Compilation of 4KB SRAM breaks with KeyError: 'nand4_leakage'

Open nklimov-dev opened this issue 2 years ago • 2 comments

Describe the bug A clear and concise description of what the bug is.

The compilation of a 4x1024 SRAM breaks with an error:

KeyError: 'nand4_leakage'

yielded from:

File "/openram/compiler/modules/pnand4.py", line 328, in analytical_power power_leak = spice["nand4_leakage"]

(Please refer to log output below).

To Reproduce What did you do to demonstrate the bug? Please include your configuration file used.

After cloning the OpenRAM repository, I entered the repository folder and ran "sudo make library", then "sudo make pdk", and then "sudo make install". Then, I went to the docker/ directory and ran "sudo make build". Then, I ran "sudo make mount". Inside the Docker container, I cloned the OpenRAM repository (to obtain the compiler), and ran the command "python3 $OPENRAM_ROOT/sram_compiler.py sram_4_1024_sky130.py". The contents of the configuration file "sram_4_1024_sky130.py" is provided below:

word_size = 4 num_words = 1024

tech_name = "sky130"

nominal_corner_only = True process_corners = ["TT"] supply_voltages = [3.3] temperatures = [ 0, 25, 100]

num_rw_ports = 2 num_r_ports = 0 num_w_ports = 0

output_path = "temp" output_name = "sram_{0}{1}{2}".format(word_size,num_words,tech_name)

Expected behavior A clear and concise description of what you expected to happen.

I was expecting for the compilation to finish and yield all of the output files. I did obtain the following files: functional_stim.sp sram_4_1024_sky130.lvs sram_4_1024_sky130.sp sram_4_1024_sky130.lib sram_4_1024_sky130.log sram_4_1024_sky130.lef sram_4_1024_sky130.gds

However, I did not obtain the following output files: sram_4_1024_sky130.v sram_4_1024_sky130.py sram_4_1024_sky130.html

I am not sure if compilation has been completed successfully, although the physical area of the design is reasonable as depicted by KLayout using the GDSII file that was generated from this run.

Logs If applicable, add logs or output to help explain your problem.

The log file has the same contents as the console output.

You probably should look into those wall of error messages first, but to fix the KeyError just add spice["nand4_leakage"] = 1 to technology/sky130/tech/tech.py.

Yes, the above is a fix for the leakage. All the numbers are placeholders right now.

I thought the other warning/error was fixed but evidently not. It shouldn't be an issue.

I'll leave this open so we fix them in the next release
