DRC and VLS for circuit using Sky130 PDK

[rtl1]

Hi,
I am using Sky130 on Cadence Virtuoso to design my circuit. I have the design and want to run DRC and LVS checks. I prefer to use Calibre, as it is available on my school PC. I have a design rule file sky130_drcRules.pvl. Whenever I try to open calibre, I get similar error:

I have never used Calibre/Assura/Magic before. Sorry if this is a stupid question. How do I run the checks?
FYI, I do not any root privileges, nor can I run sudo or install commands.

Thank you,
Ananya

If ASSURA_HOME variable has been defined, you should see Assura Menu under File/Tool Menu.

Typically someone would have integrated Calibre with Virtuoso so that in Virtuoso you'd use a menu, probably Calibre > Run nmDRC or Run nmLVS. These bring up the Calibre Interactive GUI so that you can specify the rule file, layout, the checks to run, and so on.

You can also run Calibre Interactive outside of Virtuoso, but you'll need to export your layout and schematic to a file and then specify those. To bring up Calibre Interactive, assuming $MGC_HOME and licenses are set, type "calibre -gui". You'll get a bar with some buttons; click DRC (or LVS) and fill out fields. You can also get to the manuals from the DRC or LVS GUI, under Help.

assuming your setup is done correctly and your PATH points to all the right binaries, this is how I do it:
start calibredrv, load your GDS file exported from virtuoso or innovus. from the menu, start calibreDRC. this way you can easily visualize any violations directly on the layout open in the drv window. for large designs this is perfect because drv is super fast.

PS: I was able to open Calibre through GUI. The only rules file I got from the sky130 PDK is the .pvl file, and it's throwing errors. Same with Cadence PVS. Did anyone use the sky130 PDK? Do I have to create new rule files, define them in .lib file? Just FYI, I was able to get the PDK from the OSU repo (stineje/sky130_cds: This repository is an open-source version of SKY130 to help facilitate use of Cadence Design System tools for use with Skywater 130 Process Design Kit (github.com), and not the official site due to restrictions from my school network.

Hey,
Were you able to figure out how to run DRCs with the SKY130 PDK? I am also running into issues with the .pvl file (it is not able to read the file) when trying to use Pegasus for DRCs.
