i'm new in using calibre for layout verification . i'm designing an ASIC project .

after the synthesis (using sysnopsys-design compiler) and routing (using the first encounter-cadence)

i want to perform the layout verfication using the calibre - mentor graphics - software .

the problem : when opening the .gds file , i see nothing ! only black screen

the top cell name and the cells names , but nothing inside ! ( technology fles : tsmc90n)

how to solve the probleme plz ?
