Errors on characterization process

[andreili]

I try to characterize generated SRAM model, but see a wall of fail's on "Port 1" only ("Port 0" are ok). And this is don't going to sctipt terminate.
Version: 1.2.40
To reproduce, run this config:

word_size = 32 # Bits
num_words = 32
human_byte_size = "{:.0f}kbytes".format((word_size * num_words)/1024/8)

write_size = 8 # Bits

num_rw_ports = 2
num_r_ports = 0
num_w_ports = 0
num_spare_rows = 0
num_spare_cols = 0
esp_name = "esp_aux_dual"
delay_chain_stages = 21
verbose_level = 1
tech_name = "sky130"
nominal_corner_only = True
route_supplies = "ring"
#route_supplies = "left"
check_lvsdrc = True
uniquify = True
#perimeter_pins = False
netlist_only = True
analytical_delay = False
num_threads = 4
num_sim_threads = 8
ports_human = "{0}rw{1}r{2}w".format(num_rw_ports,
        num_r_ports,
        num_w_ports)
output_name = "{tech_name}_sram_{human_byte_size}_{ports_human}_{word_size}x{num_words}_{write_size}".format(**locals())
output_path = "macro/{output_name}".format(**locals())

Expected: Same behaviour into both ports.

And have a wall of same errors on leakage power simulations.
