Hi ,

What is the typical runtime , seems the output is stuck for ~15mins :

python3 $OPENRAM_HOME/openram.py myconfig_sky130.py

The runtime depends multiple factors. I am mentioning few:

  1. Total size of memory (word size * words)
    • For a 32 x 1024, it takes me around 90+ minutes
  2. Performance of your linux machine
    • Generation of same memory size takes significantly different amount of time on two different machines

For a 32 x 1024, it takes me around 90+ minutes :: Ok so i should wait .. Tried on smaller _2.py file --> seems generating output , so flow setup looks fine... Only runtime issue
