Hi all, I am new using open source EDA tools. Is there any way of converting a .lib.json into a .lib? I am trying to perform synthesis with Yosys using sky130 PDK, however I noticed there is only .lib.json available in the official GitHub repository.

Hi @those who were selected in MPW2/3. Jeff had an announcement on 24th Feb. Have you guys received the board and/or part? If yes, please respond and let the community know. It is not very clear on https://efabless.com/shuttle-status

Hi all! I am not able to access and install SKY130 pdk in #C01DH7SPX41 Did anyone else face this issue and could solve it? Thanks

What kind of cost would one be looking at to actually produce chips (like order of magnitude, not asking for a formal quote) ? Imagine, an OSS design, selected for the google shuttle, chips comes back, they work awesomely and now I want to build more.

Hello, I encountered an LVS error. It seems the error is related to mismatched pin names of MOSFETs. Done anyone know how to solve it?

Hey! Seems like there is bug in xschem (or ngspice) using sky130 pdk: If doing a noise simulation (.noise) within placed a nfet_01v8 in xschem and saving data in ngspice using write noiseSim.raw (for example), ngspice crashes and writes an error: "vector @m.xm1.msky130_fd_pr___nfet_01v8[ib] is not available or has zero length. free(): invalid pointer ...". It seems that only nfet01v[id] has data and ngspice can't handle that. A temporary solution would be (for example) instead of write noiseSim.raw: setplot noise1 write noiseSim.raw @m.xm1.msky130_fd_pr__nfet_01v8[id] @r1[i] inoise_spectrum onoise_spectrum set appendwrite setplot noise2 write noiseSim.raw @m.xm1.msky130_fd_pr__nfet_01v8[id] @r1[i] inoise_total onoise_total

Is there a way to convert a Verilog netlist to SPICE netlist to perform a mixed-signal simulation on a gate level with analog circuitry?

Hi All. Running a TT sim in xschem/sw130 using TT models (taken from code.sym in the top.sch landing page for this pdk, as shown below). I can run ss/sf/fs/ff models separately. How do I run them in the the same sim so that I can sweep across process? Does anyone have an example where they do something like this which would kick off 5 model corners simultaneously, ideally outputting all the results in a format that could be read into a spreadsheet which allows me to tabulate performance across corners.

Does anyone know of a good open-source 2D field solver? If it can handle dielectric interfaces that would be ideal

Hi everyone, In skywater 130nm pdk, are mismatch coefficients of process parameters such as A_{vth}, A_{\delta_R/R}, A_{\delta_C/C} available? If so, where can we find those mismatch coefficient values?
