Hi, ALL I am just starting to understand how OpenRAM works with sky130 pdk by following the OpenRAM Github document below https://github.com/VLSIDA/OpenRAM But stacked on ERROR as you can see attached screenshot, can someone advise me to find a way to cleanup it? Thank you… I would like to share what I made below. 1. Cloned OpenRAM

$ git clone <https://github.com/VLSIDA/OpenRAM.git>

2. Build docker tool

$ cd OpenRAM/docker
$ make build

3. export below.

$ export OPENRAM_HOME="$HOME/OpenRAM/compiler"
$ export OPENRAM_TECH="$HOME/OpenRAM/technology"
$ export PYTHONPATH="$OPENRAM_HOME:$OPENRAM_TECH/sky130:$OPENRAM_TECH/sky130/custom"

4. edit myconfig.py as following

# Data word size
word_size = 8
# Number of words in the memory
num_words = 128
num_rw_port = 2  # In case "1" generate ERROR
tech_name = "sky130"
nominal_corner_only = True
output_path = "temp"
output_name = "sram_{0}_{1}_{2}".format(word_size,num_words,tech_name)

5. Compile it

$ cd OpenRAM
$ make pdk
$ make install
$ python3 $OPENRAM_HOME/openram.py myconfig

6. Stucked with attached ERROR.

Which commit of openram are you using? In #5, it is best to run this in the docker, but I don't suspect that this is the issue. The macros subdirectory has a makefile to do it.

Thanks and will try to your advice. BTW is there any document or reference about col/row configuration guideline?

There's an error message that is pretty descriptive, but other than that, no. It's dictated by the bitcell so it is process specific.

@Matthew Guthaus Thanks, Got a GDS with Sky130 by your advice that adding following into myconfig.py; num_spare_cols = 1 num_spare_rows = 1 Will try some other config!!
