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 am using docker for the tool: Xschem, but I am not getting the waveform. Could you please help. (Also how to save the circuit (.sch file), since saved file (.sch) getting deleted automatically once I come out of the docker.) @Harald Pretl

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

I'm trying install OpenRoad flow script in Ubuntu 20.04 with docker based using git clone --recursive https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts cd OpenROAD-flow-scripts ./build_openroad.sh but failed to complete.

Hi, I am trying to run LVS on an inverter that I created in xschem and the layout in magic. I've read a few other similar posts about the same issues that I'm having, but I cannot seem to get it to work. I'm capable of running LVS between the two spice files, but it always tells me that there are no pins in my cells. I've seen that I need to include the pins on the . subckt line in the spice files, but when I include that line in my spice files, then the lvs states that my spice file contains no instances, devices, or nets. Any help would be greatly appreciated.

Hello, I am quite new to Linux and xschem. I apologise first if I am asking a very simple question. I used this procedure (Link here: https://gist.github.com/chiraag/248d2042df02ac759079adf25c65c2fa) to install xschem. The steps

make

and

make install

threw errors. When I examined the results of the previous step:

export xschem_ver=$(git describe --tags)
./configure --prefix=$HOME/programs/xschem/$xschem_ver \
    --user-conf-dir=$HOME/programs/conf/xschem/dotxschem \
    --user-lib-path=$HOME/programs/conf/xschem/xschem_library

I could see that there was this error:

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 ?

I get the following error during synthesis

ABC: Error: The network is combinational.

. Any idea how to get around it? or what might be causing it? Thanks for the help!

hey, i'm running into a

[ERROR PSM-0042] Unable to connect macro/pad Instance manchester_baby to the power grid.

error, which i'm struggling to solve i have

"SYNTH_USE_PG_PINS_DEFINES": "USE_POWER_PINS"

in my

manchester-baby/config.json

and in

lincoln_gfmpw/config.json

(which is basically my version of the user_proj_example) both of the .v source files for those modules are using the ``ifdef USE_POWER_PINS` header, and i can see that they are present in the gate-level versions of the verilog source, but for some reason it just isn't connecting it. interestingly you can see a gap in the openroad gui where it didn't bother. i've attached my issue_reproducible if anyone is able to help, thank you :)
