hello, does anyone know how to use this command lvs ignored=1, I put it in the element but the LVS continues to validate it

You may want

spice_ignore

instead. How are you running LVS?

@Juan Andres use

lvs_ignore=true

. By convention attributes that are boolean use 'true' or 'false'. I will someday also allow 1 and 0 for this. @Aidan Medcalf

lvs_ignore

is similar to

spice_ignore

, however all the

lvs_ignore

attributes are used only if global option

Simulation->Set lvs_ignore variable

is set. This allows to switch between simulation netlists and LVS netlists easily when some differences are needed. On the other hand

spice_ignore=true

causes the component to be ignored in spice netlists (but continues to exists in the other netlists, unless verilog_ignore / vhdl_ignore are also set.

Thanks
