12.1 Constraints - How do I LOC a PAD to an edge, multiple sites, or banks?

Description

How do I LOC a given PAD to a particular side of the die?  

For more information, see (Xilinx Answer 3753).

Solution

The syntax "L, R, T, B, TL, etc." is supported for PAD LOCs as follows: 

NET mysig LOC = T; 

To LOC a PAD to any location on a given edge or list of location, enumerate the list of IOB sites as follows: 

NET mysig LOC = A2, B3, A4, B5, A6, B7; 

To LOC a PAD to a bank of the device, use the BANK number as follows: 

NET mysig LOC = BANK2; 

Note that MAP will not accept the wild cards in the IOB site locations, so you cannot use: P?, P1?, P2?, P3?, etc., to LOC to sites P1 through P39. Instead, you must explicitly list the sites.
