PEX issue with multi finger transistor

Hi,

 

I have transistor with the following configuration.

 

width of single finger = 2.5u

width of all fingers = 5u

length=232n

number of fingers=2

multiplicity=2

 

I lay this as two transistors in parallel (for common centroid) as following

 

width of single finger = 2.5u

width of all fingers = 5u

length=232n

number of fingers=2

multiplicity=1

 

Calibre PEX creates two transistor with the following configuration

 

width of single finger = 5u

width of all fingers = 5u

length=232n

number of fingers=2

multiplicity=2

 

Please let me know, why PEX is unable to replicate the schematic or layout. By the way, DRC & LVS are clean.

 

Regards
