data not getting written into memory cells

[KolliparaAbhishekAnand]

Describe the bug
In memory macros of size 16_64 , 16_128 , data is not getting written into memory cells . this is observed by testing on generated .sp files using ngspice as simulator tool.

Version
v1.2.18 and commit 3620d56

To Reproduce
1.I wrote different content into memory cells , and every time the data stored is always zero in memory cells.
2. also tested the functional_stim.sp file generated by openram . the file will include some pre-known results which we should be able to get by running this test stimulus file . pre-known results and actual simulation results didn't match.`

Expected behavior
data should be written into memory cells properly. i observed this behaviour in those memory macros with word size 64 and 128.

Can you attach the config you used. I am having trouble replicating this issue.

Data word size

word_size = 64

Number of words in the memory

num_words = 16

human_byte_size = "{:.0f}kbytes".format((word_size * num_words)/1024/8)

netlist_only=True

num_spare_cols=1
num_spare_rows=1
tech_name = "sky130"
process_corners = [ "TT"]
supply_voltages = [ 1.8 ]
temperatures = [ 27 ]
num_rw_ports=1
num_r_ports=0
num_w_ports=0
write_size=None
ports_human='1rw'

Disable analytical models for full characterization (WARNING: slow!)

analytical_delay = False

file_path="/home/abhishek/SINESyslab/OpenRAM/macros/sram_configs/"
import os
exec(open(os.path.join(os.path.dirname(file_path),'sky130_sram_common.py')).read())

I am able to read and write with these stimulus files.
functional.tar.gz

Could you perhaps send your stimulus?

[KolliparaAbhishekAnand]

I am getting problem in those circuits in which number of words are 16 and data bits/word size = 64 . you have taken exactly opposite of it.

[bugraonal]

Ah, I see. I'll try that one.

[KolliparaAbhishekAnand]

are you able to replicate the issue??
