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.
