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!!

error in my basic inverter testbench. Tried several ways but could not remove this error. Can you please check. Attaching my inverter TB for debugging.

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

Hello all As, I am designing the inverter circuit in xschem and trying to generate the netlist by designing it's symbol as ,I need that spice file to generate the layout in magic.But, when I am generating the netlist ,it's showing this error "undriven node :Vout" due to which the waveform is not generating and it's showing no such vector Vout. So, can anyone please tell me that why this error is coming and how to resolve this error ?

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