Hello All, I was trying to simulate our design using SPICE. I needed the model files for NMOS and PMOS of skywater 130 nm pdk. I searched the website and it says that the model files for the SPICE is ready to use but upon checking the git hub open source I could not manage to get those model files. I would really appreciate anyone of you helping me to get those model files for PMOS and NMOS. Thanks in advance!!

Hi All, I am using the open PDK sky130 tech file for magic which I have linked to my install path using ln -s, When I invoke #magic with #sky130 (magic -T sky130) I get quite a few warnings (Picture attached) Magic does have access to sky130 when I try to layout my designs but I keep seeing a repetition of these pink warnings at most of the steps which are really annoying. Any ideas on how to fix this? #ieee-sscs-dc-22

Is there a way for Magic VLSI to become more usable? I read the tutorial, but everything just does not make sense. The layers is completly unusable because you don't know which layers is which, as they are not labeled.

Hi, I am getting this LVS mismatch issue for unmatched pins. I don't know if this is a valid problem as all the pins are there, just the order doesn't match.

Hi, I'm trying to generate a LEF file from a layout made in cadence using magic, not sure if magic supports that and what are the steps to take. Thanks.

I'm trying to run Verilog-A using ngspice. I created a .va file as shown in the image below and compiled it into OSDI format using openvaf. Then, I created a .sp file as shown in the image below and tried to run it, but I encountered the following error. I would appreciate it if you could let me know what might be the issue. Thank you in advance for your help

What open source lithography (simulation, OPC, etc.) tools do people know of? I'm only aware of this one which is kind-of open source (research only, must request access to code): https://www.cerc.utexas.edu/utda/download/ELIAS/index.html

is there any tutorial on how to connect ngspice to sky130 ?

Hello, I don't understand how can i save the current into ammeter. How can i save the current? and the second question is, how can i plot Ids(VDD) for vgs_nmos=0.5, 1, 1.5? i tried also dc VDD 0 1.8 0.1 vgs_nmos 0.5 1 1.5, but i am not able to plot the chart ids(vds) for this three vgs voltage
