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

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.

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

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.

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?
