I was wondering if it would be possible to run a program on the management SoC directly from RAM - either the DFFs or the SRAM. I came across this post from 3 years ago. It mentions that the program base address is hardcoded in the RTL. Is this still the case? I couldn't find a reference to such a base address in the RTL now.

Hi all, I am about to install the gf180 pdk and am wondering what sigma process is it? 3 I presume. Also, are they 1k/sq poly resistors available in the open source pdk? I hear there are 3 variants - A, B and C. Are all those available? If so, what do people generally reccomend and does the choice of A, B or C impact how I download / install the pdk? Thanks

I want to run DRC on GDS in klayout for sky130 pdk. Any help on how this can be done? There are several ways mentioned on slack but its still not clear.

See https://github.com/The-OpenROAD-Project/OpenROAD/blob/eb754551762a7962c94c6fc8d2ae7b0bee3a0f58/src/odb/include/odb/db.h#L3607

When will the Efabless MPW Precheck be updated? I started it overnight, but it's currently stuck at the OEB step because I'm using the foundry provided SRAM for GF180 and the version of Magic used for the precheck is smaller than v8.3.442. Locally the test passed, there I updated Magic manually for the Docker image.

We're having problems reading gf180 def files with klayout

@Mitch Bailey I am facing FEOL , BEOL errors in local precheck and trying to rectify them. Is there any way in local precheck to run only these specific checks and skip other checks in order to save time.

Hello, I'm encountering issues with the OpenLane flow. Upon executing the command "flow.tcl -design ../top -tag test1", I encounter a problem that I've been unable to resolve. This is puzzling, as a previous module ran successfully. However, after incorporating this module into the top design without significant modifications, the aforementioned error arises.

What is the difference between nfet_01v8_lvt and nfet_01v8_lvt_nf?

Hello Everyone, Magic reading GDS files: Magic throws some errors when reading our large Caravan GDS file. The errors are below:

Error while reading cell "LNA" (byte position 667929024): Warning:  Cell LNA boundary was redefined.

CIF file read warning: Input off lambda grid by 1/5; snapped to grid.

If I flatten the GDS, then Magic reads it no problem. With no errors. I would like to maintain higherarchy for LVS extraction so would anyone have any recommendations on what is causing the errors and how to resolve them? Thanks a lot!
