone who wishes to innovate, implement and submit a paper on any design, implemented using open-source tools

Prerequisites

• Knowledge about previous course "VSD - Making the Raven chip: How to design a RISC-V SoC" is nice to have, but not must to have as this course focuses on Physical design concepts, like synthesis, placement, routing, DRC, LVS and tapeout needs
• Knowledge about clock tree synthesis/STA/custom layout is nice to have and can be taken from existing VSD courses Udemy. Take up the courses "VSD - clock tree synthesis", "VSD - Static timing analysis" and "VSD - Custom Layout" on Udemy

Tools Used

Qflow –  Tool chain (like Yosys, Graywolf) for complete RTL2GDS flow
