hi
i have started with the layout for my design.
i am using umc 180 nm technology in cadence virtuoso.i generated the layout from my schematic in layout xl so the devices where there.but when i try to genrate a contact from
create>contact >m1-poly (N.B. i have actually tried for a few combinations this is just an example....this happens what ever two layers i am trying to generate a contact for)
i get the message that the umc 180 library doesnot have this contact. to be more presice it says::
*WARNING* Contact does not exist in library UMC_18_CMOS.
i dont understand .....do one has to create contacts for umc180 or is there a fault with my library.....have you idea what might be wrong??
looking forward to your advice thank you
2) my second question is when running a DRC for the same design what rule files shud i use...where do i find them
can some one explain the process of setting up the drc check....
are there any specific files if using umc180_cmos or the process is general for all processes and libraries
i have doen this for the gpdk090 library....
will the same process give me desireable results...i mean to say the same rule files??
