I'm a first time user of nano encounter. How to create a blank IO pad using Encounter? I've tried to look around for simple instruction but couldn't find any.
Given only the technology LEF file, do I need to create my own IO pad LEF?
Hi Prasad,
Check your tech LEF file , it should contain the IO cell information,if it doesnt have that information, contact your library team, because we have to design IO cell and layout it using virtuso(icfb) .
If that was not ready with your library team :
--Ask what are the input and output pins and approximate loactions of those pins.
--Create a BLACK BOX using nano encounter.
BlackBox : Is a dummy module with the pin information.
You can use this in your design and go ahead until your IO team gets the info.
yes you need a lef file ask your vendor to give lef file for pad cells..
you just edit you netlist and add component io pads for all in and out pins.. and then will importing lef file it automatically regonises as pad cells and it fill place it around the core.. and add filler to fill the gap..
hi check that you took this line from lef file.. because u have to write similarly in netlist also.
it simple just declare output pin names as signal name1...
then you just have that PDIZG(Something) as component connecting name1 with output pin names..
