Does the precheck on Efabless server use the lastest version on Github? I got a lot of DRC Violations (might be with the SRAM macro):
Copy code

I know that special stuff was needed to pass designs with SRAM, but I don't know the status of it. Maybe @Tim Edwards or @Matthew Guthaus could help

@Hieu Bui: Which SRAM macro are you using? Our precheck is supposed to be abstracting any of the macros from the efabless sky130_sram_macros library so that those blocks are hidden from magic's DRC checker, since magic's tech file doesn't encode the special SRAM DRC rules.

@Tim Edwards: I am currently using 4kbyte SRAM. I am trying to change it into 2kbyte SRAM because @Matthew Guthaus found some problems with the 4kbyte SRAM simulation. Anyway, I ran the precheck on my machine, it has 8 steps while the submitting the job on Efabless server only has 6 steps.

@Hieu Bui just confirming that the precheck repo has been update to abstract the sram macros, but the precheck on our site is still being updated. should be corrected soon.

@jeffdi What about me? I have other SRAMs that are not in the sram repo.

I don't want people to use them so I haven't put them there.

@Matthew Guthaus you can include them directly and we will work around for your project.
