The purpose of this lab is to familiarise you with the efabless OpenLane VLSI design flow and the Skywater 130nm PDK. OpenLane is an open-source VLSI flow built around open-source tools. That is, it's a collection of scripts that run these tools, in the right order, transforming their inputs and outputs as appropriate, and organising the results (like Berkeley's own HAMMER . OpenLANE is an automated RTL to GDSII flow based on several components including OpenROAD, Yosys, Magic, Netgen, Fault and custom methodology scripts for design exploration and optimization. - efabless/openlane Short overview of the OpenROAD RTL-to-GDS tool status, and efabless's experience with OpenLane built on top of OpenROAD OpenLane is an automated RTL to GDSII flow based on several components including OpenRoad, Yosys, Magic, Netgen, Fault and custom methodology scripts for design exploration and optimization
OpenLANE supports two main use cases. First, It can be used to harden designs from their RTL HDL models obtaining what we will refer to as soft macros. The second use case is integrating macros into a complete chip. To demonstrate its capabilities, OpenLANE has been used to successfully tape out a family of RISC-V based SoCs called striVe Install SkywaterPDK and OpenPDK using OpenLane. Clone and Install OpenLane. This will also grab and install SkywaterPDK and OpenPDK for you: ```shell export PDK_ROOT=(where pdks will be installed) cd \$PDK_ROOT. git clone https://github.com/efabless/openlane.git -b mpw-one-a. cd openlane export OPENLANE_ROOT=\$(pwd) make ``` 2 . OpenLane main objective is to generate a clean layout from RTL designs with no-human in the loop

Following the order in efabless/openlane: OpenLANE Design Stages is suggested. Add the missing tools to collection centos-7. This collection is currently empty (it contains the base dockerfile only). It was added because OpenLane containers are based on centos-7, but may be updated to centos-8 The Google/SkyWater shuttle runs on efabless: Submits project to efabless Gets back packaged parts and parts assembled on a development board Creates open-source IP The designer: Puts IP in the Caravel design Posts project on github page 3 CHIPS Alliance is excited to announce that the hardware development community can submit their open source design projects to Efabless.com for space on their forthcoming shuttle. This opportunity comes after the success of having 40 submissions for the MPW-ONE shuttle; 60% of those designs were submitted by first-time ASIC designers. MPW-TWO is.

There is a dependency on vsdflow, though for fresh users and with Windows or fresh Unix machines The efabless Caravel chip is a ready-to-use test harness for creating designs with the Google/Skywater 130nm Open PDK. The Caravel harness comprises a small RISC-V microprocessor based on the simple 2-cycle PicoRV32 RISC-V core implementing the RV32IMC instruction set (see riscv.org page ), a 32-bit wishbone bus, and an approximately 2.8mm x 2.8mm open area for the placement of user IP blocks

Audience. Busy people who already have digital design experience and want to learn how to make a digital ASIC and apply to either the Google sponsored free shuttle or Efabless $10k shuttle. You can bring some digital designs already simulated or tested on an FPGA Overview ¶. This repo contains a sample user project that utilizes the caravel chip user space. The user project is a simple counter that showcases how to make use of caravel's user space utilities like IO pads, logic analyzer probes, and wishbone port. The repo also demonstrates the recommended structure for the open-mpw shuttle projects

It is the flow that efabless used in their sw130 tapeouts. OpenROAD has not been tuned for sw130 yet. Eventually OpenLane will be obsoleted by updates to OpenROAD, but until then it serves as a bridge to ensure that there is a tapeout-ready flow for sw130 Open_PDKs will set up an environment for using the SkyWater sky130 process with open-source EDA tools and tool flows such as magic, qflow, openlane, netgen, klayout, etc. For more information on the Google/Skywater process, please join the Slack workspace from this URL: https://join.skywater.tools or https://invite.skywater.tools
This will be continuously updated to the latest openlane tag until we reach a stable version of caravel. Then, you have two options: Create a macro for your design and harden it, then insert it into user_project_wrapper. Flatten your design with the user_project_wrapper and harden them as one 2nd mile-stone in field open-source (efabless open-lane EDA + Google/Sky130 open-process) GitHub is indeed the new RESUME for VLSI industry. Really, if you looking forward to judge a new candidate for a role in your company, ask for GitHub project link Eventually OpenLane will be obsoleted by updates to OpenROAD, but until then it serves as a bridge to ensure that there is a tapeout-ready flow for sw130. It is more or less a fork of OpenROAD. The OpenROAD developers focused on features and support for advanced finFET nodes; efabless focused on full tapeout support for sw130
