Why the two connecting resistors is merged?

[harryzhu]

Hi,

When I run dracula lvs check, I found the two connecting resistors merged
to one resistor, why is it? It's not my expectation, how should I resolve
it? Thanks for your help!

Give a name between the two resistors.
Have a try.

Remove R option in LVSCHK command of your LVS command file.

Pls upload ur resistor layout and write out the syntax of resistor describe.

I mayn't upload the layout since the network is unlinked to internet and limited to get it.
Normally we may divide one large res to several ones, so if we remove the R option in LVSCHK, we'll get more res and difficult to check it.
Here I have to get two res divided since their width is different and difficult to merge them.
Maybe I may try to add one label to the middle point of two res

most extracts have the option to
1) parallel & series merge
2) remove floating devices
3) remove shorted devices
4) swap terminals (drain/source usually)

in order to make the lvs easier. if you have two resistors with nothing else connected to the center tap, i see no problem if they are merged in lvs. they will be merged both in the extract and the schematic, so don't worry about an lvs error here.
