Could not find the "fet_libraries" or "fet_models" during the compilation.
Describe the bug A clear and concise description of what the bug is.
While running the compiler for an individual PDK, the compiler could not get the fet libraries or models that has defined on the each individual PDK's technology directory.
KeyError: AssertionError ERROR: file stimuli.py: line 56: Must define either fet_libraries or fet_models.
yielded from : While srart to run .sp files /home/azmir/OpenRAM/compiler/characterizer/stimuli.py Predicted to give error while start to generate other output files. Please refer to the log output given below, for better understanding.
Version: 1.2.1
To Reproduce What did you do to demonstrate the bug? Please include your configuration file used.
I checked the tech.py file on the PDK's tech directory to check whether fet_libraries or fet_models is defined or not. It is defined perfectly. Thus, I couldn't understand from where the error occurs.
Myconfig File:
#Data word size word_size = 2 #Number of words in the memory num_words = 16 num_banks=1
#Technology to use in $OPENRAM_TECH tech_name ="sky130" #You can use the technology nominal corner only #nominal_corner_only = True #Or you can specify particular corners #Process corners to characterize process_corners = ["SS", "TT", "FF"] #Voltage corners to characterize supply_voltages = [ 3.0, 3.3, 3.5 ] #Temperature corners to characterize temperatures = [ 0, 25, 100]
#Output directory for the results output_path = "sky_130_check" #Output file base name output_name = "sram_{0}{1}{2}".format(word_size,num_words,tech_name)
#Disable analytical models for full characterization (WARNING: slow!) #analytical_delay = False
Expected behavior I am expecting to generate the below files after competing the compilation
Output files: sram_2_16_sky130.lvs sram_2_16_sky130.sp sram_2_16_sky130.v sram_2_16_sky130.lib sram_2_16_sky130.py sram_2_16_sky130.html sram_2_16_sky130.log sram_2_16_sky130.lef sram_2_16_sky130.gds
The compiler can only generate the log file. | As soon as the .sp file start generating the error occurs.

I had to add this to your config to get a valid width/height of the array: num_spare_rows = 1 num_spare_cols = 1
It seems that we don't map the corners in the technology file except for TT. You can work around this with: nominal_corner_only = True for now and I will work on getting these added as a fix.
