@User I am trying Synopsys tools for an open-source FPGA IP generation based on the skywater PDK. Currently, I am blocked by the technology file. If you can share your experience, it will help a lot. Thanks!

Which tools are you interested in running?

I am using Synopsys IC compiler 2

I have a flow for creating db/mw/ndm, haven’t push the ndm part to GitHub yet, I manually created ITF from layer diagram to get tluplus, so parasitics may need revision, Looking forward to get some feedback, can push changes later today to my fork

It looks great! If you can share the scripts or result files, I can try instantly.

ok, I just pushed the files and tested fresh on my env, please give it a try https://github.com/20Mhz/skywater-pdk/ Please checkout the synopsys branch. You will need following software, let me know if you get stuck: • lc_shell - library compiler • mw - Milkyway • icc2_lm_shell - Library Manager • grdgenxo - StarRC

Thanks a lot!

Are you able to get started? You should be looking into vendor/synopsys

Yes. I got these files but i realize I miss the milkyway. So I am trying to install it and then continue.

Ideally it shouldn’t be required, but I’m using the lefs from mw and not the originals to create the ndms

Hi, I have tried to the run the scripts but have seen errors when creating db. I attached the log file here. My understanding is that one of the paths is hard coded and not adapted to local environment.

sorry, I thought I had fixed that, basically LIBRARY variable on Makefile needs to point to root directory, I push the change now, but didn't test, can you try? other wise just modify that variable

No worries. I will try today.

I'm open to meet today if you want to debug live, cheers

I have just tried but I see other problems. I am open to a live debug but this afternoon I am booked. The earliest I can make is 5 pm MST. Are you ok with that?

left extra space after the LIBRARY value, fixed now... if this is 12:30pm for you, then I'm 3 hours ahead, I'll be ok with a 30 min at your 5pm. Regards

Yes. It was 12:30 pm on my side. I will try the updated version soon. See you at 5 pm today. Thanks for the help

Hi Xifan, just pushed some of the fixes. The one that was stopping you is this on line 42 of lm.tcl, replace with below

check_workspace -details all -*allow_missing*

Hope you can proceed now... let me know. Cheers,

Sure. I will try it tomorrow. Thanks for the update

Happy to hear, do let me know how it goes setting up the implementation flow or if you need advice. bests.

Great! I will try it next week.

just filed the pull request, having some issues though
