I am working on access to the open source tools to use the sky130 pdk. But would like to experiment access in cadence Virtuoso. That is, have open access files otherwise I can not view the schematic and layout symbols etc.

@User can you send me the NDA so my company can have a look?

You're best going to the skywater fab website and getting in touch with them there if you want to engage in the NDA

Did you ever see the parasitic-Nwd between vdd and gnd for LVS and QRC? LVS passed but the post-sim was stuck because no model

Hi all, I am seeing units mismatch between spectre model file and schematic parameters when using nmos_tt.pm3 and pmos_tt.pm3 when using Cadence design tools. "/process/hosted/skywater/s130/oa/V2.0.0/s130/MODELS/V3.0.1/SPECTRE/S130//./../S130X/nmos_tt.pm3" 49: tb_passgate.I0.MN8:  The length, width, or area of the instance does not fit the given lmax-lmin, wmax-wmin, or areamax-areamin range for any model in the `tb_passgate.I0.MN8.nmos_model' group. The channel width is 4.200000e-01 and length is 1.500000e-01. Specify channel width and length that do not exceed the referenced maximal area Lmax=1.000000e-04, Lmin=1.500000e-07, Wmax=1.000000e-04,and Wmin=3.600000e-07. You can choose the nearest model by setting the value of `soft_bin' option to `allmodels' I am using "pmos" and "nmos" pcells (multi finger devices)? Do they have some known issues? Has anyone seen this issue?

does anyone have an

any resources on how to add this pdk as a virtuoso library?

Hello All,

Quick Check if anyone has created / built the SKY130 technology and standard cells and PADs OA database as i am working on it

Has anyone made progress on converting the sky130 library to be virtuoso/spectre compatible? Does anybody know the fundamental things that are missing/incompatible? I want to put some time into modifying the library but would appreciate guidance from someone who has tried before

Hello, wanted to know if there was any updates on importing the Skywater 130nm PDK library into the Cadence Virtuoso environment?

I am new to this channel

I don’t think the sk130 pdk is currently available for Virtuoso (except the skywater s8 pdk - compatible with sky130, but NDA is required).

Hello everyone! It is great to join this community. I have post a similar question in the general thread and would like to check if there are solutions in the channel: Do we currently have a guide of using the PDK in Cadence Virtuoso? Is it now compatible with Virtuoso? Any feedback is greatly appreciated!

Hello, I like to kindly ask about any updates on importing Skywater 130nm PDK into Cadence Virtuoso? Or it is still just compatible with Skywater S8 PDK and Skywater 130nm PDK requiring NDA?

Is there a way to import skywater130 to Virtuoso?

Hello everyone. I'll be looking into getting the NDA with Skywater to use the virtuoso pdk, but will also have students use the open source tool flow. Has anyone looked into developing an open source pdk for Cadence that would be freely available online? Would that be impacted by the NDA with Skywater or affect the ability to fab on the shuttle program?
