I'm doing a resistor common centroid layout and the LVS is only detecting one of the resistors, while for the other is just detecting pairs or as individuals resistors. Is it there a problem with the layout or maybe a LVS problem? edit: the pattern of the cc is: AAAB ABAA AABA BAAA

I have had issues with LVS-matching series connections of resistors as well. Option --no_simplify may help.

@Daniel Arevalos Thanks for the testcase. This will be enhanced in next versions. Could you please open a git issue for any LVS bug you found? I will add a new option related to simplification for resistors only. Just for explanation (Will be added in docs): • For series/parallel simplication (res_only) -->

--no_series_res

,

--no_parallel_res

(Disable simplification for resistors) • Series combination --> Valid if all resistors have the same

(w: width, ps: poly_space, b:bends, m:multiplier)

◦ Will result in

l=total_length

• Parallel combination --> Valid if all resistors have the same

(w: width, l:length, ps: poly_space, b:bends)

◦ Will result as

m = no_of_parallel res
