Verification (DRC/LVS/PEX)—
Calibre
• DRC( Design Rule Check )
– checks physical layout data against fabricationspecific
rules
• LVS( Layout Versus Schematic )
– checks the connectivity of a physical layout
design to its related schematic
• PEX( Parasitic EXtraction using XCalibre )
– extracts the parasitic effect resulted from the
interconnection of layout design

Calibre

Calibre DRC –(1)

Calibre DRC –(2)

Calibre DRC –(3)

Calibre DRC –(4)

Calibre DRC –(5)

Calibre DRC –(6)
• Open the drc file, you can check the design
rule

Calibre DRC –(7)
• EX:

Type of Parasites

Calibre PEX –(1)

Calibre PEX –(2)

Calibre PEX –(3)

Calibre PEX –(4)

Calibre PEX –(5)
– Paratactic Extraction (R+C+CC)
– .pex file, .pxi file and .pex.pex
• Pex file is just like the SP file you exported
from composer
• Pxi file: Parasitic capacitance between metal
line and devices
• Pex.Pex: Parasitic resistance capacitance of
metal line

Calibre PEX –(6)
• Hspice
– Remember to put all 3 files along with the .lib in
the same folder
• Example: subckt in pex file
